The Dougand’s Antwren is a little-known antbird in the genus Herpsilochmus restricted to the canopy of terra firme forest in extreme western Amazonia in northeastern Peru, eastern Ecuador, and southern Colombia. Most species within this genus, and Dougand’s Antwren in particular, are inherently difficult to see, and most sightings of this species have been made from a canopy tower or walkway. It is the only Hepsilochmus in Amazonia that has white, as opposed to yellow, underparts. Males are mostly gray above, grayish-white below, has a black cap, and has white tips to the wing coverts forming bold wingbars. As with other species in this genus, it has white superciliary, and white outer tail feathers, giving the bird a white underside of the tail. Females are buffier below, and have a brown, as opposed to black cap. Perhaps overlaps with the Ancient Antwren (Herpsilochmus gentryi), but that species is found in the canopy of varillal forest growing in white sands, and is yellow underneath. Song very similar to the Moustached Antwren (Myrmotherula ignota) or the Pygmy Antwren (Myrmotherula brachyura), and sounds like a bouncing ball “tu-tu-tu-tu-tutututututu” speeding up at the end, but Dougand’s is slightly lower pitched and slower (than Pygmy). All three can overlap in the forest canopy in northeastern Peru.
