Appearance

Distinguishing Characteristics

Antpittas (Grallaria) have a distinctive morphology: they are plump-bodied, with short tails and notably long tarsi. The White-throated Antpitta is a medium sized antpitta with a very simple plumage pattern: basically it is olive brown above with a bright rufous crown, and gray below, with a white throat.

Similar Species

In most areas where it occurs, the White-throated Antpitta is distinctive. In the northern portion of its range, however, in Cuczo, Peru, the Rhite-throated Antpitta overlaps with one similar species, the Red-and-white Antpitta (Grallaria erythroleuca). Even in this region, however, there is only very limited elevational overlap, as Red-and-white occurs from 2100-3000 m, whereas White-throated Antpitta is at 1150-2100 m. Both species have a reddish brown crown and a white throat, but the back and wings of the White-throated Antpitta are olive, not reddish brown as in Red-and-white, and the breast and belly of White-throated are pale gray, lacking the rufous flanks and breast band of Red-and-white.

Detailed Description

The following description is based on Krabbe and Schulenberg (2003):

Adult: Sexes similar. The crown and sides of the head are bright chestnut-rufous with prominent a white eyering and white lores. Otherrwise the upperparts are olive brown; tail dull brown, slightly reddish. The edges of the primaries are tawny brown. The throat is white, contrasting with the breast and belly, which are pale to medium gray, darkest on the sides of the breast and flanks. The flanks also are washed with olive. Undertail coverts pale gray, mixed with olive.

Juvenile: Undescribed?
