Cercomacra nigrescens fuscicauda
J. T. Zimmer, 1931,
Lagarto, upper Río Ucayali, Peru.
Recently split from C. nigrescens on account of its strong vocal distinctiveness#R; differs in its (in female) paler, duller ochraceous overall colour (1); tawny-washed crown, producing a less contrasting facial pattern (1); greyer flanks (1); more clearly marked wing-coverts (ns); and (in male) song with much faster pace (from published data#R effect size vs next fastest 11.4, score 4) and many more notes (effect size vs next most numerous 3.7, score 2)#R. In addition, C. fuscicauda is confined to riparian habitats, although C. nigrescens, which occurs in other habitats, also uses riparian formations. Monotypic.
Lowlands in E Ecuador, E Peru, extreme SE Colombia (S Amazonas), SW Amazonian Brazil (SW Amazonas, Acre) and NE Bolivia (Pando, La Paz, W Beni, Cochabamba).
