The large ground finch or Geospiza magnirostris is a species of bird. One of Darwin’s finches, it is now placed in the family Thraupidae and was formerly in the Emberizidae.
The large ground finch or Geospiza magnirostris is endemic to the Galapagos Islands, and is found in the arid zone of most of the archipelago, though it is absent from the southeastern islands (Floreana, Española, San Cristóbal and Santa Fé).
The large ground finch or Geospiza magnirostris is the largest species of Darwin’s finch both in total size and size of beak. It has a large, short beak for cracking nuts to get food.
The adult male large ground finch or Geospiza magnirostris is almost entirely black, except the slightly browner wings and tail, and the white streaked black vent. The tail is relatively short. The massive bill has thick base of lower mandible and curved culmen. Like in other male finches, the bill is black during the breeding season, turning orange-yellow outside this period. The eyes are dark brown. Legs and feet are blackish.
The Large Ground Finch or Geospiza magnirostris feeds mainly on large seeds, and also takes Opuntia cactus fruits, caterpillars and large insects. It feeds on seeds of Bursera graveolens, but its main food source includes the woody seeds of Tribulus cistoides. Its large, strong bill allows it to crack open these hard seeds.
The immature male is intermediate between male and female, with blacker head and breast, diffuse streaking on back and belly, and blackish wings.
The Large Ground Finch or Geospiza magnirostris voice differs from other finches due to bill structure and shape. Usually, the male sings only one song type, a nasal repetition of 2-3 notes “chzweee-chzwee” with lower-pitched sounds and slower speed than those of the Medium Ground-Finch. The call is a high-pitched “tzeeeeppp”.
