Timor Cuckoo-dove
The Timor cuckoo-dove (''Macropygia magna'') is a species of bird in the family Columbidae. It is found in Timor, Wetar and the eastern Lesser Sundas. It was previously lumped together with the Tanimbar cuckoo-dove and the Flores Sea cuckoo-dove as the dusky or bar-necked cuckoo-dove. It is rated as a species of least concern on the IUCN Red List of Endangered Species, International Union for Conservation of Nature Red List of Endangered Species. Status and conservation Since 1988, the Timor cuckoo-dove has been rated as a species of least concern on the IUCN Red List of Endangered Species. This is because although it has a restricted range, the range size is more than 20,000 km2 (7,700 mi2), and because it has a stable population trend. In addition, although its population numbers have not been determined, it is thought to be above 10,000, which is above the criterion to warrant a Vulnerable species, vulnerable ra ...

Alfred Russel Wallace
Alfred Russel Wallace (8 January 1823 – 7 November 1913) was a British naturalist, explorer, geographer, anthropologist, biologist and illustrator. He is best known for independently conceiving the theory of evolution through natural selection. His 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting, and quickly write an abstract of it, published in 1859 as ''On the Origin of Species''. Wallace did extensive fieldwork, first in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Birds Of Timor
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macropygia
''Macropygia'' is a genus of bird in the pigeon and dove family Columbidae. The genus is one of three genera known as cuckoo-doves. They are long tailed, range between 27 and 45 cm in length and have brown plumage. The genus ranges from India and China through Indonesia and the Philippines to Vanuatu and Australia. The genus ''Macropygia'' was introduced in 1837 by the English naturalist William John Swainson. The name combines the Ancient Greek ''makros'' meaning "long" or "deep" and "-pugios" meaning "-rumped"). The type species is the brown cuckoo-dove (''Macropygia phasianella''). The genus contains the following 15 species: * Barred cuckoo-dove (''Macropygia unchall'') * Amboyna cuckoo-dove (''Macropygia amboinensis'') * Sultan's cuckoo-dove (''Macropygia doreya'') * Ruddy cuckoo-dove (''Macropygia emiliana'') * Enggano cuckoo-dove (''Macropygia cinnamomea'') * Barusan cuckoo-dove (''Macropygia modiglianii'') * Timor cuckoo-dove (''Macropygia magna'') * Tanimbar cuckoo ...

Tanimbar Islands
The Tanimbar Islands, also called ''Timur Laut'', are a group of about 65 islands in the Maluku (province), Maluku Provinces of Indonesia, province of Indonesia. The largest and most central of the islands is Yamdena; others include Selaru to the southwest of Yamdena, Larat and Fordata (island), Fordata to the northeast, Maru and Molu to the north, and Seira, Wuliaru, Selu, Wotap and Makasar to the west. The Indonesian phrase ''timur laut'' means "east of the sea" or "northeast". The Tanimbar Islands are administered as the ''Tanimbar Islands Regency'' ( id, Kabupaten Kepulauan Tanimbar), a Regencies of Indonesia, regency of Maluku (province), Maluku. The Regency covers a land area of 10,102.92 km2, and it had a population of 105,341 at the 2010 census, rising to 123,572 at the 2020 census. The principal town and administrative centre lies at Saumlaki. Geography Geographically, the northeast islands are still part of the Lesser Sunda Islands. The Aru Islands Regency, Aru Isla ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

IUCN Red List of Endangered Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
