The black-winged ground dove is a species of bird in the family Columbidae. It lives in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru and is usually found in grassy areas near tree lines but roosts in Polylepis forest and Puya colonies. Throughout most of its range, it occurs at altitudes between but between in Chile. It moves to lower elevations in winter.
Taxonomy and systematics
The black-winged ground dove has two subspecies, the nominate M. m. melanoptera and M. m. saturatior.Description
The black-winged ground dove is long. Males weigh and females. The nominate adult male is grayish brown or earth brown above with a faint pink tinge. The throat is whitish and the underparts fawn pink with gray flanks. The closed wing shows a white edge and some pale gray. The eye color is highly variable as is the bare skin that surrounds it. The adult female's upperparts are a duller brown than the male's and the underparts less pink. Juveniles do not have the adults' pink tinge, and many feathers have buff edges. M. m. saturatior differs from the nominate by being darker and grayer above and less pink below.Distribution and habitat
The nominate subspecies of black-winged ground dove is a year-round resident from central Peru and adjacent Bolivia south through most of Chile and western Argentina. It breeds but does not winter on Tierra del Fuego. M. m. saturatior is found in the Andes of southwestern Colombia south to Ecuador's Azuay Province.The black-winged ground dove inhabits páramo in Colombia and Ecuador and puna in Peru, Bolivia, Chile, and Argentina. It is typically found in grassy areas near treeline but roosts in Polylepis woodland and Puya stands. In much of its range it occurs between but from in Chile. It moves to the lower elevations in winter.
