Black-chinned Robin Heteromyias brachyurus

A medium-sized bird of lowland and foothill forest interior. Black upperparts, head and narrow band across the chin, white underparts, prominent white eyebrow, and patch in the wing. Sits still in the understory, often perching on trucks or vertical branches. Very similar to Black-sided Robin and co-occurs in some areas, but Black-chinned lacks the black on the sides of the chest, has a broader white eyebrow and a black chin. Song, a simple series of breathless whistled notes, first descending then rising at the end.
