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 parasitic fly known as, Philomis downsi, was first documented in 1997; documentation of the parasite was found in the Galapagos Finches. [27] The adult flies lay eggs in the nest of birds, when those eggs hatch larvae will feed off of the blood of offspring. [27] The Philornis flies lay eggs in the nest including in the nestlings nostrils ...
Woodpecker finches mainly use moss, lichens, and grass as building materials for their nests. [5] During the 2 week incubation period when females are sitting on the eggs, males linger nearby, often feeding the females. [5] Female woodpecker finches typically lay around 2-3 eggs. [5]
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.
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.

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 ...
All species of Camarhynchus are endemic to the Galápagos Islands, and together with related genera, they are collectively known as Darwin's finches. [1] Formerly classified in the bunting and American sparrow family Emberizidae , more recent molecular genetic studies have shown it to belong in the tanager family.
