Белоусая сойка Cyanocorax mystacalis

One of the most striking and recognizable birds of the dry “Tumbesian Region” that encompasses parts of western Ecuador and northwestern Peru. No other bird in range has a similar blue, white, and black pattern. Adults have yellow eyes. Young birds have dark eyes and slightly duller plumage. Noisy gangs of these impressive birds roam through dry forest giving a wide variety of calls, many of which have an odd, metallic quality.
