One of several principally black, white, and yellow antwrens found in the canopy of Amazonian forests, the Sclater’s Antwren is reasonably widespread across southern Amazonia, where it ranges from eastern Peru and northern Bolivia east and north to south-central Pará, in eastern Brazil. The Sclater’s Antwren is usually considered to form a superspecies with the exclusively northern Amazonian Yellow-throated Antwren (Myrmotherula ambigua), and, like the latter species, the present species also is sometimes found in the same tall vine tangles worked by pairs of Pygmy Antwrens (Myrmotherula brachyura), in the many areas where these two overlap. There seems to be some vocal variation in the Sclater’s Antwrens across their range, especially east and west of the Rio Madeira, but apparently also between those populations on opposite banks of the Rio Xingu.
