The plumbeous pigeon (Patagioenas plumbea) is a species of bird in the family Columbidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Panama, Paraguay, Peru, Suriname, and Venezuela.
Taxonomy and systematics.
The plumbeous pigeon is most closely related to the ruddy pigeon ("P. subvinacea"), short-billed pigeon ("P. nigrirostris"), and dusky pigeon ("P. goodsoni"), and they have sometimes been placed in subgenus "Oenoenas". These six subspecies are recognized:
Vocal differences among and even within the subspecies hint that more than one species may be involved.
Description.
The plumbeous pigeon is long and weighs . Males have a dark gray head, neck, and underparts that sometimes have a pinkish or purplish tinge. The shoulders, back, rump, wings, and tail are dark grayish brown to drab olive. The hindneck sometimes has bronzy spots. The eye is red and surrounded by bare purplish red skin. The female's purplish wash is less intense and the neck spots more intense than the male's. Juveniles are duller than the adults, with very little purplish wash, and some feathers have rusty edges. The subspecies differ mostly in the amount and intensity of the pink or purple on the upperparts. Visually the plumbeous pigeon can be confused with the ruddy pigeon ("P. subvinacea") where their ranges overlap, but their vocalizations are very different.
