Endemic to the north coastal mountains of Venezuela, the attractive and boldly-patterned Scallop-breasted Antpitta is infrequently seen and is not well studied. It is a range-restricted species confined to the northern Venezuelan mountains, and is considered Near Threatened. It inhabits the understory of humid montane forest, usually above 1400 m, but occurring locally down to 800 m. There is some geographical overlap with Rusty-breasted Antpitta (Grallaricula ferrugineipectus) and with Slate-crowned Antpitta (Grallaricula nana), but these species generally occur at lower and higher elevations, respectively, than Scallop-breasted. Adult males have a largely orange rufous head, becoming paler over the face and throat; brown upperparts; above, and very pale yellow underparts, with a black malar stripe, and heavy black scalloping over the breast and flanks. The reproductive biology of Scallop-breasted Antpitta remains poorly studied, as indeed are most aspects of its behavior and ecology.
