The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book Darwin's Finches. [7] [8] Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy of Sciences, to whom Lack dedicated his 1947 book.

The genus Camarhynchus was introduced in 1837 by English ornithologist John Gould, with the large tree finch as the type species. [2] The name combines the Ancient Greek kamara meaning "arch" or "vault" with rhunkhos meaning "bill". [3] The members of the genus form part of a group collectively known as Darwin's finches. [4]
One of the first recorded examples of divergent evolution is the case of Darwin's Finches. During Darwin's travels to the Galápagos Islands, he discovered several different species of finch, living on the different islands. Darwin observed that the finches had different beaks specialized for that species of finches' diet. [11]
The small ground finch is one of Darwin's finches, a group of closely related birds which evolved on the Galápagos Islands. The group is related to the Tiaris grassquits, which are found in South America and the Caribbean. [2] When Charles Darwin first collected the species in 1835, he thought it was a finch.
These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family .

Charles Darwin, author of On the Origin of Species, was a great fan of the sundew, a cousin of the venus flytrap, and is once said to have remarked: "At this present moment, I care more about ...
The Cocos finch is a member of a group collectively known as Darwin's finches. [5] Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, [6] molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae. [7]
The large ground finch (Geospiza magnirostris) is a species of bird in the genus Geospiza. One of Darwin's finches, it is now placed in the tanager family Thraupidae and was formerly in the Emberizidae. It is the largest species of Darwin's finch.
