Big Bird (not yet formally named): In 1981, a hybrid male arrived at Daphne Major island. Its mating with local Galapagos finches (specifically G. fortis) has produced a new "big bird" population that can exploit previously unexploited food due to its larger size. They do not breed with the other species on the island, as the females do not ...
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.
Large ground finch (Geospiza magnirostris)The Daphne Major finches are a group of Darwin's finches that inhabit Daphne Major island of the Galápagos.The common cactus finch (Geospiza scandens) and the medium ground finch (G. fortis) are the main species; [1] while the large ground finch (G. magnirostris) and the Española cactus finch (G. conirostris) are regular immigrants.

The vampire ground finch (Geospiza septentrionalis) is a small bird native to the Galápagos Islands. Endemic to Wolf and Darwin Island, it was previously considered a very distinct subspecies of the sharp-beaked ground finch (Geospiza difficilis), [2] [3] but the International Ornithologists' Union has split the species based on strong genetic evidence that they are not closely related, and ...
The small ground finch is the smallest of the ground finches, measuring 11 cm (4.3 in) in length. [ 8 ] [ nb 1 ] Its beak is short and pointed, with a slightly curved culmen . [ 8 ] On average, its beak is smaller than that of the medium ground finch , but there is a significant overlap in size between the two, particularly on islands where ...
Medium ground finches have a better chance of survival in their habitat than small ground finches, due to their beak size. [18] The beak size of medium ground finch can evolve in a relatively short period of time, depending on if it is a wet season or dry season. [19] Survival and beak size of the birds are fueled by the environment.
The estrildid finches are small passerine birds of the Old World tropics and Australasia. They are gregarious and often colonial seed eaters with short thick but pointed bills. They are all similar in structure and habits, but have wide variation in plumage colors and patterns. One species has been recorded in Ecuador
Big Bird, also known as the Big Bird lineage, is one of the species of Darwin's finches that is exclusively present on Daphne Major of the Galápagos Islands.It originated from a mixed-breed of the Española cactus finch (Geospiza conirostris) and the medium ground finch (Geospiza fortis) that immigrated to Daphne Major in 1981.
