White-throated Antpitta Grallaria albigula Scientific name definitions

The White-throated Antpitta is an attractive species, with a chestnut-rufous head, gleaming white throat set off from the rest of the gray underparts, and a brown mantle, wings, and tail. It is among the least known of the montane Grallaria antpittas, and has the southernmost range within the genus. Described from Peru, it wasn’t found in Bolivia until a decade later and in Argentina not until almost half a century after its description. It is known, discontinuously, from southeastern Peru to Bolivia and northwestern Argentina. It forages almost exclusively on the ground for invertebrate prey, although few specifics have been published. Like its congeners, the White-throated Antpitta is most likely to be initially detected by voice, an easily imitated, double-noted call. It is a medium-sized antpitta with a very simple plumage pattern, and is unlikely to be confused with other species within its range. The White-throated Antpitta is very difficult to see, like most of its congeners, even where fairly common. Its elusive behavior, combined with its restricted range, have resulted in it being one of the most poorly studied Grallaria. Its diet is very poorly documented and its habitat requirements are unclear, possibly varying geographically. Even the validity of the only described subspecies demands investigation. Its nest and breeding biology remain unknown.
