Parker's Antbird Cercomacroides parkeri Scientific name definitions

Described as recently as the late 1990s, Parker’s Antbird, named for the late Ted Parker, long was 'dismissed' as merely representing a highland population of the widespread Dusky Antbird (Cercomacra tyrannina). Parker's Antbird is confined to west central Colombia, where it occupies the borders and undergrowth of wet montane forest between 1100 and 1950 m; it occurs, on the west slope of the Western Andes, the northern and eastern slopes of the Central Andes, and also on the western slope of the Eastern Andes. The plumage of Parker's Antbird is extremely similar to that of Dusky Antbird, with males being differentiated solely in the slightly longer tail and marginally more olivaceous flanks, whereas females have the crown, head sides, upperparts, and wings olive gray, rather than brown, among other, smaller differences. Very little is known about the natural history of this species.
