Gray Warbler-Finch Certhidea fusca

Small, slender-billed Galápagos finch. Best identified by its thin bill, brownish-gray plumage, and the island on which it is seen. Male sometimes has a faint, buffy wash on throat and face. Occurs only on Floreana, Española, Santa Fé, San Cristóbal, Genovesa, Marchena, Pinta, Wolf, and Darwin. Not found together with the very similar Green Warbler-Finch. Might be mistaken for a young female Yellow Warbler (some of which show only a trace of yellow), but note more finch-like bill and a shorter tail. Inhabits dry, coastal scrub and is often seen at the edge of beaches.
