The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers.
The rosefinches are a genus, Carpodacus, of passerine birds in the finch family Fringillidae. Most are called "rosefinches" and as the word implies, have various shades of red in their plumage. The common rosefinch is frequently called the "rosefinch". The genus name is from the Ancient Greek terms karpos, "fruit", and dakno, "to bite".
The Cocos finch or Cocos Island finch is the only one of the Darwin's finches not native to the Galápagos Islands, and the only member of the genus Pinaroloxias. Sometimes classified in the family Emberizidae, more recent studies have shown it to belongs in the tanager family, Thraupidae. It is endemic to Cocos Island, a Pacific island which is approximately 360 miles (580 km) south of Costa Rica.
The long-tailed paradise whydah or eastern paradise whydah is from the family Viduidae of the order Passeriformes. They are small passerines with short, stubby bills found across Sub-Saharan Africa. They are mostly granivorous and feed on seeds that have ripen and fall on the ground. The ability to distinguish between males and females is quite difficult unless it is breeding season. During this time, the males molt into breeding plumage where they have one distinctive feature which is their long tail. It can grow up to three times longer than its own body or even more. Usually, the whydahs look like ordinary sparrows with short tails during the non-breeding season. In addition, hybridization can occur with these paradise whydahs. Males are able to mimic songs where females can use that to discover their mate. However, there are some cases where females don't use songs to choose their mate but they use either male characteristics like plumages or they can have a shortage of options with song mimicry. Paradise whydahs are brood parasites. They won't destroy the eggs that are originally there but will lay their own eggs in other songbirds nest. Overall, these whydahs are considered least concerned based on the IUCN Red List of threatened species.
Pallas's rosefinch is a species of bird in the finch family Fringillidae. It is found in China, Japan, Kazakhstan, Korea, Mongolia, and Russia. Birds are occasionally reported from further west and there are records from several European regions, including Britain, but the cage-bird trade makes the origin of some such birds hard to assess. Its natural habitats are boreal forests and boreal shrubland.
