Mangrov İspinozu Camarhynchus heliobates

A critically endangered Galápagos finch and one of the world’s rarest birds. Currently known only from mangroves at a few sites (with restricted access) on Isabela. Formerly found on Fernandina, but there are no recent substantiated records there. Both sexes typically have brown upperparts, whitish underparts with tan streaking, and a faint eyebrow. Some older males may have a faint, dark hood. Bill is relatively long, with a curved upper edge and mostly straight lower edge. Male’s bill is black when breeding and slightly paler at other times. Female’s bill is orange. Similar to Woodpecker Finch, but that species has a longer bill and less prominent streaking.
