Spot-winged pigeon

The spot-winged pigeon (Patagioenas maculosa) is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay.

The two subspecies of spot-winged pigeon differ significantly in their plumage. The nominate P. m. maculosa is 32 to 33 cm (13 to 13 in) long and weighs 308 to 347 g (10.9 to 12.2 oz). The adult male's forehead, crown, nape, hindneck, and breast are mostly dull purplish pink and the rest of the head and underparts are gray. The upper back and wing coverts are dark brown and show creamy white spots. The wings are mostly black above and pale gray below. The lower back and rump are bluish gray and the tail dark gray. The adult female is similar but the head and neck are generally duller. The juvenile is also similar, but duller all over with drab gray head and breast.

P. m. albipennis is slightly larger, 33 to 34 cm (13 to 13 in) long. The adults' head, neck, rump, and the whole of the underparts are blue-gray with a purplish wash that is especially pronounced in the male. The upper back and wing coverts are gray-brown. The folded wing shows a conspicuous white band that contrasts with the otherwise dark wing. As in the nominate subspecies, the juvenile is a duller version of the adult.
