Ворона флореська Corvus florensis

An entirely black crow confined to the island of Flores. Found in small, vocal parties within forest in lowlands and hills. Overlaps with Large-billed Crow, and similarly large-billed, but Flores Crow is smaller-bodied with a relatively smaller bill, and lacks the pronounced steep forehead characteristic of Large-billed Crow. Flores Crow is also a forest species, avoiding open habitats, and has a distinctive voice. Vocalizations are odd for a crow, including babylike, whining, high-pitched “waa” and “we-we-we” calls, the latter sometimes followed by a deep “kyop.” Also gives high “kraaa” notes, a throaty, disyllabic “kwiyou,” and other gurgling sounds.
