Blue-black Grosbeak Cyanoloxia cyanoides Scientific name definitions

Blue-black Grosbeak is resident over much of Middle America and northwestern South America, where it is widespread over forested lowlands, and is mainly found below 1000 m. There is virtually no geographical overlap with the extremely similar Ultramarine Grosbeak (Cyanoloxia brissonii). Female Blue-black Grosbeak is not blue at all, but is deep chocolate brown throughout. The male however is largely deep blue, becoming paler blue over the eyebrow, on the malars, and on the shoulder region. Over most of the its range, Blue-black Grosbeak is fairly common, but is occupies relatively dense forest understory, and is heard much more often than it is seen.
