Sign in to see your badges



A small, widespread Galápagos finch. Bill is longer than it is deep, appears somewhat pointed, and has only a slight curve to the upper edge. Lower edge of bill is mostly straight. Bill size varies among individuals, and not all birds can be accurately identified. Bill is black on breeding male and dull orange on female and nonbreeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are streaked with gray. Medium Ground-Finch has thicker, less pointed bill. Sharp-beaked Ground-Finch has bill that is slightly more pointed and is less rounded on the upper edge. Found in a wide variety of habitats on most islands, but absent from Genovesa, Darwin, and Wolf.
