<P> 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 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 . </P>
