The large ground finches have diverse food options. They eat mainly large seeds, and also pick Opuntia cactus fruits, caterpillars and large insects. They usually feed on seeds of Tribulus cistoides and, less commonly, on seeds of Bursera graveolens. They search for food most of the time on the ground. The adults feed their chicks mainly with ...

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]
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.
