Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the ...

pelicans formed one lineage, with the American white pelican sister to the two brown pelicans, and the five Old World species the other. The Dalmatian, pink-backed, and spot-billed were all closely related to one another, while the Australian white pelican was their next-closest relative. The great white pelican also belonged to this lineage, but was the first to diverge from the common ancestor of the other four species. This finding suggests that pelicans evolved in the Old World and spread into the Americas, and that preference for tree- or ground-nesting is more related to size than genetics.

Pelicans are very large birds with very long bills characterised by a downcurved hook at the end of the upper mandible, and the attachment of a huge gular

pouch to the lower. The slender rami of the lower bill and the flexible tongue muscles form the pouch into a basket for catching fish, and sometimes rainwater,[ though to not hinder the swallowing of large fish, the tongue itself is tiny. They have a long neck and short stout legs with large, fully webbed feet. Although they are among the heaviest of flying birds, they are relatively light for their apparent bulk because of air pockets in the skeleton and beneath the skin, enabling them to float high in the water.][ The tail is short and square. The wings are long and broad, suitably shaped for soaring and gliding flight, and have the unusually large number of 30 to 35 secondary ]flight feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail ...

The largest is believed to be the Dalmatian, at up to and in length, with a maximum wingspan of . The Australian pelican's bill may grow up to long in large males,] the longest of any bird.[
Pelicans have mainly light-coloured plumage, the exceptions being the brown and Peruvian pelicans.][ The bills, pouches, and bare facial skin of all species become brighter before breeding season commences.][ The throat pouch of the Californian subspecies of the brown pelican turns bright red, and fades to yellow after the eggs are laid, while the throat pouch of the Peruvian pelican turns blue. The American white pelican grows a prominent knob on its bill that is shed once females have laid eggs.] The plumage of immature pelicans is darker than that of adults. Newly hatched chicks are naked and pink, darkening to grey or black after 4 to 14 days, then developing a covering of white or grey down.[

Air sacs
Anatomical dissections of two brown pelicans in 1939 showed that pelicans have a network of air sacs
Air sacs are spaces within an organism where there is the constant presence of air. Among modern animals, birds possess the most air sacs (9–11), with their extinct dinosaurian relatives showing a great increase in the pneumatization (presence ...
under their skin situated across the ventral surface including the throat, breast, and undersides of the wings, as well as having air sacs in their bones. The air sacs are connected to the airways of the respiratory system, and the pelican can keep its air sacs inflated by closing its glottis
The glottis is the opening between the vocal folds (the rima glottidis). The glottis is crucial in producing vowels and voiced consonants.
Etymology
From Ancient Greek ''γλωττίς'' (glōttís), derived from ''γλῶττα'' (glôtta), va ...
, but how air sacs are inflated is not clear. The air sacs serve to keep the pelican remarkably buoyant in the water and may also cushion the impact of the pelican's body on the water surface when they dive from flight into water to catch fish. Superficial air sacs may also help to round body contours (especially over the abdomen, where surface protuberances may be caused by viscera changing size and position) to enable the overlying feathers to form more effective heat insulation and also to enable feathers to be held in position for good aerodynamics.
Distribution and habitat
Modern pelicans are found on all continents except Antarctica. They primarily inhabit warm regions, although breeding ranges extend to latitudes of 45° South (Australian pelicans in Tasmania

and nest colonially. Pairs are monogamous for a single season, but the pair bond extends only to the nesting area; mates are independent away from the nest. The ground-nesting (white) species have a complex communal courtship involving a group of males chasing a single female in the air, on land, or in the water while pointing, gaping, and thrusting their bills at each other. They can finish the process in a day. The tree-nesting species have a simpler process in which perched males advertise for females.[ The location of the breeding colony is constrained by the availability of an ample supply of fish to eat, although pelicans can use thermals to soar and commute for hundreds of kilometres daily to fetch food.][

s and provide large amounts of food for several months before drying out again.
In all species, copulation takes place at the nest site; it begins shortly after pairing and continues for 3–10 days before egg-laying. The male brings the nesting material, in ground-nesting species (which may not build a nest) sometimes in the pouch, and in tree-nesting species crosswise in the bill. The female then heaps the material up to form a simple structure.[
The eggs are oval, white, and coarsely textured.][ All species normally lay at least two eggs; the usual clutch size is one to three, rarely up to six.][ Both sexes incubate with the eggs on top of or below the feet; they may display when changing shifts.

Small chicks are fed by regurgitation; after about a week, they are able to put their heads into their parents' pouches and feed themselves.

Parents of ground-nesting species sometimes drag older young around roughly by the head before feeding them. From about 25 days old,][ the young of these species gather in "pods" or " crèches" of up to 100 birds in which parents recognise and feed only their own offspring. By 6–8 weeks they wander around, occasionally swimming, and may practise communal feeding.][ Young of all species ]fledge

s, birds, and mammals are also eaten.[Elliott (1992), p. 295-298, 309–311] The size of the preferred prey fish varies depending on pelican species and location. For example, in Africa, the pink-backed pelican generally takes fish ranging in size from fry up to and the great white pelican prefers somewhat larger fish, up to , but in Europe, the latter species has been recorded taking fish up to . In deep water, white pelicans often fish alone. Nearer the shore, several encircle schools of small fish or form a line to drive them into the shallows, beating their wings on the water surface and then scooping up the prey. Although all pelican species may feed in groups or alone, the Dalmatian, pink-backed, and spot-billed pelicans are the only ones to prefer solitary feeding. When fishing in groups, all pelican species have been known to work together to catch their prey, and Dalmatian pelicans may even cooperate with great cormorant

Cannibalism (zoology), Cannibalism of chicks of their own species is known from the Australian, brown, and Peruvian pelicans.[ Great white pelicans have been observed swallowing city pigeons in St. James's Park in London.] Spokeswoman for the Royal Parks, Louise Wood, stated that feeding on other birds is more likely with captive pelicans that live in a semi-urban environment and are in constant close contact with humans.
Status and conservation
Populations
Globally, pelican populations are adversely affected by these main factors: declining supplies of fish through overfishing or water pollution, destruction of habitat, direct effects of human activity such as disturbance at nesting colonies, hunting and culling, entanglement in fishing lines and hooks, and the presence of pollutants such as DDT and endrin. Most species' populations are more or less stable, although three are classified by the IUCN as being at risk. All species breed readily in zoos, which is potentially useful for conservation management.
The combined population of brown and Peruvian pelicans is estimated at 650,000 birds, with around 250,000 in the United States and Caribbean, and 400,000 in Peru. The National Audubon Society estimates the global population of the brown pelican at 300,000. Numbers of brown pelican plummeted in the 1950s and 1960s, largely as a consequence of environmental DDT pollution, and the species was listed as endangered in the US in 1970. With restrictions on DDT use in the US from 1972, its population has recovered, and it was delisted in 2009.
The Peruvian pelican is listed as near threatened because, although the population is estimated by BirdLife International to exceed 500,000 mature individuals, and is possibly increasing, it has been much higher in the past. It declined dramatically during the 1998 El Niño–Southern Oscillation, El Niño event and could experience similar declines in the future. Conservation needs include regular monitoring throughout the range to determine population trends, particularly after El Niño years, restricting human access to important breeding colonies, and assessing interactions with fisheries.
The spot-billed pelican has an estimated population between 13,000 and 18,000 and is considered to be near threatened in the IUCN Red List of Threatened Species. Numbers declined substantially during the 20th century, one crucial factor being the eradication of the important Sittaung River, Sittaung valley breeding colony in Burma through deforestation and the loss of feeding sites. The chief threats it faces are from habitat loss and human disturbance, but populations have mostly stabilised following increased protection in India and Cambodia.
The pink-backed pelican has a large population ranging over much of sub-Saharan Africa. In the absence of substantial threats or evidence of declines across its range, its conservation status is assessed as being of least concern. Regional threats include the drainage of wetlands and increasing disturbance in southern Africa. The species is susceptible to bioaccumulation of toxins and the destruction of nesting trees by logging.
The American white pelican has increased in numbers,[ with its population estimated at over 157,000 birds in 2005, becoming more numerous east of the continental divide, while declining in the west. However, whether its numbers have been affected by exposure to pesticides is unclear, as it has also lost habitat through wetland drainage and competition with recreational use of lakes and rivers.][
Great white pelicans range over a large area of Africa and southern Asia. The overall trend in numbers is uncertain, with a mix of regional populations that are increasing, declining, stable, or unknown, but no evidence has been found of rapid overall decline, and the status of the species is assessed as being of least concern. Threats include the drainage of wetlands, persecution and sport hunting, disturbance at the breeding colonies, and contamination by pesticides and heavy metals.
The Dalmatian pelican has a population estimated at between 10,000 and 20,000 following massive declines in the 19th and 20th centuries. The main ongoing threats include hunting, especially in eastern Asia, disturbance, coastal development, collision with overhead power lines, and the over-exploitation of fish stocks. It is listed as near threatened by the IUCN Red List of Threatened Species as the population trend is downwards, especially in Mongolia, where it is nearly extinct. However, several European colonies are increasing in size and the largest colony for the species, at the Small Prespa Lake in Greece, has reached about 1,400 breeding pairs following conservation measures.]
Widespread across Australia,[ the Australian pelican has a population generally estimated at between 300,000 and 500,000 individuals. Overall population numbers fluctuate widely and erratically depending on wetland conditions and breeding success across the continent. The species is assessed as being of least concern.

Culling and disturbance
Pelicans have been persecuted by humans for their perceived competition for fish, despite the fact that their diet overlaps little with fish caught by people.[ Starting in the 1880s, American white pelicans were clubbed and shot, their eggs and young were deliberately destroyed, and their feeding and nesting sites were degraded by water management schemes and wetland drainage.][ Even in the 21st century, an increase in the population of American white pelicans in southeastern Idaho in the US was seen to threaten the recreational cutthroat trout fishery there, leading to official attempts to reduce pelican numbers through systematic harassment and culling.
Great white pelicans on Dyer Island, in the Western Cape region of South Africa, were culled during the 19th century because their predation of the eggs and chicks of guano-producing seabirds was seen to threaten the livelihood of the guano collectors.][ More recently, such predation at South African seabird colonies has impacted on the conservation of threatened seabird populations, especially crowned cormorants, Cape cormorants, and bank cormorants. This has led to suggestions that pelican numbers should be controlled at vulnerable colonies.][

and deliberate, targeted persecution, pelicans are vulnerable to disturbance at their breeding colonies by birdwatchers, photographers, and other curious visitors. Human presence alone can cause the birds to accidentally displace or destroy their eggs, leave hatchlings exposed to predators and adverse weather, or even abandon their colonies completely.
Poisoning and pollution
DDT pollution in the environment was a major cause of decline of brown pelican populations in North America in the 1950s and 1960s. It entered the oceanic food web, contaminating and accumulating in several species, including one of the pelican's primary food fish – the northern anchovy. Its metabolite Dichlorodiphenyldichloroethylene, DDE is a reproductive wikt:toxicant, toxicant in pelicans and many other birds, causing eggshell thinning and weakening, and consequent breeding failure through the eggs being accidentally crushed by brooding birds. Since an effective ban on the use of DDT was implemented in the US in 1972, the eggshells of breeding brown pelicans there have thickened and their populations have largely recovered.
In the late 1960s, following the major decline in brown pelican numbers in Louisiana from DDT poisoning, 500 pelicans were imported from Florida to augment and re-establish the population; over 300 subsequently died in April and May 1975 from poisoning by the pesticide endrin. About 14,000 pelicans, including 7500 American white pelicans, perished from botulism after eating fish from the Salton Sea in 1990.[ In 1991, abnormal numbers of brown pelicans and Brandt's cormorants died at Santa Cruz, California, when their food fish (anchovies) were contaminated with neurotoxin, neurotoxic domoic acid, produced by the diatom ''Pseudo-nitzschia''.
As waterbirds that feed on fish, pelicans are highly susceptible to oil spills, both directly by being oiled and by the impact on their food resources. A 2007 report to the California Fish and Game Commission estimated that during the previous 20 years, some 500–1000 brown pelicans had been affected by oil spills in California.][ A 2011 report by the Center for Biological Diversity, a year after the April 2010 Deepwater Horizon oil spill, said that 932 brown pelicans had been collected after being affected by oiling and estimated that 10 times that number had been harmed as a result of the spill.
Where pelicans interact with fishers, through either sharing the same waters or scavenging for fishing refuse, they are especially vulnerable to being hooked and entangled in both active and discarded fishing lines. Fish hooks are swallowed or catch in the skin of the pouch or webbed feet, and strong monofilament fishing line can become wound around bill, wings, or legs, resulting in crippling, starvation, and often death. Local rescue organisations have been established in North America and Australia by volunteers to treat and rehabilitate injured pelicans and other wildlife.
]
Parasites and disease
As with other bird families, pelicans are susceptible to a variety of parasitism, parasites. Avian malaria is carried by the mosquito ''Culex pipens'', and high densities of these biting insects may force pelican colonies to be abandoned. Leeches may attach to the cloaca, vent or sometimes the inside of the pouch. A study of the parasites of the American white pelican found 75 different species, including cestoda, tapeworms, trematoda, flukes, fly, flies, fleas, ticks, and nematodes.
The brown pelican has a similarly extensive range of parasites. The nematodes ''Contracaecum multipapillatum'' and ''C. mexicanum'' and the trematode ''Ribeiroia ondatrae'' have caused illness and mortality in the Puerto Rico, Puerto Rican population, possibly endangering the pelican on this island.
Many pelican parasites are found in other bird groups, but several louse, lice are very host (biology), host-specific.[ Healthy pelicans can usually cope with their lice, but sick birds may carry hundreds of individuals, which hastens a sick bird's demise. The pouch louse ''Piagetiella peralis'' occurs in the pouch and so it cannot be removed by preening. While this is usually not a serious problem even when present in such numbers that it covers the whole interior of the pouch, sometimes inflammation and bleeding may occur from it and harm the host.]
In May 2012, hundreds of Peruvian pelicans were reported to have perished in Peru from a combination of starvation and roundworm infestation.
Religion, mythology, and popular culture
The pelican (''henet'' in Egyptian language, Egyptian) was associated in Ancient Egypt with death and the afterlife. It was depicted in art on the walls of tombs, and figured in funeral, funerary texts, as a protective symbol against snakes. ''Henet'' was also referred to in the Pyramid Texts as the "mother of the king" and thus seen as a goddess. References in nonroyal funerary papyrus, papyri show that the pelican was believed to possess the ability to prophesy safe passage in the underworld for someone who had died.
Consumption of pelican, as with other seabirds, is considered not kosher as an Unclean animal#Judaism, unclean animal, and thus forbidden in Jewish dietary law.
An origin myth from the Murri people of Queensland, cited by Andrew Lang, describes how the Australian pelican acquired its black and white plumage. The pelican, formerly a black bird, made a canoe during a flood to save drowning people. He fell in love with a woman he thus saved, but her friends and she tricked him and escaped. The pelican consequently prepared to go to war against them by daubing himself with white clay as war paint. However, before he had finished, another pelican, on seeing such a strange piebald creature, killed him with its beak, and all such pelicans have been black and white ever since.
The Moche culture, Moche people of ancient Peru worshipped nature. They placed emphasis on animals and often depicted pelicans in their art.
Alcatraz Island was given its name by the Spanish because of the large numbers of brown pelicans nesting present. The word ''alcatraz'' is itself derived from the Arabic ''al-caduos'', a term used for a water-carrying vessel and likened to the pouch of the pelican. The English name albatross is also derived by corruption of the Spanish word.
Christianity
The ''Physiologus'', a didactic Christian text from the 3rd or 4th century, claims that pelicans kill their young when they grow and strike their parents in the face, but then the mother laments them for three days, after which she strikes her side and brings them back to life with her blood. This the ''Physiologus'' explains as mirroring the pain inflicted on God by people's idolatry, and the Crucifixion of Jesus, self-sacrifice of Jesus on the cross Salvation in Christianity, redeeming the sinful (see the Five Holy Wounds, blood and water gushing from the wound in his side).[ This text was widely copied, translated, and sometimes closely paraphrased during the Middle Ages, for instance by 13th-century authors William the Clerk of Normandy, Guillaume le Clerc and Bartholomaeus Anglicus.][ Likewise, a folktale from India says that a pelican killed her young by rough treatment, but was then so contrite that she resurrected them with her own blood.][ In a newer, also medieval version of the European myth,][ the pelican was thought to be particularly attentive to her young, to the point of providing them with blood by wounding her own breast when no other food was available. As a result, the pelican came to symbolise the Passion (Christianity), Passion of Jesus and the Eucharist,] supplementing the image of the lamb of God, lamb and the flag. A reference to this mythical characteristic is contained for example in the hymn by Saint Thomas Aquinas, "Adoro te devote" or "Humbly We Adore Thee", where in the penultimate verse, he describes Christ as the loving divine pelican, one drop of whose blood can save the world.
Elizabeth I of England adopted the symbol, portraying herself as the "mother of the Church of England". The Pelican Portrait of her was painted around 1573, probably by Nicholas Hilliard. A pelican feeding her young is depicted in an oval panel at the bottom of the title page of the first (1611) edition of the Authorized King James Version, King James Bible.[ Such "a pelican in her piety" appears in the 1686 reredos by Grinling Gibbons in the church of St Mary Abchurch in the City of London. Earlier medieval examples of the motif appear in painted murals, for example that of ''circa'' 1350 in the parish church of Belchamp Walter, Essex.
The self-sacrificial aspect of the pelican was reinforced by the widely read medieval bestiary, bestiaries. The device of "a pelican in her piety" or "a pelican vulning (from Latin wiktionary:vulnero#Latin, ''vulnerō'', "I wound, I injure, I hurt") herself" was used in religious iconography and heraldry.][
]
Origin in nature
The legends of self-wounding and the provision of blood may have arisen because of the impression a pelican sometimes gives that it is stabbing itself with its bill. In reality, it often presses this onto its chest to fully empty the pouch. Another possible derivation is the tendency of the bird to rest with its bill on its breast; the Dalmatian pelican has a blood-red pouch in the early breeding season and this may have contributed to the myth.[
]
Heraldry
Pelicans have featured extensively in heraldry, generally using the Christian symbolism of the pelican as a caring and self-sacrificing parent. Heraldic images featuring a "pelican vulning" refers to a pelican injuring herself, while a "pelican in her piety" refers to a female pelican feeding her young with her own blood. The King of portugal, King of Portugal John II of Portugal, John II adopted the pelican as is own personal sygil while he was Infante, evoking the christian symbology to equate the sacrifice of his blood to feed the nation. The pelican as a symbol also became sinonimous with the increasing charity efforts of the Santa Casa da Misericórdia, Santas Casas da Misericórdia during his reign and the reconstruction of the Caldas da Rainha, Hospital das Caldas da Rainha and the Hospital Real de Todos-os-Santos, which were mainly patronaged by his wife Eleanor of Viseu, D. Leonor.
The image became linked to the medieval religious feast of Corpus Christi (feast), Corpus Christi. The universities of Oxford and Cambridge each have colleges named for the religious festival nearest the dates of their establishment,[ and both Corpus Christi College, Cambridge,] and Corpus Christi College, Oxford, feature pelicans on their coats of arms.
The medical faculties of Charles University in Prague also have a pelican as their emblem. The symbol of the Irish Blood Transfusion Service is a pelican, and for most of its existence the headquarters of the service was located at Pelican House in Dublin, Ireland. The heraldic pelican also ended up as a pub name and image, though sometimes with the image of the ship ''Golden Hind''. Sir Francis Drake's famous ship was initially called ''Pelican'', and adorned the British Halfpenny (British pre-decimal coin), halfpenny coin.
Modern usage
The great white pelican is the national bird of Romania. The brown pelican is the national bird of three Caribbean countries—Saint Kitts and Nevis, Barbados, and Sint Maarten—and features on their coat of arms, coats of arms. It is also the state bird of the US state of Louisiana, which is known colloquially as the Pelican State; the bird appears on the Flag of Louisiana, state flag and Seal of Louisiana, state seal.[ It adorns the seals of Louisiana State University, Tulane University, Louisiana Tech University, the University of Louisiana at Lafayette, Loyola University New Orleans, Southeastern Louisiana University, and Southern University, and is the mascot of the New Orleans Pelicans NBA team, the Lahti Pelicans ice hockey team, Tulane University, and the University of the West Indies. A white pelican logo is used by the Portuguese bank Montepio Geral,] and a pelican is depicted on the Obverse and reverse, reverse of the Albanian 1 Albanian lek, lek coin, issued in 1996. The name and image were used for Pelican Books, an imprint (trade name), imprint of nonfiction books published by Penguin Books.[ The seal of the Packer Collegiate Institute, a pelican feeding her young, has been in use since 1885.
The pelican is the subject of a popular Limerick (poetry), limerick originally composed by Dixon Lanier Merritt in 1910 with several variations by other authors. The original version ran:]
