Geospiza conirostris (*)
Geospiza conirostris Ridgway, 1890
The Large Cactus Finch (Geospiza conirostris) is a species of bird in the tanager family Thraupidae. It is one of Darwin's finches, and is endemic to the Galápagos islands, Ecuador, where it is restricted to Española, Genovesa, Darwin, and Wolf Islands. This rather dark bird resembles the smaller and finer-beaked Common Cactus Finch, but the two species do not co-inhabit any island. There are significant differences between the subspecies of the Large Cactus Finch; G. c. conirostris of Española has a far larger beak than G. c. darwinii and G. c. propinqua of the remaining three islands.
Its natural habitat is dry shrubland and it is commonly seen on the ground. Its main food source is the cactus Opuntia.
