The small Mauritian flying fox or dark flying fox (Pteropus subniger), known as a rougette to early French travelers, is an extinct species of megabat. It lived on the islands of Réunion and Mauritius in the Mascarene Islands of the Indian Ocean .
Palaeognathae contains five extant orders consisting of four flightless lineages (plus two that are extinct), termed ratites, and one flying lineage, the Neotropic tinamous. [ 2 ] [ 3 ] There are 47 species of tinamous, five of kiwis ( Apteryx ), three of cassowaries ( Casuarius ), one of emus ( Dromaius ) (another became extinct in historic ...
Several other native species exist in precariously small numbers, and their future on Guam is perilous. Most native forest species, including the Guam rail, were virtually extinct when they were listed as threatened or endangered by the U.S. Fish and Wildlife Service in 1984. Appreciable losses of the Guam rail was not evident until the mid-1960s.
Eight of the extinct bird species were found in Hawaii, including the Po`ouli, which was last seen in 2004. The Po`ouli is the most recently seen species of all 21 animals on the list.
The dodo was variously declared a small ostrich, a rail, an albatross, or a vulture, by early scientists. [3] In 1842, Danish zoologist Johannes Theodor Reinhardt proposed that dodos were ground pigeons, based on studies of a dodo skull he had discovered in the collection of the Natural History Museum of Denmark.
Gulls are typically gray or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with gray or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water.
Descriptions of the thylacine come from preserved specimens, fossil records, skins and skeletal remains, and black and white photographs and film of the animal both in captivity and from the field. The thylacine resembled a large, short-haired dog with a stiff tail which smoothly extended from the body in a way similar to that of a kangaroo. [31]
The rapid decline of the passenger pigeon has influenced later assessment methods of the extinction risk of endangered animal populations. The International Union for Conservation of Nature (IUCN) has used the passenger pigeon as an example in cases where a species was declared "at risk" for extinction even though population numbers are high.
