Parker's Antbird

Parker's antbird is 13.5 to 15 cm (5.3 to 5.9 in) long. Males are almost entirely slate gray, with somewhat lighter underparts than upperparts. They have a hidden white patch between their scapulars and narrow white tips on their wing coverts and outer tail feathers. Their flanks have an olivaceous tinge. Females have an olive brown or olive brown tinged gray crown and ear coverts, a paler olive brown supercilium, and gray lores. Their upperparts, wings, and tail are olive brown. They have a very small or no interscapular patch. Their throat and underparts are tawny buff or cinnamon rufous. Both sexes have a rich chocolate brown iris, a brownish black maxilla, a horn-colored mandible with a brownish black tomium, and brownish black legs and feet.

Parker's antbird is found on the western slope of Colombia's Western Andes, the northern and eastern slopes of the Central Andes, and the western slope of the Eastern Andes. It inhabits the understorey and edges of humid subtropical montane forest, nearby secondary forest, and bamboo thickets in both forest types. In elevation it ranges between 1,100 and 1,950 m (3,600 and 6,400 ft).

The diet of Parker's antbird has not been detailed but is known to include a variety of insects; it appears to favor beetles. Single birds, pairs, and family groups usually forage low to the ground but do feed into the forest mid-storey. It typically hops through dense vegetation, taking prey from vegetation mostly by gleaning from a perch. It seldom joins mixed-species feeding flocks.
