Bamboo antshrike
The bamboo antshrike is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, and Peru.
Taxonomy and systematics
Until the 1980s what is now the bamboo antshrike was treated as a subspecies of the fasciated antshrike. The two are the only species in genus Cymbilaimus. The bamboo antshrike is monotypic.Description
The bamboo antshrike is long and weighs. This species exhibits significant sexual dimorphism. Both sexes have a small crest, a dark brown iris, and a somewhat heavy bill with a hook at the end like true shrikes. Adult males have a black forehead and crown; the rest of their plumage is thin black and white bars. Females have a rufous crown with black tips on the crest feathers. Their upperparts and tail have thin dark brown and pale yellowish brown bars, their throat is plain buffy white, and the rest of their underparts are mostly plain cinnamon-buff with darker barring on the sides and flanks.Distribution and habitat
The bamboo antshrike is found in the western Amazon Basin of southeastern Peru, western Brazil, and northwestern Bolivia. In Peru it occurs in the departments of Ucayali, Cuzco, Madre de Dios, and Puno. In Brazil it occurs in Acre and Rondônia states, and in Bolivia the departments of Pando, La Paz, and Beni.The bamboo antshrike almost exclusively inhabits stands of bamboo, typically of genus Guadua, in humid lowland and foothill forest. There it favors the upper levels of the bamboo. It sometimes is found in dense tangles of vines in floodplain forest, where it is more broadly seen from the mid-storey to the canopy. In elevation it ranges up to about.
