Identification
Bill is very stout.
Male: Black throat and upper breast black, rest of body black with faint wavy white bars. Female rufous barred black, about equal with on upper and narrower black on lower parts; tail black and grey.
Geographic variation mostly in female plumage and voice. Female F. u. fulva has a more reddish, warmer color than the other subspecies and she is more heavily barred.
Distribution
Bolivia, Brazil, Colombia, Ecuador, and Peru; everywhere scarce and occurs in a patchy distribution.
Taxonomy
Closely related to Black-throated Antshrike.
Subspecies[1]
There are 4 subspecies:
- F. u. unduligera:
- North-western Amazonian Brazil on upper Rio Negro
- F. u. fulva:
- F. u. diversa:
- F. u. pallida:
- South-western Amazonian Brazil south of the Amazon; northern Bolivia (?)
There is a proposal to split Fulvous Antshrike (Frederickena fulva) as a monotypic species while leaving the other three subspecies together in this species.
Habitat
Moist lowland forests.
Behaviour
Unobtrusive: generally difficult to detect.
