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 ...
Darwin's finches on the Galapagos Islands are a model system for the study of adaptive radiation. [10] Today represented by approximately 15 species, Darwin's finches are Galapagos endemics famously adapted for a specialized feeding behavior (although one species, the Cocos finch ( Pinaroloxias inornata ), is not found in the Galapagos but on ...
The use of tools has allowed woodpecker finches to be able to obtain prey that they would otherwise be unable to reach with their short tongues. [7] It is thought that this behaviour came to evolve due to the harshness of the dry and unstable environmental conditions of the Galapagos Islands. [5]
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. [2]
The Cocos finch was first categorized to be closer to the warbler finch clade due to the similar morphology of cousin warbler finches. [8] [9] The Cocos finch shares many morphological similarities to other Darwin's finches despite having been separated from the Galapagos Islands. [10]
The Galapagos islands are famous for plant and animal life; they are also famous due to the studies conducted by Charles Darwin, which led to the development of his theory of evolution by natural selection. [6] The Galapagos Island has now changed as and has been an area of rapid urbanization. [7]
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.

Like all but one of the other Darwin's finches, the small ground finch is endemic to the Galápagos Islands. Abundant and widespread, it is found on every island in the archipelago except for the Genovesa, Wolf and Darwin islands. It is most common in arid coastal and transition areas, though it moves into the highlands following the breeding ...
