Crescent-faced Antpitta

"Grallaricula are very small Andean antpittas, found mostly in low dense vegetation (such as treefall gaps, stream edges, and bamboo thickets)." The crescent-faced antpitta is 11 to 12 cm (4.3 to 4.7 in) long and weighs 17 to 22 g (0.60 to 0.78 oz). The sexes have the same plumage. Adults have the eponymous white crescent from the crown through the lores and almost to the throat and a small white spot behind the eye. Their crown and nape are dark sooty gray and their face black. The crescent's bottom becomes ochraceous buff and they have a spot of that color on the side of their neck. Voice: What appears to be the crescent-faced antpitta's primary song is "an ascending series of piping notes, last several rather shrill, e.g., pu-pu-pu-pe-pe-pee-pee-pi-pi-pi?". Other vocalizations include "a soft, downslurred whistle" and a "Chup!". The species is seldom heard or seen unless prompted with a recording. When seen singing it is usually on a low perch in dense vegetation.
