Usually treated as conspecific with O. coronatus, O. mexicanus and O. occidentalis. Differs from coronatus in larger overall size (effect size for tail in males 4.03 [but n=4 swainsoni], score 2); plain smoky-rufous underparts vs densely olive-barred breast (3); and mid-chestnut vs very dark olive-brown head sides, neck sides, mantle and back (3). Differs from mexicanus in its somewhat smaller size with notably shorter bill (effect size in males –4.29 [but n=4 swainsoni], score 2); plain smoky-rufous underparts vs densely olive-spotted or olive-barred breast with palish rufous belly (3); dully rufous vs olive-brown head sides, neck sides, mantle and back (2); and white-tinged rusty vs strongly white chin and throat (ns[2]). Differs from occidentalis in characters outlined under that species. Also distinctive in call, which is significantly shorter (effect size 4.9; score 2) and higher-pitched (effect size also 4.9; score 2) than that of other taxa. Monotypic.

Distribution:

SE Brazil (S Bahia; S Minas Gerais and Rio de Janeiro S to E São Paulo, E Paraná and NE Santa Catarina#R).

Status and conservation

VULNERABLE. Confined to the dwindling and severely fragmented forests of SE Brazil (possibly also an old record from Goiás); a report from SE Paraguay is erroneous. Range... read more
