A wedge-billed Galápagos finch found only on Genovesa Island. Formerly considered a subspecies of Sharp-beaked Ground-Finch, and likewise has a sharp, thin bill with nearly straight edges. Bill is black on breeding male and dull orange on female and nonbreeding male. The only other slender-billed finch on Genovesa is the very different Gray Warbler-Finch, which has a thinner bill, tan (not sooty-black) adult male plumage, and paler and less heavily streaked female plumage. Common and easy to see in arid scrub near the coast.
