Vampire Finch (Paperback)

High Quality Content by WIKIPEDIA articles! The Vampire Finch (Geospiza difficilis septentrionalis) is a small bird native to the Galapagos Islands. It is a very distinct subspecies of the Sharp-beaked Ground Finch (Geospiza difficilis) endemic to Wolf and Darwin Islands (Grant et al. 2000). The vampire finch is sexually dimorphic as typical for its genus, with the males being primarily black and the females grey with brown streaks. It has the largest and most pointed beak of all G. difficilis subspecies, and overall looks like a miniature Common Cactus-Finch rather than, as the other subspecies do, a large Small Ground-Finch with a straight bill (Schluter & Grant 1984). It has a lilting song on Wolf, a buzzing song on Darwin, and whistling calls on both islands; only on Wolf, a drawn-out, buzzing call is also uttered.(Grant et al. 2000)
