Mouse-colored Antshrike Thamnophilus murinus Scientific name definitions

Despite some degree of geographical overlap in upper Amazonia, west of the Rios Madeira and Negro, the Mouse-colored Antshrike is, more or less, the northern replacement of the vocally very similar Plain-winged Antshrike (Thamnophilus schistaceus). The present species, which is generally fairly common, occurs across the Guiana Shield, thence west to eastern Ecuador and Peru, and south to northernmost Bolivia, and is almost wholly restricted to lowland terra firme forest, whereas the Plain-winged Antshrike appears to favor seasonally flooded areas, at least in areas where the two species overlap. Mouse-colored Antshrikes also seem to join mixed-species flocks less frequently than Plain-winged Antshrikes; instead, pairs or lone individuals feed anywhere from close to the ground to the subcanopy, searching for insects, spiders, and other arthropods.
