Subspecies
Geographical variation over species' large range slight, despite number of named subspecies. There seems to be more variation within nominate than among many of proposed subspecies. Highly likely that many or most subspecies are not diagnosable. The majority were described from few specimens and few localities, and many of the characters used to define them seem invalid. Racial identity of birds from extreme eastern Peru and north-eastern Bolivia (Pando) and others from extreme eastern and south-east of latter country uncertain and the first are tentatively included with purusianus and the second with connectens. Listed distributions of several subspecies should be interpreted with caution.
The following 11 subspecies are recognised:
septentrionalis Zimmer, JT, 1929 - Costa Rica and western Panama (western Chiriquí).
incomptus Wetmore, 1970 - Extreme eastern Panama (Cerro Pirre).
phelpsi Meyer de Schauensee, 1959 - Santa Marta Mts, in northern Colombia.
perijanus Phelps & Phelps Jr, 1954 - Perijá Mts, and eastern Andes of western Venezuela (southern Táchira) and north-eastern Colombia (Santander).
heterurus Cabanis & Heine, 1860 - Northern Venezuela (east to Paria Peninsula), Trinidad, and eastern Andes from Colombia (southern from Cundinamarca) south to north-eastern Ecuador.
guayae Hellmayr, 1920 - Lowlands of western Ecuador (southern from Esmeraldas) and north-western Peru (Tumbes, Piura).
peruvianus Zimmer, JT, 1935 - Andean foothills in Ecuador and Peru (south to Puno).
purusianus Todd, 1925 - Extreme eastern Peru, central Brazil (R Purús east to R Tapajós) and north-eastern Bolivia (Pando).
connectens Chapman, 1919 - Foothills from Bolivia (southern from La Paz, also in extreme eastern and south-east) south to north-western Argentina (south to Tucumán).
chapadensis Zimmer, JT, 1935 - Eastern Bolivia (Beni) and south-western Brazil (Rondônia and Mato Grosso east to Maranhío, Piauí and Goiás).
rutilans Temminck, 1821 - South-eastern Brazil (southern from Bahia and Minas Gerais) south to north-central Paraguay and north-eastern Argentina (Misiones, north-eastern Corrientes).
