Of uncertain systematic placement, the genus Pygiptila, which is represented by just a single species, is widely distributed across much of the Amazon Basin, from southern Venezuela, in the north, south to northeast Bolivia, and from parts of the Guianas, in the east, west to eastern Ecuador. The heavy-billed Spot-winged Antshrike prefers the canopy and subcanopy of lowland evergreen forest, including both terra firme and seasonally flooded areas, and is most likely to be initially detected by its stuttering, yet quite musical, trilled loudsong. It is a reasonably common species, which regularly joins mixed-species flocks, wherein it can draw the observer’s attention by its habit of inspecting clusters of dead leaves. Seen well, both sexes should be readily identified: the male is largely gray with an obvious black cap and very neat white wing spots, while females are also gray above, with cinnamon wings, and a duller, clay-colored face and underparts.
