The vampire ground finch (Geospiza septentrionalis) is a small bird native to the Galápagos Islands. Endemic to Wolf and Darwin Island, it was previously considered a very distinct subspecies of the sharp-beaked ground finch (Geospiza difficilis),[2][3] 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.[4]
