holub temný Ducula cineracea

A large gray pigeon with yellow eyes and a dark bill. Shows uniform dark gray upperparts and paler gray head and underparts, becoming buff on the undertail. Juveniles display reddish-brown fringes to wing and tail feathers. Singles and pairs inhabit canopy of forest and woodland within foothills and mountains of Timor and Wetar. Distinguished from Metallic Pigeon by the entirely dark bill, the bright yellow eyes, the lack of red skin around the eye, and the lack of iridescent body markings. Gives a distinctive deep, stuttering, bubbling call, “brrrrrr,” sometimes preceded by a soft “whup” note.
