The family Fringillidae are the "true" finches. The International Ornithological Committee (IOC) recognizes these 239 species in the family, distributed among three subfamilies and 50 genera. Confusingly, only 79 of the species include "finch" in their common names, and several other families include species called finches.
British finches are often associated with mules, a term used by cage bird breeders to refer to hybrids of finch species bred in captivity, such as that of a goldfinch and canary. There are now strict ringing regulations on British finches in places such as the UK , but they are still kept by aviculturists who care for them in much the same way ...
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]
The name Fringillidae for the finch family was introduced in 1819 by the English zoologist William Elford Leach in a guide to the contents of the British Museum. [3] [4] The taxonomy of the family, in particular the cardueline finches, has a long and complicated history.
Finches are a form taxon composed of unrelated but similar-looking songbirds within the family Fringillidae of the superfamily Passeroidea. The family Fringillidae includes numerous birds not called "finches" in their common names, including the crossbills , siskins , and waxbills .
The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face.
The woodpecker finch (Camarhynchus pallidus) is a monomorphic species of bird in the Darwin's finch group of the tanager family Thraupidae, endemic to the Galapagos Islands. [2] The diet of a woodpecker finch revolves mostly around invertebrates , but also encompasses a variety of seeds.
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.
