Darwin's finches (also known as the Galápagos finches) are a group of about 18 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.
26 de jun. de 2019 · Learn how Darwin's finches, a group of 14 different species of birds with various beak shapes, helped Darwin develop his theory of natural selection. Discover how these birds adapted to different niches on the Galapagos Islands and how they influenced Darwin's writings on evolution.
Galapagos finch, distinctive group of birds whose radiation into several ecological niches in the competition-free isolation of the Galapagos Islands and on Cocos Island gave the English naturalist Charles Darwin evidence for his thesis that “species are not immutable.”
Learn about the 17 endemic species of Darwin's finches, small land birds that evolved from a common ancestor in Galapagos. Find out how they are threatened by invasive species and how conservation actions are protecting them.
