Tapaculo de pecho blanco

Identificación

The white-breasted tapaculo is 11 cm (4.3 in) long. Males weigh 13 to 18 g (0.46 to 0.63 oz) and females 12.2 to 16 g (0.43 to 0.56 oz). The male's upper parts are blue-gray and its rump reddish brown. The throat, chest, and belly are white and the flanks and vent area are chestnut with dark barring. Males in a small part of its range have more extensive dark underparts. Females and immatures are similar to the males but have browner upper parts.

Taxonomía

The white-breasted tapaculo and the Bahia tapaculo (Eleoscytalopus psychopompus) were formerly placed in the genus Scytalopus, but these two species are now known to be more closely related to the bristlefronts (genus Merulaxis). The Bahia tapaculo has also been proposed as a race of the white-breasted tapaculo, but genetic data refute that. The genetic data also show large differences between the northern and southern populations of white-breasted tapaculo.
