Taxonomy

Taxonomy:

Pteroglossus Humboldti

Wagler

, 1827,

Brazil

.

Usually considered conspecific with P. inscriptus, but accorded species status here due to all-black (vs mostly yellow) lower mandible (3); base of bill and much of proximal upper mandible orange-tinged (vs yellow)#R (2); mouth-lining red (vs black)#R (2); rustier thighs (ns[1]); (in female) dull chestnut-chocolate of throat and head sides extends as indistinct but complete hindcollar, contra some statements#R suggesting that entire crown is dull chestnut-chocolate (ns[1]); significantly larger overall size (bill effect size 2.77, wing 3.92, score 2); narrow zone of intergradation or sporadic interbreeding in R. Madeira region (2). Species placed within P. viridis by some authors, but appears more appropriately treated as closest to P. inscriptus. Form from upper Amazonia, described as race didymus, now considered a synonym of humboldti; form from R Juruá described as olallae, and initially thought to be full species, found to be hybrid between humboldti and P. azara mariae. Monotypic.

Distribution:

S Colombia and W Brazil (E narrowly along Amazon to R Negro mouth in N, broadly E, S of Amazon, to R Madeira, crossing it occasionally in N and, more often, in S), S in lowlands E of Andes to NW Bolivia.
