List Of Extinct Bird Species Since 1500

Around 129 species of birds have become extinct since 1500, and the rate of extinction seems to be increasing. The situation is exemplified by Hawaii, where 30% of all known recently extinct bird taxa originally lived. Other areas, such as Guam, have also been hit hard; Guam has lost over 60% of its native bird taxa in the last 30 years, many of them due to the introduced brown tree snake.

Currently there are approximately 10,000 living species of birds, with an estimated 1,200 considered to be under threat of extinction.

Island species in general, and flightless island species in particular, are most at risk. The disproportionate number of rails in the list reflects the tendency of that family to lose the ability to fly when geographically isolated. Even more rails became extinct before they could be described by scientists; these taxa are listed in List of Late Quaternary prehistoric bird species.

The extinction dates given below are usually approximations of the actual date of extinction. In some cases, more exact dates are given as it is sometimes possible to pinpoint the date of extinction to a specific year or even day (the San Benedicto rock wren is possibly the most extreme example—its extinction could be timed with an accuracy of maybe half an hour). Extinction dates in the literature are usually the dates of the last verified record (credible observation or specimen taken); for many Pacific birds that became extinct shortly after European contact, however, this leaves an uncertainty period of over a century, because the islands on which they lived were only rarely visited by scientists.

Extinct bird species

Aepyornithiformes

* Elephant bird, ''Aepyornis maximus'' and/or ''A. medius'' (Madagascar, 16th century?)

Dinornithiformes

* Upland moa, ''Megalapteryx didinus'' (South Island, New Zealand, late 15th century?)

Apterygiformes

* West Coast spotted kiwi, ''Apteryx occidentalis'' (South Island, New Zealand, c. 1900)
*:A doubtful form known from a single bird; may be a little spotted kiwi subspecies or a hybrid between that species and the rowi.

Anseriformes

Ducks, geese and swans
* Crested shelduck, ''Tadorna cristata'' (Northeastern Asia, late 20th century?)
*:A relict species from northeastern Asia. Officially critically endangered due to unconfirmed reports made between 1985 and 1991.
* Réunion sheldgoose, ''Alopochen kervazoi'' (Réunion, Mascarenes, c.1690s)
* Mauritius sheldgoose, ''Alopochen mauritianus'' (Mauritius, Mascarenes, c.1695)
* Amsterdam wigeon, ''Mareca marecula'' (Amsterdam Island, South Indian Ocean, c.1800)
* Saint Paul Island duck, ''Anas'' sp. (Saint Paul Island, South Indian Ocean, c.1800)
*: Only known by a painting from 1793. Might be identical with the Amsterdam wigeon or a distinct species or subspecies.
* Mascarene teal, ''Anas theodori'' (Mauritius and Réunion, Mascarenes, late 1690s)
* Mariana mallard, ''Anas oustaleti'' (Marianas, West Pacific, 1981)
* Finsch's duck, ''Chenonetta finschi'' (New Zealand, possibly survived to 1870)
* Réunion pochard, ''Aythya'' cf. ''innotata'' (Réunion, Mascarenes, c.1690s)
*:A bone of a pochard found on Réunion seems to resolve the reports of ''canards'' other than the Mauritian duck having occurred on the island. The taxonomic status of this form cannot be resolved until more material is found, however.
* Labrador duck, ''Camptorhynchus labradorius'' (Northeastern North America, ca. 1878)
* New Zealand merganser, ''Mergus australis'' (New Zealand, Auckland Islands, Southwest Pacific, c.1902)

Galliformes

Quails and relatives

See also Bokaak "bustard" under Gruiformes below
* The pile-builder megapode, ''Megapodius molistructor'' may have survived on New Caledonia to the late 18th century as evidenced by descriptions of the bird named ''"Tetrao australis"'' and later ''"Megapodius andersoni"''.
* The Viti Levu scrubfowl, ''Megapodius amissus'' of Viti Levu and possibly Kadavu, Fiji, may have survived to the early 19th or even the 20th century as suggested by circumstantial evidence.
* Raoul Island scrubfowl, ''Megapodius'' sp. (Raoul, Kermadec Islands, 1876)
*:A megapode is said to have inhabited Raoul Island until the population was wiped out in a volcanic eruption. It is not clear whether the birds represent a distinct taxon or derive from a prehistoric introduction by Polynesian seafarers.
* New Zealand quail, ''Coturnix novaezelandiae'' (New Zealand, 1875)
* Himalayan quail, ''Ophrysia superciliosa'' (North India, late 19th century?)
*:Officially critically endangered. Not recorded with certainty since 1876, but thorough surveys are still required, and there was a recent set of possible (though unlikely) sightings around Naini Tal in 2003. A little-known native name from Western Nepal probably refers to this bird, but for various reasons, no survey for ''Ophrysia'' has ever been conducted in that country, nor is it generally assumed to occur there (due to the native name being overlooked).

Charadriiformes

Shorebirds, gulls and auks
* Javan lapwing, ''Vanellus macropterus'' (Java, Indonesia, mid-20th century)
*:Officially classified as critically endangered, but as this conspicuous bird has not been recorded since 1940, it is almost certainly extinct.
* Christmas sandpiper, ''Prosobonia cancellata'' (Kiritimati Island, Kiribati, 1850s)
* Tahiti sandpiper, ''Prosobonia leucoptera'' (Tahiti, Society Islands, 19th century)
* Moorea sandpiper, ''Prosobonia ellisi'' (Moorea, Society Islands, 19th century)
*:Doubtfully distinct from ''P. leucoptera''.
* North Island snipe, ''Coenocorypha barrierensis'' (North Island, New Zealand, 1870s)
* South Island snipe, ''Coenocorypha iredalei'' (South and Stewart Islands, New Zealand, 1964)
* Eskimo curlew, ''Numenius borealis'' (Northern North America, late 20th century?)
*:May still exist; officially classified as critically endangered, possibly extinct.
* Slender-billed curlew, ''Numenius tenuirostris'' (Western Siberia, early first decade of the 21st century?)
*:May still exist; officially classified as critically endangered. A few birds were recorded in 2004, following several decades of increasing rarity. There was an unconfirmed sighting in Albania in 2007. A survey to find out whether this bird still exists is currently being undertaken by the RSPB (BirdLife in the UK).
* Great auk, ''Pinguinus impennis'' (Newfoundland, 1852)
* Canary Islands oystercatcher, ''Haematopus meadewaldoi'' (Eastern Canary Islands, E Atlantic, c. 1940?)
*:Later sightings of black oystercatchers off Senegal were not likely to be of this sedentary species, but two records from Tenerife - the last in 1981 - may be.

Gruiformes

Rails and allies - probably paraphyletic

* Antillean cave rail, ''Nesotrochis debooyi'', known by pre-Columbian bones from Puerto Rico and the Virgin Islands. Stories of an easy-to-catch bird named carrao heard by Alexander Wetmore in 1912 on Puerto Rico might refer to this species.
* Hawkins' rail, ''Diaphorapteryx hawkinsi'' (Chatham Islands, SW Pacific, 19th century)
* Red rail, ''Aphanapteryx bonasia'' (Mauritius, Mascarenes, c. 1700)
* Rodrigues rail, ''Erythromachus leguati'' (Rodrigues, Mascarenes, mid-18th century)
* Bar-winged rail, ''Nesoclopeus poecilopterus'' (Fiji, Polynesia, c. 1990)
* Dieffenbach's rail, ''Gallirallus dieffenbachii'' (Chatham Islands, SW Pacific, mid-19th century)
* Tahiti rail, ''Hypotaenidia pacificus'' (Tahiti, Society Islands, late 18th – 19th century)
* Wake Island rail, ''Hypotaenidia wakensis'' (Wake Island, Micronesia, 1945)
* Tongatapu rail, ''Gallirallus hypoleucus'' (Tongatapu, Tonga, late 18th - 19th century)
* New Caledonian rail, ''Gallirallus lafresnanayanus'' (New Caledonia, Melanesia, c. 1900?)
*:Officially classified as critically endangered, the last records were in 1984 and it seems that all available habitat is overrun by feral pigs and dogs, which prey on this bird.
* Vava'u rail, ''Gallirallus'' cf. ''vekamatolu'' (Vava'u, Tonga, early 19th century?)
*:This bird is known only from a drawing by the 1793 Malaspina expedition, apparently depicting a species of ''Gallirallus''. The 'Eua rail, ''Gallirallus vekamatolu'', is known from prehistoric bones found on 'Eua, but this species is almost certainly not ''G. vekamatolu'', as that bird was flightless and hence is unlikely to have settled three distant islands. However, it probably was a close relative.
* Norfolk Island rail, ''Gallirallus'' sp., may be the bird shown on a bad watercolor illustration made around 1800.
* Chatham rail, ''Cabalus modestus'' (Chatham Islands, SW Pacific, c. 1900)
* Réunion rail or Dubois' wood-rail, ''Dryolimnas augusti'' (Réunion, Mascarenes, late 17th century)
* Ascension crake, ''Mundia elpenor'' (Ascension, Island, Atlantic, late 17th century)– formerly ''Atlantisia''
* Saint Helena crake, ''Porzana astrictocarpus'' (Saint Helena, Atlantic, early 16th century)
* Laysan rail, ''Porzana palmeri'' (Laysan Island, Hawaiian Islands, 1944)
* Hawaiian rail, ''Porzana sandwichensis'' (Big Island, Hawaiian Islands, c. 1890)
* Kosrae crake, ''Porzana monasa'' (Kosrae, Carolines, c. mid-late 19th century)
* Tahiti crake, ''Porzana nigra'' (Tahiti, Society Islands, c. 1800)
*:Known only from paintings and descriptions; taxonomic status uncertain, as the material is often believed to refer to the extant spotless crake.
* Saint Helena swamphen, ''Aphanocrex podarces'' (Saint Helena, Atlantic, 16th century)– formerly ''Atlantisia''
*Lord Howe swamphen, ''Porphyrio albus'' (Lord Howe Island, SW Pacific, early 19th century)
* Réunion swamphen or ''Oiseau bleu'', ''Porphyrio coerulescens'' (Réunion, Mascarenes, 18th century)
*:Known only from descriptions. Former existence of a ''Porphyrio'' on Réunion is fairly certain, but not proven to date.
* Marquesas swamphen, ''Porphyrio paepae'' (Hiva Oa and Tahuata, Marquesas)
*:May have survived to c. 1900. In the lower right corner of Paul Gauguin's 1902 painting ''Le Sorcier d'Hiva Oa ou le Marquisien à la cape rouge'' there is a bird which resembles native descriptions of ''P. paepae''.
* North Island takahē, ''Porphyrio mantelli'', known from subfossil bones found in New Zealand's North Island; may have survived to 1894 or later.
* New Caledonian gallinule, ''Porphyrio kukwiedei'' from New Caledonia, Melanesia, may have survived into historic times. The native name ''n'dino'' is thought to refer to this bird.
* Samoan woodhen, ''Gallinula pacifica'' (Savai'i, Samoa, 1907?)
*:Probably better placed in the genus ''Pareudiastes;'' unconfirmed reports from the late 20th century suggest it still survives in small numbers and therefore it is officially classified as critically endangered.
* Makira woodhen, ''Gallinula silvestris'' (Makira, Solomon Islands, mid-20th century?)
*:Only known from a single specimen, this rail is probably better placed in its own genus, ''Edithornis''. There are some unconfirmed recent records that suggest it still survives, and thus it is officially classified as critically endangered.
* Tristan moorhen, ''Gallinula nesiotis'' (Tristan da Cunha, Atlantic, late 19th century)
* Mascarene coot, ''Fulica newtonii'' (Mauritius and Réunion, Mascarenes, c. 1700)
* Fernando de Noronha rail, Rallidae gen. et sp. indet. (Fernando de Noronha, W. Atlantic, 16th century?)
*:A distinct species of rail inhabited Fernando de Noronha island, but it has not been formally described yet. Probably was extant at first Western contact.
* Tahitian "goose", Rallidae gen. et sp. indet. (Tahiti, late 18th century?)
*:Early travelers to Tahiti reported a "goose" that was found in the mountains. Altogether, a species of rail in the genus ''Porphyrio'' seems to be the most likely choice.
* Bokaak "bustard", Rallidae? gen. et sp. indet. 'Bokaak'
*:An unidentified terrestrial bird is mentioned in an early report from Bokaak in the Marshall Islands. It is described as a "bustard" and may have been a rail or a megapode. In the former case it may have been a vagrant of an extant species; in any case, no bird that could be described as "bustard-like" is found on Bokaak today.Spennemann (2006)
* Rallidae gen. et sp. indet. 'Amsterdam Island'
*:Unknown rail from Amsterdam Island; one specimen found, but not recovered. Extinct by 1800, or it may have been a vagrant of an extant species.

Podicipediformes

Grebes
* Colombian grebe, ''Podiceps andinus'' (Bogotá area, Colombia, 1977)
* Alaotra grebe, ''Tachybaptus rufolavatus'' (Lake Alaotra, Madagascar, 1985)
*:Officially declared extinct in 2010, 25 years after the last official sighting. Declined through habitat destruction and hybridization with the little grebe. Disappeared from only known location in the 1980s.
* Atitlán grebe, ''Podilymbus gigas'' (Lake Atitlán, Guatemala, 1989)

Cathartiformes

* "Painted vulture", ''Sarcoramphus sacra'' (Florida, United States, late 18th century?)
** A bird supposedly similar to the king vulture identified by William Bartram on his travels in the 1770s. Skeptics have stated that it is likely based on a misidentification of the northern caracara, although evidence has increasingly shifted towards it being a valid taxon that existed, either as a species in its own right or a subspecies of the king vulture, based on an independent illustration of a near-identical bird made several decades earlier by Eleazar Albin. See King vulture article for discussion.

Pelecaniformes

Pelicans and related birds

* Bermuda night heron, ''Nyctanassa carcinocatactes'' (Bermuda, West Atlantic, 17th century)
*:Sometimes assigned to the genus ''Nycticorax''.
* Réunion night heron, ''Nycticorax duboisi'' (Réunion, Mascarenes, late 17th century)
*Mauritius night heron, ''Nycticorax mauritianus'' (Mauritius, Mascarenes, c. 1700)
* Rodrigues night heron, ''Nycticorax megacephalus'' (Rodrigues, Mascarenes, mid-18th century)
*Ascension night heron, ''Nycticorax olsoni'' (Ascension Island, Atlantic, late 16th century?)
*:Known only from subfossil bones, but the description of a flightless Ascension bird by André Thévet cannot be identified with anything other than this species.
*New Zealand little bittern, ''Ixobrychus novaezelandiae'' (New Zealand, late 19th century)
*:Long considered to be vagrant individuals of the Australian little bittern, bones recovered from Holocene deposits indicate that this was indeed a distinct taxon, but it might not be a separate species.
*Réunion ibis, ''Threskiornis solitarius'' (Réunion, Mascarenes, early 18th century)
*:This species was the basis of the "Réunion solitaire", a supposed relative of the dodo and the Rodrigues solitaire. Given the fact that ibis (but no dodo-like) bones were found on Réunion and that old descriptions match a flightless sacred ibis quite well, the "Réunion solitaire" hypothesis has been refuted.

Suliformes

Boobies and related birds

* Spectacled cormorant, ''Phalacrocorax perspicillatus'' (Komandorski Islands, North Pacific, c. 1850)
*Mascarene booby, ''Papasula'' sp. (Mauritius and Rodrigues, Mascarenes, mid-19th century)
**An undescribed booby species that was formerly considered a population of Abbott's booby. Known physically only from subfossil bones, but is likely the bird referred to as a "boeuf" by early settlers. The "boeuf" was last recorded on Rodrigues in 1832 and likely went extinct following the deforestation of the island.

Procellariiformes

Petrels, shearwaters, albatrosses and storm petrels.
* Olson's petrel, ''Bulweria bifax'' (Saint Helena, Atlantic, early 16th century)
* Bermuda shearwater, ''Puffinus parvus'' (Bermuda, West Atlantic, 16th century)
* Saint Helena petrel, ''Pseudobulweria rupinarum'' (Saint Helena, Atlantic, early 16th century)
* Jamaican petrel, ''Pterodroma caribbaea'' (Jamaica, Caribbean, late 19th century?)
*:Possibly a subspecies of the black-capped petrel; unconfirmed reports suggest it might survive. Officially classified as critically endangered, possibly extinct.
* ''Pterodroma'' cf. ''leucoptera'' (Mangareva, Gambier Islands, 20th century?)
*:A wing of a carcass similar to Gould's petrel was recovered on Mangareva in 1922, where it possibly bred. No such birds are known to exist there today.
* Guadalupe storm petrel, ''Oceanodroma macrodactyla'' (Guadalupe, East Pacific, 1910s)
*:Officially critically endangered, possibly extinct, but a thorough survey in 2000 concluded the species was certainly extinct.
* Imber's petrel, ''Pterodroma imberi''
*:Described from subfossil remains from the Chatham Islands, became apparently extinct in the early 19th century.

Sphenisciformes

Penguins
* The Chatham penguin, ''Eudyptes'' sp. (Chatham Islands, SW Pacific), is only known from subfossil bones, but a bird kept captive at some time between 1867 and 1872 might refer to this taxon.

Columbiformes

Pigeons, doves and dodos

For the "Réunion solitaire", see Réunion ibis.
* Saint Helena dove, ''Dysmoropelia dekarchiskos'', possibly survived into the Modern Era.
* Passenger pigeon, ''Ectopistes migratorius'' (Eastern North America, 1914)
*:The passenger pigeon was once among the most common birds in the world, a single flock numbering up to 2.2 billion birds. It was hunted close to extinction for food and sport in the late 19th century. The last individual, Martha, died in the Cincinnati Zoo in 1914.
* Bonin wood pigeon, '' Columba versicolor'' (Nakodo-jima and Chichi-jima, Ogasawara Islands, c. 1890)
* Ryukyu wood pigeon, ''Columba jouyi'' (Okinawa and Daito Islands, Northwest Pacific, late 1930s)
* Réunion pink pigeon, ''Nesoenas duboisi'' (Réunion, Mascarenes, c. 1700)
*:Formerly in ''Streptopelia''. There seems to have been at least another species of pigeon on Réunion (probably an ''Alectroenas''), but bones have not yet been found. It disappeared at the same time.
* Rodrigues pigeon, ''Nesoenas rodericana'' (Rodrigues, Mascarenes, before 1690?)
*:Formerly in ''Streptopelia''. A possible subspecies of the Madagascar turtle dove (''N. picturata''), this seems not to be the bird observed by Leguat. Introduced rats might have killed it off in the late 17th century.
* Spotted green pigeon, ''"Caloenas" maculata'' (South Pacific or Indian Ocean islands, 1820s)
*:Also known as the Liverpool pigeon, the only known specimen has been in Liverpool's World Museum since 1851, and was probably collected on a Pacific island for Edward Stanley, 13th Earl of Derby. It has been suggested that this bird came from Tahiti based on native lore about a somewhat similar extinct bird called the ''titi'', but this has not been verified.
* Sulu bleeding-heart, ''Gallicolumba menagei'' (Tawitawi, Philippines, late 1990s?)
*:Officially listed as critically endangered. Only known from two specimens taken in 1891. There have been a number of unconfirmed reports from all over the Sulu Archipelago in 1995, however, these reports stated that the bird had suddenly undergone a massive decline, and by now, habitat destruction is almost complete. If not extinct, this species is very rare, but the ongoing civil war prevents comprehensive surveys.
* Norfolk ground dove, ''Gallicolumba norfolciensis'' (Norfolk Island, Southwest Pacific, c. 1800)
* Tanna ground dove, ''Gallicolumba ferruginea'' (Tanna, Vanuatu, late 18th-19th century)
*:Only known from descriptions of two now-lost specimens.
* Thick-billed ground dove, ''Gallicolumba salamonis'' (Makira and Ramos, Solomon Islands, mid-20th century?)
*:Last recorded in 1927, only two specimens exist. Declared extinct in 2005.
* Choiseul pigeon, ''Microgoura meeki'' (Choiseul, Solomon Islands, early 20th century)
* Red-moustached fruit dove, ''Ptilinopus mercierii'' (Nuku Hiva and Hiva Oa, Marquesas, mid-20th century)
*:Two subspecies, the little-known ''P. m. mercierii'' of Nuku Hiva (extinct mid-late 19th century) and ''P. m. tristrami'' of Hiva Oa.
* Negros fruit dove, ''Ptilinopus arcanus'' (Negros, Philippines, late 20th century?)
*:Known only from one specimen taken at the only documented sighting in 1953, the validity of this species has been questioned, but no good alternative to distinct species status has been proposed. Officially critically endangered, it might occur on Panay, but no survey has located it. One possible record in 2002 does not seem to have been repeated.
* Mauritius blue pigeon, ''Alectroenas nitidissima'' (Mauritius, Mascarenes, c. 1830s)
* Farquhar blue pigeon, ''Alectroenas'' sp. (Farquhar Group, Seychelles, 19th century)
*:Only known from early reports; possibly a subspecies of the Comoros or Seychelles blue pigeon.
* Rodrigues grey pigeon, ''"Alectroenas" rodericana'' (Rodrigues, Mascarenes, mid-18th century)
*:A mysterious bird of unknown affinities, known from a few bones and, as it seems, two historical reports.
* Dodo, ''Raphus cucullatus'' (Mauritius, Mascarenes, late 17th century)
*:Called ''Didus ineptus'' by Linnaeus. A metre-high flightless bird found on Mauritius. Its forest habitat was lost when Dutch settlers moved to the island and the dodo's nests were destroyed by the monkeys, pigs and cats that the Dutch brought with them. The last specimen was killed in 1681, only 80 years after the arrival of the new predators.
* Rodrigues solitaire, ''Pezophaps solitaria'' (Rodrigues, Mascarenes, c. 1730)

Psittaciformes

Parrots

* Sinú parakeet, ''Pyrrhura subandina'' (Colombia, mid-20th century?)
:This bird has a very restricted distribution and was last reliably recorded in 1949. It was not found during searches in 2004 and 2006 and seems to be extinct; efforts to find it again continue, but are hampered by the threat of armed conflict.
* New Caledonian lorikeet, ''Charmosyna diadema'' (New Caledonia, Melanesia, mid-20th century?)
*:Officially critically endangered, there have been no reliable reports of this bird since the early 20th century. It is, however, small and inconspicuous.
* Norfolk kaka, '' Nestor productus'' (Norfolk and Philip Islands, SW Pacific, 1851?)
* Society parakeet, ''Cyanoramphus ulietanus'' (Raiatea, Society Islands, late 18th century)
* Black-fronted parakeet, ''Cyanoramphus zealandicus'' (Tahiti, Society Islands, c. 1850)
* Paradise parrot, ''Psephotus pulcherrimus'' (Rockhampton area, Australia, late 1920s)
* Oceanic eclectus parrot, ''Eclectus infectus'', known from subfossil bones found on Tonga, Vanuatu, and possibly Fiji, may have survived until the 18th century: a bird which seems to be a male ''Eclectus'' parrot was drawn in a report on the Tongan island of Vavaʻu by the Malaspina expedition. Also a 19th-century Tongan name ''ʻāʻā'' ("parrot") for "a beautiful bird found only at ʻEua" is attested (see here under "kaka"). This seems to refer either ''E. infectus'' which in Tonga is only known from Vavaʻu and ʻEua, or the extirpated population of the collared lory which also occurred there. It is possible but unlikely that the species survived on ʻEua until the 19th century.
* Seychelles parakeet, ''Psittacula wardi'' (Seychelles, W Indian Ocean, 1883)
* Newton's parakeet, ''Psittacula exsul'' (Rodrigues, Mascarenes, c. 1875)
* Mascarene grey parakeet, ''Psittacula bensoni'' (Mauritius, possible Réunion as ''Psittacula cf bensoni''). Formerly described as Mauritius grey parrot, ''Lophopsittacus bensoni''. Known from a 1602 sketch by Captain Willem van Westzanen and by subfossil bones described by David Thomas Holyoak in 1973. Might have survived to the mid-18th century.
* Mascarene parrot, ''Mascarinus mascarin'' (Réunion and possibly Mauritius, Mascarenes, 1834?)
*:Last known individual was a captive bird which was alive before 1834.
* Broad-billed parrot, ''Lophopsittacus mauritianus'' (Mauritius, Mascarenes, 1680?)
*:May have survived to the late 18th century.
* Rodrigues parrot, ''Necropsittacus rodericanus'' (Rodrigues, Mascarenes, late 18th century)
*:The species ''N. francicus'' is fictional, '' N. borbonicus'' most likely so.
* Glaucous macaw, ''Anodorhynchus glaucus'' (N Argentina, early 20th century)
*:Officially critically endangered due to persistent rumors of wild birds, but probably extinct.
* Cuban macaw, ''Ara tricolor'' (Cuba,late 19th century)
*:A number of related species have been described from the West Indies, but are not based on good evidence. Several prehistoric forms are now known to have existed in the region, however.
* Carolina parakeet, ''Conuropsis carolinensis'' (SE North America, c. 1930?)
*:Although the date of the last captive bird's death in the Cincinnati Zoo, 1918, is generally given as its extinction date, there are convincing reports of some wild populations persisting until later. Two subspecies, ''C. c. carolinensis'' (Carolina parakeet, east and south of the Appalachian range–extinct 1918 or c. 1930) and ''C. c. ludovicianus'' (Louisiana parakeet, west of the Appalachian range–extinct c. 1912).
* Guadeloupe parakeet, ''Aratinga labati'' (Guadeloupe, West Indies, late 18th century)
*:Only known from descriptions, the former existence of this bird is likely for biogeographic reasons and because details as described cannot be referred to known species.
* Martinique amazon, ''Amazona martinica'' (Martinique, West Indies, mid-18th century)
* Guadeloupe amazon, ''Amazona violacea'' (Guadeloupe, West Indies, mid-18th century)
*:These extinct amazon parrots were originally described after travelers' descriptions. Their existence is still controversial.

Cuculiformes

Cuckoos
* Delalande's coua, ''Coua delalandei'' (Madagascar, late 19th century?)
* Saint Helena cuckoo, ''Nannococcyx psix'' (Saint Helena, Atlantic, 18th century)

Falconiformes

Birds of prey
* Guadalupe caracara, ''Caracara lutosa'' (Guadalupe, E Pacific, 1900 or 1903)
* Réunion kestrel, ''Falco duboisi'' (Réunion, Mascarenes, c. 1700)

Strigiformes

Typical owls and barn owls.
* Pernambuco pygmy owl, ''Glaucidium mooreorum'' (Pernambuco, Brazil, 2001?)
*:Might still exist, classified as critically endangered. A 2018 BirdLife study citing extinction patterns recommended reclassifying this species as possibly extinct.
* Réunion scops owl, ''Mascarenotus grucheti'' (Réunion, Mascarenes, late 17th century?)
* Mauritius scops owl, ''Mascarenotus sauzieri'' (Mauritius, Mascarenes, c. 1850)
* Rodrigues scops owl, ''Mascarenotus murivorus'' (Rodrigues, Mascarenes, mid-18th century)
*:The preceding three species were variously placed in ''Bubo'', ''Athene'', ''"Scops"'' (=''Otus''), ''Strix'' and ''Tyto'' before their true affinity was realized.
* New Caledonian boobook, ''Ninox'' cf. ''novaeseelandiae'' (New Caledonia, Melanesia)
*:Known only from prehistoric bones, but might still survive.
* Laughing owl, ''Sceloglaux albifacies'' (New Zealand, 1914?)
*:Two subspecies, ''S. a. albifacies'' (South Island and Stewart Island, extinct 1914?) and ''S. a. rufifacies'' (North Island, extinct c. 1870s?); circumstantial evidence suggests that small remnants survived until the early/mid-20th century.
* The Puerto Rican barn owl, ''Tyto cavatica'', known from prehistoric remains found in caves of Puerto Rico, West Indies; may still have existed in 1912, given reports of the presence of cave-roosting owls.
* The Andros Island barn owl, ''Tyto pollens'', known from prehistoric remains found on Andros (Bahamas); may have survived to the 16th century, as indicated by the "chickcharney" legend.
* Siau scops owl, ''Otus siaoensis'' (20th century?)
*: Only known from the holotype collected in 1866. Endemic to the small volcanic island of Siau north of Sulawesi in Indonesia; might still survive, as there are ongoing rumors of scops owls at Siau.

Caprimulgiformes

Caprimulgidae - nightjars and nighthawks

Reclusive ground-nesting birds that sally out at night to hunt for large insects and similar prey. They are easily located by the males' song, but this is not given all year. Habitat destruction represents currently the biggest threat, while island populations are threatened by introduced mammalian predators, notably dogs, cats, pigs and mongooses.
* Jamaican poorwill, ''Siphonorhis americana'' (Jamaica, West Indies, late 19th century?)
*:Reports of unidentifiable nightjars from the 1980s in habitat appropriate for ''S. americana'' suggest that this cryptic species may still exist. Research into this possibility is currently underway; pending further information, it is classified as critically endangered, possibly extinct.
* Cuban pauraque, ''Siphonorhis daiquiri'' (Cuba, West Indies, prehistoric?)
*:Described from subfossil bones in 1985. There are persistent rumors that this bird, which was never seen alive by scientists, may still survive. Compare Puerto Rican nightjar and preceding.
* Vaurie's nightjar (''Caprimulgus centralasicus'') is only known from a single 1929 specimen from Xinjiang, China. It has never been found again, but the validity of this supposed species is seriously disputed. It was never refuted to be an immature female desert European nightjar.

Apodiformes

Swifts and hummingbirds
* Coppery thorntail, ''Discosura letitiae'' (Bolivia?)

Meliphagidae – honeyeaters and Australian chats
* Chatham bellbird, ''Anthornis melanocephala'' (Chatham Islands, Southwest Pacific, c. 1910)
*:Sometimes regarded as a subspecies of the New Zealand bellbird, ''Anthornis melanura''. Unconfirmed records exist from the early-mid-1950s.
* The identity of ''" Strigiceps leucopogon"'' (an invalid name), described by Lesson in 1840, is unclear. Apart from the holotype supposedly from " New Holland", a second specimen from the "Himalaya" may have existed (or still exist). Lesson tentatively allied it to the Meliphagidae, and Rothschild felt reminded of the kioea.

* Red Sea cliff swallow, ''Petrochelidon perdita'' (Red Sea area, late 20th century?)
*:Known from a single specimen, this enigmatic swallow probably still exists, but the lack of recent records is puzzling. It is alternatively placed in the genus ''Hirundo''.

* Pagan reed warbler, ''Acrocephalus yamashinae'' (Pagan, Marianas, 1970s)
* Garrett's reed warbler, ''Acrocephalus musae'' (Society Islands, 19th century?)
* Moorea reed warbler,'' Acrocephalus longirostris'' (Moorea, Society Islands, 1980s?)
*:Last reliable sighting was in 1981. Survey in 1986/1987 remained unsuccessful. A photograph of a warbler from Moorea in 1998 or 1999 taken by Philippe Bacchet remains uncertain, as do reports from 2003 and 2010.

Muscicapidae – Old World flycatchers and chats
* Rück's blue flycatcher, ''Cyornis ruckii'' (Malaysia or Indochina, 20th century?)
*:An enigmatic bird known from two or four possibly migrant specimens, last recorded in 1918. Might exist in northeast Indochina and might be a subspecies of the Hainan blue flycatcher.

Megaluridae – megalurid warblers or grass warblers
* Chatham fernbird, ''Bowdleria rufescens'' (Chatham Islands, New Zealand, c. 1900)
*:Often placed in genus ''Megalurus'', but this is based on an incomplete review of the evidence.

Cisticolidae – cisticolas and allies
* Tana River cisticola, ''Cisticola restrictus'' (Kenya, 1970s?)
*:A mysterious bird, found in the Tana River basin in small numbers at various dates, but not since 1972. Probably invalid, based on aberrant or hybrid specimens. An unconfirmed sighting was apparently made in 2007 in the Tana River Delta.

Zosteropidae – white-eyes - probably belonging to Timaliidae

* Aldabra brush warbler, ''Nesillas aldabrana'' (Aldabra, Indian Ocean, c. 1984)
* Rodrigues "babbler" (Rodrigues, Mascarenes, 17th century?)

* Pohnpei starling, ''Aplonis pelzelni'' (Pohnpei, Micronesia, c. 2000)
*:Only one reliable record since 1956, in 1995, leaves the species' survival seriously in doubt.
* Bay starling, ''Aplonis? ulietensis'' (Raiatea, Society Islands, between 1774 and 1850)
*:Usually called "bay thrush" (''Turdus ulietensis''); a mysterious bird from Raiatea, now only known from a painting and some descriptions of a (now lost) specimen. Its taxonomic position is thus unresolvable at present, although for biogeographic reasons and because of the surviving description, it has been suggested to have been a honeyeater. However, with the discovery of fossils of the prehistorically extinct starling '' Aplonis diluvialis'' on neighboring Huahine, it seems likely that this bird also belonged to this genus.
* Hoopoe starling, ''Fregilupus varius'' (Réunion, Mascarenes, 1850s)
*:Tentatively assigned to Sturnidae.
* Rodrigues starling, ''Necropsar rodericanus'' (Rodrigues, Mascarenes, mid-18th century?)
*:Tentatively assigned to Sturnidae. The bird variously described as ''Necropsar leguati'' or ''Orphanopsar leguati'' and considered to be identical with ''N. rodericanus'' (which is only known from subfossil bones) was found to be based on a misidentified albinistic specimen of the Martinique trembler (''Cinclocerthia gutturalis'')

Three subspecies are known from Oahu ('' M. l. woahensis'', extinct 1850s), Lanaʻi (''M. l. lanaiensis'', extinct early 1930s), Molokaʻi (''M. l. rutha'', extinct 1980s?) and a possible fourth subspecies from Maui (extinct before late 19th century).

Mimidae – mockingbirds and thrashers
*Cozumel thrasher, ''Toxostoma guttatum'' (Cozumel, Caribbean, early first decade of the 21st century?)
*:It is still unknown whether the tiny population rediscovered in 2004 survived Hurricanes Emily and Wilma in 2005. Unconfirmed records in April 2006 and October and December 2007.

* Bermuda towhee, ''Pipilo naufragus''. Known by subfossil remains and possibly from a travel report by William Strachey in 1610.

Possibly extinct bird subspecies or status unknown

Extinction of subspecies is a subject very dependent on guesswork. National and international conservation projects and research publications such as redlists usually focus on species as a whole. Reliable information on the status of threatened subspecies usually has to be assembled piecemeal from published observations, such as regional checklists. Therefore, the following listing contains a high proportion of taxa that may still exist, but are listed here due to any combination of absence of recent records, a known threat such as habitat destruction, or an observed decline.

Struthioniformes

Ratites and related birds

* Arabian ostrich, ''Struthio camelus syriacus'' (Arabia, 1966)
:The last record of this ostrich subspecies was a bird found dead in Jordan in 1966.

Apterygiformes

* North Island little spotted kiwi, ''Apteryx owenii iredalei'' (North Island, New Zealand, late 19th century)
:A doubtfully distinct little spotted kiwi subspecies.

Casuariiformes

*King Island emu, ''Dromaius novaehollandiae minor'' (King Island, Australia, 1822)

*Kangaroo Island emu, ''Dromaius novaehollandiae baudinianus'' (Kangaroo Island, Australia, 1827)
:A dwarf subspecies of the emu; extinct since c. 1827.
*Tasmanian emu, ''Dromaius novaehollandiae diemenensis'' (Tasmania, Australia, mid-19th century)
:A dwarf subspecies of the emu; the last wild bird was collected in 1845. It may have persisted in captivity until 1884. It may be invalid.

Tinamiformes

Tinamous
* Magdalena tinamou, ''Crypturellus (erythropus) saltuarius'' (Colombia, late 20th century?)
:Variously considered a red-legged tinamou subspecies or a distinct species, this bird is currently only known with certainty from the 1943 type specimen. An additional specimen exists (or existed), but its present whereabouts is unknown. Recent research suggest that it is still extant and there was a likely – although as yet unconfirmed – record near the type locality by Colombian ornithologist Oswaldo Cortés in late 2008.

Anseriformes

Ducks, geese and swans
* Bering cackling goose, ''Branta hutchinsii asiatica'' (Komandorski and Kuril Islands, N Pacific, c. 1914 or 1929)

* Pink-headed duck, ''Rhodonessa caryophyllacea'' (East India, Bangladesh, North Myanmar, 1945?)– a reclassification into the genus ''Netta'' is recommended, but not generally accepted.
*:Officially critically endangered; recent surveys have failed to rediscover it, though sightings continue to be reported.
:A doubtfully distinct subspecies of the Sunda teal, which disappeared due to predation on young birds by introduced tilapia (''Oreochromis mossambicus'').
* Niceforo's pintail, ''Anas georgica niceforoi'' (Colombia, 1950s)

* Coues' gadwall, ''Anas strepera couesi'' (Teraina, Kiribati, c.1900)
:This island subspecies of the gadwall was discovered in 1874 and has not been recorded since, with none found by a 1924 expedition from Honolulu's Bishop Museum.

Galliformes

Quails and relatives
* Italian grey partridge, ''Perdix perdix italica'' (Italy, 1980s)
:A subspecies of the grey partridge whose validity has been questioned; the last purebred individuals disappeared during the late 1980s due to hybridization with introduced birds.

:A subspecies of the helmeted guineafowl. Reportedly still kept in captivity in Morocco in the late 1990s. Possibly extinct in the wild by 1950, three records from the 1970s may refer to feral-domestic hybrids.

Charadriiformes

Shorebirds, gulls and auks
* Kiritimati sandpiper, ''Prosobonia cancellata cancellata'' (Kiritimati, Kiribati, 19th century?)
:The doubtfully distinct nominate subspecies of the Tuamotu sandpiper, sometimes considered a distinct species, but only known from a painting.
* Andalusian hemipode, ''Turnix sylvatica sylvatica'' (Mediterranean region, extant)
:The nominate subspecies of the small buttonquail has been considered likely extinct, having last been recorded in Spain in 1981. However, it was confirmed extant with the discovery of a population in Morocco in 2007.
* Tawitawi small buttonquail, ''Turnix sylvatica suluensis'' (Tawitawi, Philippines, mid-20th century?)
:A small buttonquail subspecies. It has not been recorded since the 1950s, but there have been few surveys and it is likely to persist.
* New Caledonia painted buttonquail, ''Turnix varius novaecaledoniae'' (New Caledonia, Melanesia, early 20th century?)
:A subspecies of the painted buttonquail that has been variously considered anything from a hybrid between introduced species to a full species. Plentiful subfossil bones indicate that it was indeed a good endemic form. The last specimen was taken in 1912 and surveys since have failed to record it.

Gruiformes

Rails and allies - probably paraphyletic
* Goldman's yellow rail, ''Coturnicops noveboracensis goldmani'' (Mexico, late 20th century?)

:Buff-banded rail subspecies.
* Raoul Island banded rail, ''Gallirallus philippensis'' ssp. (Raoul, Kermadec Islands, southwest Pacific, late 19th century?)
:Reports of the former occurrence of the species on Raoul seem plausible enough, but they may relate to vagrant individuals of another buff-banded rail subspecies.
* Peruvian rail, ''Rallus semiplumbeus peruvianus'' (Peru, 20th century?)
:A subspecies of the Bogota rail which is known from a single specimen collected in the 1880s. It may still be extant.
* Western Lewin's rail, ''Lewinia pectoralis clelandi'' (SW Australia, late 1930s?)
:A subspecies of Lewin's rail not recorded since 1932 despite multiple surveys in the late 20th century.
* Assumption white-throated rail, ''Dryolimnas cuvieri abbotti'' (Assumption, Astove and Cosmoledo, Aldabra Islands, early 20th century)
:A white-throated rail subspecies.
* Jamaican uniform crake, ''Amaurolimnas concolor concolor'' (Jamaica, West Indies, late 19th century)

:A subspecies of the Arabian bustard. Last observed in 1993 at Lac Merzouga/Lac Tamezguidat.
* Luzon sarus crane, ''Antigone antigone luzonica'' (Luzon, Philippines, late 1960s)
:A subspecies of the sarus crane which is not always accepted as valid, possibly because the existing specimens have not been thoroughly studied since it was described.

Ciconiiformes

Herons and related birds - possibly paraphyletic
* Bonin nankeen night heron, ''Nycticorax caledonicus crassirostris'' (Nakoudo-jima and Chichi-jima, Ogasawara Islands, c. 1890)
:A nankeen night heron subspecies.
* Principe olive ibis, ''Bostrychia olivacea rothschildi'' (Principe, Gulf of Guinea, extant)
:A subspecies of the olive ibis or (as ''B. bocagei rothschildi'') the São Tomé ibis if this is considered a distinct species. It was unrecorded through most of the 20th century and has been considered extinct, but was recorded on multiple occasions in the 1990s and should now be considered extant.

Pterocliformes

Sandgrouse
*Fayyum sandgrouse, ''Pterocles exustus floweri'' (Fayyum area, Egypt, late 20th century?)
:This subspecies of the chestnut-bellied sandgrouse was last recorded in 1979 and is likely to have gone extinct since.

Columbiformes

Pigeons, doves and dodos
* Madeiran wood pigeon, ''Columba palumbus maderensis'' (Madeira, East Atlantic, early 20th century)
:A subspecies of the wood pigeon.
* Ogasawara Japanese wood pigeon, ''Columba janthina nitens'' (Ogasawara Islands, Northwest Pacific, extant)
:Japanese wood pigeon subspecies thought to have gone extinct in the 1980s, but there have been recent reports and photographs and the taxon is now considered extant, though very rare.
* Lord Howe pigeon, ''Columba vitiensis godmanae'' (Lord Howe Island, Southwest Pacific, 1853)
: Metallic pigeon subspecies last recorded in 1853 and almost certainly extinct by 1869.
* Tongan metallic pigeon, ''Columba vitiensis'' ssp. (Vava'u, Tonga, late 18th century?)
:This subspecies of the metallic pigeon is only known from a footnote in John Latham's ''General History of Birds'' and seems to have died out some time before 1800; possibly, the location is erroneous and the note really refers to the extant population on Fiji.
*Amirante turtle-dove, ''Nesoenas picturata aldabrana'' (Amirante Islands, Seychelles, late 20th century)
:This subspecies of the Malagasy turtle dove persisted until at least 1974, after which it was hybridised out of existence through breeding with the introduced nominate subspecies.
* Catanduanes bleeding-heart, ''Gallicolumba luzonica rubiventris'' (Catanduanes, Philippines, late 20th century?)
:A subspecies of the Luzon bleeding-heart known from a single specimen collected in 1971. There have been recent reports of the taxon and, as much of its forest habitat remains, it is likely to be extant.
* Basilan bleeding-heart, ''Gallicolumba crinigera bartletti'' (Basilan, Philippines, mid-20th century?)
:A subspecies of the Mindanao bleeding-heart, it was last reported in 1925 and given the massive habitat destruction is likely extinct.
* Vella Lavella ground dove, ''Gallicolumba jobiensis chalconota'' (Vella Lavella, Makira and Guadalcanal, Solomon Islands, late 20th century?)
:A subspecies of the white-breasted ground dove or possibly a distinct species. Known from only four specimens, there are no recent records and the local population report it has disappeared.
* White-headed Polynesian ground dove, ''Gallicolumba erythroptera albicollis'' (Central Tuamotu Islands, 20th century?)
:The Central Tuamotu subspecies of the Polynesian ground dove, often referred to as ''G. e. pectoralis'', disappeared at an undetermined date, but might still exist on some unsurveyed atolls. The identity of northern Tuamotu populations, possibly still extant, is undetermined.
* Ebon crimson-crowned fruit dove, ''Ptilinopus porphyraceus marshallianus'' (Ebon?, Marshall Islands, late 19th century?)
:Crimson-crowned fruit dove subspecies of doubtful validity. Known from a single specimen collected in 1859; it is not certain whether this bird actually occurred on Ebon. All that can be said is that this subspecies is no longer found anywhere.
* Mauke fruit dove, ''Ptilinopus rarotongensis "byronensis"'' (Mauke, Cook Islands, mid- or late 19th century)
:A subspecies of the lilac-crowned fruit dove, known only from the description of a now-lost specimen. The prehistorically extinct population on Mangaia is likely to belong to another distinct subspecies too.
* Negros spotted imperial pigeon, ''Ducula carola nigrorum'' (Negros and probably Siquijor, late 20th century?)
: Spotted imperial pigeon subspecies not recorded since the 1950s.
* Norfolk pigeon, ''Hemiphaga novaeseelandiae spadicea'' (Norfolk Island, Southwest Pacific, early 20th century)
:A subspecies of the New Zealand pigeon not recorded since 1900. Similar birds were reported from Lord Howe Island; these seem to represent another extinct subspecies, but are undescribed to date.
* Raoul Island kereru, ''Hemiphaga novaeseelandiae'' ssp. nov. (Raoul, Kermadec Islands, 19th century)
:Another undescribed subspecies (or possibly species) of the New Zealand pigeon, known from bones and a brief report.

* Challenger's lory, ''Eos histrio challengeri'' (Nenusa Islands, Talaud Archipelago, early 20th century?)
:A supposed subspecies of the red and blue lory, but probably invalid.
* Macquarie parakeet, ''Cyanoramphus novaezelandiae erythrotis'' (Macquarie Islands, SW Pacific, 1890s)
:Red-crowned parakeet subspecies last recorded in 1890 and not found by surveys in 1894.
* Lord Howe parakeet, ''Cyanoramphus novaezelandiae subflavescens'' (Lord Howe Island, SW Pacific, c. 1870)
:Red-crowned parakeet subspecies.
* Réunion parakeet, ''Psittacula eques eques'' (Réunion, Mascarenes, mid-18th century)
:Known only from a painting and descriptions; if it is accepted as valid, it would become the nominate subspecies of the Mauritius parakeet, extant on Mauritius, which would then have to be called ''P. eques echo''.
* Siquijor colasisi, ''Loriculus philippensis siquijorensis'' (Siquijor, Philippines, 20th century?)
:A subspecies of the colasisi or Philippine hanging parrot, either very rare or already extinct.

:A weakly differentiated subspecies of the Hispaniolan parakeet.
* Sinú brown-throated parakeet, ''Aratinga pertinax griseipecta'' (Colombia, mid- or late 20th century?)
:A subspecies of the brown-throated parakeet known from only two specimens collected in 1949 and of unclear taxonomical and conservation status.
* Culebra amazon, ''Amazona vittata gracilipes'' (Culebra, West Indies, early 20th century)
:A weakly differentiated subspecies of the Puerto Rican amazon, which is itself highly endangered.

Cuculiformes

Cuckoos
* Greater crested coua, ''Coua cristata maxima'' (SE Madagascar, late 20th century?)
:Crested coua subspecies, known only from a single specimen taken in 1950. It may be a hybrid, but if not it is probably extinct.
* Assumption Island coucal, ''Centropus toulou assumptionis'' (Assumption Island, Seychelles, early 20th century)
:A Madagascar coucal subspecies last recorded in 1906. It is often considered synonymous with the Aldabra form ''insularis'', which has since recolonized Assumption Island.
* Cabo San Lucas groove-billed ani, ''Crotophaga sulcirostris pallidula'' (Mexico, c. 1940)
:A weakly differentiated and probably invalid subspecies of the groove-billed ani.
* Bahia rufous-vented ground cuckoo, ''Neomorphus geoffroyi maximiliani'' (E Brazil, mid-20th century?)
:Rufous-vented ground cuckoo subspecies.

Falconiformes

Birds of prey
* Cape Verde kite, ''Milvus ''(''milvus'')'' fasciicauda'' (Cape Verde Islands, E Atlantic, 2000)
:Considered either a subspecies of the red kite, a distinct species, or a hybrid between red and black kites, the validity of this taxon has recently been questioned on the basis of molecular analysis. However, hybridization and a confusing molecular phylogeny of red kite populations, coupled with the distinct phenotype of the Cape Verde birds, suggest that the taxonomic status of this form is far from resolved.
* Car Nicobar sparrowhawk, ''Accipiter butleri butleri'' (Car Nicobar, Nicobar Islands, 20th century?)
: The nominate subspecies of the Nicobar sparrowhawk– which is currently listed as vulnerable– is possibly extinct. It was last reliably recorded in 1901 and despite searches, has not been sighted after an unconfirmed record in 1977. However, the species is known for being very shy and a population may persist unrecorded.
* Volcano Islands peregrine falcon, ''Falco peregrinus furuitii''. (Ogasawara Islands, 1940s)
:Peregrine falcon subspecies from the Ogasawara Islands. No sightings since 1945. A survey in 1982 failed to find this bird. Only known from Iwo Jima and Torishima.

Strigiformes

Typical owls and barn owls
* Sulu reddish scops owl, ''Otus rufescens burbidgei'' (Sulu, Philippines, mid-20th century)
:A subspecies of the reddish scops owl. Known from a single questionable specimen and may not be valid.
* Virgin Islands owl or Virgin Islands screech owl, ''Gymnasio nudipes newtoni'' (Virgin Islands, Caribbean, 20th century?)
:A subspecies of the Puerto Rican owl, of somewhat doubtful validity, which occurred on several of the Virgin Islands, West Indies. The last reliable records are in 1860; there were a number of unconfirmed reports during the 20th century, but it was not found in thorough surveys in 1995.
* Socorro elf owl, ''Micrathene whitneyi graysoni'' (Socorro, Revillagigedo Islands, mid-20th century?)
:A subspecies of the elf owl. Officially listed as critically endangered, the last specimen was taken in 1932, but there was apparently still a large population in 1958; it was not found by subsequent searches and it appears to be extinct.
* Antiguan burrowing owl, ''Athene cunicularia amaura'' (Antigua, St Kitts and Nevis, West Indies, c. 1900)
:Burrowing owl subspecies, last collected in 1890 and extinct by 1903.

* Lord Howe boobook, ''Ninox novaeseelandiae albaria'' (Lord Howe Island, Southwest Pacific, 1950s)
:Southern boobook subspecies last recorded in the 1950s.
* Norfolk boobook, ''Ninox novaeseelandiae undulata'' (Norfolk Island, Southwest Pacific, 1990s)
:Individuals of the nominate subspecies were introduced in a last-ditch effort to save the local owl population. There now exists a hybrid population of a few dozen birds; the last individual of ''N. n. undulata'', a female named ''Miamiti'', died in 1996, though individuals descended from her remain.
* Cave-nesting masked owl, ''Tyto novaehollandiae troughtoni'' (Nullarbor Plain, Australia, 1960s)
:Doubtfully distinct from nominate subspecies, but differed behaviorally.
* Buru masked owl, ''Tyto sororcula cayelii'' (Buru, Indonesia, mid-20th century?)
:Subspecies of the lesser masked owl. Last recorded in 1921; the identity of a similar bird found on Seram remains to be determined. Seems to survive, as an owl matching this bird's description was encountered in August 2006.
* Peleng masked owl, ''Tyto rosenbergii pelengensis'' (Peleng, Banggai Islands, mid-20th century)
:Subspecies of the Sulawesi owl or a separate species. Possibly extant, but the only specimen known was taken in 1938 and there have been no further records.
* Samar bay owl, ''Phodilus badius riverae'' (Samar, Philippines, mid-20th century)
:Subspecies of the Oriental bay owl or a possibly distinct species. Taxonomy doubtful, but only specimen lost in 1945 bombing raid, so validity cannot be verified; no population exists on Samar today.

Caprimulgiformes

Nightjars and allies
* New Caledonian white-throated nightjar, ''Eurostopodus mystacalis exsul'' (New Caledonia, Melanesia, mid-20th century)
:This distinct subspecies of the white-throated nightjar is possibly a separate species. It was found only once; due to its cryptic habits, it possibly still exists, but this is now considered unlikely.

Apodiformes

Swifts and hummingbirds
* Miravalles hummingbird, ''Amazilia cyanifrons alfaroana'' (Costa Rica, Central America, 20th century?)
:This subspecies of the indigo-capped hummingbird is only known from a specimen collected in Costa Rica in 1895. It is likely to have gone extinct since
* Alejandro Selkirk firecrown, ''Sephanoides fernandensis leyboldi'' (Alejandro Selkirk Island, Juan Fernández Islands, Southeast Pacific, 1908)
:Juan Fernández firecrown subspecies last recorded in 1908.
* Luzon Whitehead's swiftlet, ''Collocalia whiteheadi whiteheadi'' (Luzon, Philippines, 20th century?)
:The nominate subspecies of Whitehead's swiftlet is only known from four specimens collected at Mount Data in 1895. From the lack of further records and the massive habitat destruction, it is usually considered extinct. Given the size of the island, it might still exist though.

Coraciiformes

Kingfishers and related birds
* Sangihe dwarf kingfisher, ''Ceyx fallax sangirensis'' ( Sangihe, Indonesia, 1998?)
:This subspecies of the Sulawesi dwarf kingfisher was last seen in 1997 but not during a thorough survey one year later; it is either close to extinction or already extinct. Sometimes it is said to occur on Talaud Islands also, but this is erroneous.
* Rarotonga kingfisher, ''Todiramphus'' cf. ''tutus'' (Rarotonga, Cook Islands, mid-1980s?)
:There exist reports of locals that kingfishers–probably a subspecies of the chattering kingfisher which is found on neighboring islands, but possibly vagrants from there–were found until around 1979 and there is a last record from 1984. Presently, no kingfishers are known to exist on Rarotonga.
* Mangareva kingfisher, ''Todiramphus gambieri gambieri'' (Mangareva, Gambier Islands, late 19th century)
:Only known from a single 1844 specimen, the nominate subspecies of the Tuamotu kingfisher was not found again when it was next searched for in 1922.
*Guam kingfisher, ''Todiramphus cinnamominus cinnamominus'' (Guam, West Pacific, 1986)
:This subspecies of the Micronesian kingfisher became extinct in the wild in 1986 when 29 birds were taken for a captive breeding programme, which is ongoing. Its decline was caused by the depredations of introduced brown tree snakes.
* Ryūkyū kingfisher, ''Todiramphus cinnamominus miyakoensis'' (Miyako-jima, Ryukyu Islands, late 19th century)
:Previously considered as a full species, but better regarded as a subspecies of the Micronesian kingfisher (''Todiramphus cinnamominus''). Only seen once by scientists, in 1887; the specimen taken is somewhat damaged, making identification by other than molecular analysis difficult. It is now thought likely that the specimen came from Guam, where the nominate subspecies was distributed, rather than Miyako, which would make this subspecies invalid.
* Javan blue-banded kingfisher, ''Alcedo euryzona euryzona'' (Java, Indonesia, extant)
:The nominate subspecies of the blue-banded kingfisher; the last specimen was taken in 1937 and the taxon has been considered extinct, but it was mist-netted five times in 2000-2001 at Halimun National Park, which has not undergone much change since.
* Guadalcanal little kingfisher, ''Alcedo pusilla aolae'' (Guadalcanal, Solomon Islands, ?)
:Little kingfisher subspecies.
* Sakarha pygmy kingfisher, ''Ispidina madagascariensis dilutus'' (Southwest Madagascar, late 20th century?)
:This subspecies of the Madagascar pygmy kingfisher is only known from one specimen taken in 1974 in an area where most habitat had already been lost. However, there have been records of the species (uncertain subspecies) from near the type locality, suggesting it is likely to be extant.
* Ticao hornbill, ''Penelopides panini ticaensis'' (Ticao, Philippines, 1970s)
:A subspecies of the Visayan hornbill of somewhat uncertain status–possibly a distinct species, possibly a color morph–the last confirmed report was in 1971 and it became extinct shortly thereafter.

* Grand Bahama West Indian woodpecker, ''Melanerpes superciliaris bahamensis'' (Grand Bahama, Bahamas, 1950s)
:A West Indian woodpecker subspecies of somewhat uncertain validity.
* Javan buff-rumped woodpecker, ''Meiglyptes tristis tristis'' (Java, Indonesia, c. 1920?)
:The nominate subspecies of the buff-rumped woodpecker became rare during the 19th century due to destruction of habitat. The last confirmed record was in 1880, and it is now considered at least very rare.
* Guadalupe red-shafted flicker, ''Colaptes auratus rufipileus'' (Guadalupe, East Pacific, c. 1910)
:A subspecies of the northern flicker (or the red-shafted flicker, as ''C. cafer rufipileus''), it was last recorded in 1906 and not found again in both 1911 and 1922. It may be invalid. Recently, vagrant birds of a mainland red-shafted subspecies have begun recolonizing the island as the habitat improves after the removal of feral goats.
* Northern white-mantled barbet, ''Capito hypoleucus hypoleucus'' (Colombia, extant)
:The nominate subspecies of the white-mantled barbet has been considered extinct, but has been recorded recently.
* Botero white-mantled barbet, ''Capito hypoleucus carrikeri'' (Colombia, extant)
:Another subspecies of the white-mantled barbet, also considered extinct by some sources, but confirmed extant by researchers in Colombia.
* Todd's jacamar, ''Brachygalba lugubris phaeonota'' (Brazil, late 20th century?)
:A subspecies of the brown jacamar, or possibly a hybrid, color morph or full species. Might survive, as it is only known from a remote and seldom-visited area.
* Cebu white-bellied woodpecker, ''Dryocopus javensis cebuensis'' (Cebu, Philippines, 20th century)
:Only known by three specimens collected before 1900.

Passeriformes

Furnariidae – ovenbirds
* Peruvian scale-throated earthcreeper, ''Upucerthia dumetaria peruana'' (Peru, 20th century?)
:A subspecies of the scale-throated earthcreeper, it is only known from two specimens taken in the early 1950s at Puno, Peru, and has never been found since. It may well persist, as there is no obvious reason why it should have become extinct.
* Northern stripe-crowned spinetail, ''Cranioleuca pyrrhophia rufipennis'' (N Bolivia, 20th century?)
:A stripe-crowned spinetail subspecies known from a few specimens and not recorded since the 1950s; may be endangered or possibly extinct.

Formicariidae – antpittas and antthrushes
* Northern giant antpitta, ''Grallaria gigantea lehmanni'' (Colombia, 20th century?)
:A giant antpitta (or possibly great antpitta) subspecies apparently not recorded since the 1940s. Might still survive in Puracé National Natural Park, where there is plentiful habitat remaining.
* Antioquia brown-banded antpitta, ''Grallaria milleri gilesi'' (Antioquia, Colombia, 20th century?)
:A brown-banded antpitta subspecies recently described from a specimen collected in 1878. It has not been recorded since, despite surveys at a number of likely locations.

:A brown thornbill subspecies which has only been recorded c.10 times since its discovery and considered extinct by some sources. The latest record comes from 2002, suggesting a population is likely to be extant, but very rare.

PetroicidaeAustralasian "robins"
* Tiwi Island hooded robin, ''Melanodryas cucullata melvillensis'' (Tiwi Islands, Australia, 1992)
:Subspecies of the hooded robin, last observed in 1992 and not found in exhaustive searches later in the 1990s.

Cinclosomatidae – whipbirds and allies
* Mount Lofty spotted quail-thrush, ''Cinclosoma punctatum anachoreta'' (Australia, mid-1980s?)
:A subspecies of the spotted quail-thrush, last recorded in 1983 and not found in a survey the following year.

Artamidae – woodswallows, currawongs and allies
* Western pied currawong, ''Strepera graculina ashbyi'' (Victoria, Australia, 1927)
:This pied currawong subspecies has been swamped by other subspecies, which probably came into contact following habitat destruction in the 1830s. The last certainly distinct individuals were recorded in 1927.

Monarchidae – monarch flycatchers
* Negros celestial monarch, ''Hypothymis coelestis rabori'' (Negros and possibly Sibuyan, Philippines, late 20th century?)

* Cebu bar-bellied cuckoo-shrike, ''Coracina striata cebuensis'' (Cebu, Philippines, early 20th century)
: Bar-bellied cuckoo-shrike subspecies not recorded since its collection in 1906.
* Maros cicadabird, ''Coracina tenuirostris edithae'' (Sulawesi, mid-20th century)
:A subspecies of the cicadabird known from a single specimen collected in 1931; quite possibly just a vagrant individual.
* Cebu blackish cuckoo-shrike, ''Coracina coerulescens altera'' (Cebu, Philippines, 20th century?)
:A blackish cuckoo-shrike subspecies; could be extant as the birds are rather unmistakable and a 1999 record therefore likely to be valid, though surveys since then have failed to find it
* Marinduque blackish cuckoo-shrike, ''Coracina coerulescens deschauenseei'' (Marinduque, Philippines, late 20th century?)
:Another blackish cuckoo-shrike subspecies, described from specimens collected in 1971, but apparently not seen since. As few ornithologists have visited Marinduque and forest remains on the island, it is thought likely to remain extant.
* Norfolk long-tailed triller, ''Lalage leucopyga leucopyga'' (Norfolk Island, Southwest Pacific, 1942)
:A subspecies of the long-tailed triller, possibly a distinct species.

Oriolidae – orioles and figbird
* Cebu dark-throated oriole, ''Oriolus xanthonotus assimilis'' (Cebu, Philippines, 20th century?)

* Western Turner's eremomela, ''Eremomela turneri kalindei'' (Congo Basin, late 20th century?)
:The West African subspecies of Turner's eremomela has not been recorded since the end of the 1970s, but there is unsurveyed habitat in its range where it is likely to survive. Placement in Cettiidae requires confirmation.

Acrocephalidae – acrocephalid warblers or marsh- and tree warblers
* Marshall Islands reed warbler, ''Acrocephalus rehsei'' ssp.? (Marshall Islands, Micronesia, c.1880?)
:Oral tradition and some early reports mention a bird called ''annañ'' which inhabited some of the Marshall Islands. The best match is the Nauru reed warbler; the ''annañ'' might have been an undescribed subspecies of that species, or a distant but related species of reed warbler.
* Laysan millerbird, ''Acrocephalus familiaris familiaris'' (Laysan Island, Hawaiian Islands, late 1910s)
:The millerbird's nominate subspecies.
* Huahine Polynesian warbler, ''Acrocephalus caffer garretti'' (Huahine, Society Islands, c.1900)

* Mukojima white-eye, ''Apalopteron familiare familiare'' (Mukojima Group, Ogasawara Islands, 20th century?)
:Bonin white-eye ("Bonin honeyeater") subspecies not recorded since its last specimen was collected in 1930.

Timaliidae – Old World babblers
* Vanderbilt's babbler, ''Malacocincla sepiarium vanderbilti'' (Sumatra, Indonesia, late 20th century?)
:An enigmatic subspecies of Horsfield's babbler, known from a single specimen. Not seen since the 1940s at the latest.
* Burmese Jerdon's babbler, ''Chrysomma altirostre altirostre'' (Myanmar, 20th century?)
:The nominate subspecies of Jerdon's babbler was last confirmed in 1941, but as there has been little fieldwork in its range and a possible sighting in 1994, it is considered likely to persist.

"African warblers"
* Chapin's crombec, ''Sylvietta leucophrys chapini'' (Congo Basin, late 20th century?)
:A subspecies of the white-browed crombec, sometimes listed as a separate species. Restricted to the Lendu Plateau, it is probably rare, though unsurveyed forest remains where it is likely to persist.

Sylvioidea ''incertae sedis''
* Lake Amik bearded reedling, ''Panurus biarmicus kosswigi'' (S Turkey, extant)
:Bearded reedling subspecies, which has been considered extinct owing to the drainage of Lake Amik, but is still extant in the area.

* Guadalupe Bewick's wren, ''Thryomanes bewickii brevicauda'' (Guadalupe, East Pacific, late 1890s?)
:Bewick's wren subspecies. An extinction date of "1903" seems to be in error; the last unquestionable record dates from 1897 and a thorough search in 1901 failed to find it.
* San Clemente Bewick's wren, ''Thryomanes bewickii leucophrys'' (San Clemente, East Pacific, 1941)
:Another Bewick's wren subspecies, last recorded in 1941.
* Daito wren, ''Troglodytes troglodytes orii'' (Daito Islands, Northwest Pacific, c. 1940)

* Lifou thrush, ''Turdus poliocephalus pritzbueri'' (Lifou, Melanesia, extant)
:Yet another subspecies of the island thrush. birds surviving on Tanna, New Hebrides, are presently considered the same subspecies. However, given the fact that the species readily differentiates into subspecies and that the distance between Tanna and Lifou is considerable, these birds may belong to a different subspecies, in which case the Lifou thrush would be considered extinct.
* Peleng red-and-black thrush, ''Zoothera mendeni mendeni'' (Peleng, Indonesia, mid-20th century?)
