Vampire ground finch

Common card · No. 203375

The Vampire ground finch (Geospiza septentrionalis) or Vampire finch is a small bird native to the Galápagos Islands. A member of the Darwin's finches group, it is known for its unique parasitic behavior of feeding on the blood of other birds. It is endemic to Wolf and Darwin Island. The species was previously considered a very distinct subspecies of the sharp-beaked ground finch (Geospiza difficilis), but the International Ornithologists' Union has split the species based on strong genetic evidence that they are not closely related, and divergences in morphology and song.
