White-bearded Antshrike

The white-bearded antshrike is 17 to 18 cm (6.7 to 7.1 in) long. This species exhibits some sexual dimorphism, and both sexes have a crest. Adult males have a black forehead, crown, and upper nape. The black of the crown extends down to the lores and eyes except for a faint white line through the eye. Their chin and the rest of their face are white that becomes pale buff around the lower nape. Their upperparts are reddish yellow-brown and their wings and tail are rufous. Their lower throat and breast are black and the rest of their underparts clay-colored. Voice: The white-bearded antshrike's song is a "slow series of 6-8 mournful, yet melodious notes, first rising, then lowering in pitch at the end". In the Argentina study, only two males were seen singing spontaneously and many males but few females sang in response to recordings. The species' call is "a complaining downslurred note" that is doubled or repeated in a longer series.
