Formerly treated as a subspecies of Spotted Antpitta (Hylopezus macularius), Masked Antpitta is a poorly known, and apparently genuinely rare, bird that is endemic to northern Bolivia. BirdLife International considers the species to be Vulnerable, as it is known from only a few localities in southeastern Pando and northern Beni departments. It appears to favor low-stature, dense, second growth, including thickets. Given that all of the known sites for the species are subject to heavy human disturbance, Masked Antpitta might be far less threatened, and more geographically widespread, than currently thought. The plumage of this antpitta is characterized by the gray crown, dark mask, brownish olive upperparts, creamy white breast streaked with black, and warm buff undertail coverts. Very little has been formally published on the behavior and natural history of Masked Antpitta, but recent studies have provided the first detailed information, which suggest that its habits are similar to congeners.
