Finch
The finches have a near-global distribution, being found across the Americas, Eurasia and Africa, as well as some island groups such as the Hawaiian islands. They are absent from Australasia, Antarctica, the Southern Pacific and the islands of the Indian Ocean, although some European species have been widely introduced in Australia and New Zealand.
Darwin's finches
Darwin's finches (also known as the Galápagos finches) are a group of about fifteen species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is South-American "Tiaris obscurus." They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the "Beagle". Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands.
