common cactus finch

  • Geospiza scandens

  • least concern

  • as their name suggests, they feed mostly on Opuntia cacti. When the Opuntia are in flower, the finches feed almost exclusively on pollen and nectar. during other times of the year, they will feed on Opuntia seeds and fruits. they will also feed on a range of other vegetative foods and invertebrates.

sharp beaked ground finch

  • Geospiza difficilis

  • least concern

  • although most populations feed mainly on seeds, those finches found on the small and remote islands of Wolf and Darwin often drink the blood of large seabirds, such as boobies.

  • this has given them an alternative name - vampire finch.
