Formerly included M. venezuelensis and M. panamensis (which see). Geographical variation in present species complicated and poorly understood; further study needed. Plumage differentiation among races slight, and vast zones of intergradation currently recognized; populations in hybrid zone between nominate and brunnescens thought by some earlier authors to be migrant australis, but this is refuted by their having different breeding and moult schedules (many intermediate birds, however, distinguishable from australis only through these differences in timing). Three subspecies currently recognized.

Subspecies and Distribution
  • M. f. brunnescens J. T. Zimmer & Phelps, Sr, 1946 – core range a narrow belt of llanos in SW Venezuela (Táchira and Portuguesa E to NW Bolívar) and extreme NE Colombia (Arauca).
  • M. f. ferox (J. F. Gmelin, 1789) – Amazon Basin (from E slopes of Andes in S Colombia, Ecuador, Peru and N Bolivia) E to E & S Venezuela, the Guianas and Brazil.
  • M. f. australis Hellmayr, 1927 – lowlands from SE Bolivia, C Brazil (through S Mato Grosso, S Goiás, S Minas Gerais) and S through drainages of R Paraguay, R Paraná and R Uruguay to Argentina (S to S Corrientes) and extreme SW Rio Grande do Sul (Brazil); possibly also N & W Uruguay.
