Turdus ignobilis debilis

Rio Madeira, western Brazil


Very recently proposed for separation from T. ignobilis based on strong molecular and relatively weak plumage differences#R. This accepted here, given (vs all other taxa in T. ignobilis as constituted in HBW, including T. arthuri) greater amount of white on throat including small white mark on uppermost breast (2); more white on underparts (1); olive-brown upperparts (distinction too subtle to score; ns); use of floodplain (várzea) forest (1); and leisurely song (for speed allow 2) of single complex notes given one by one (allow 2)#R. Monotypic.

What do (1) and (2) mean? Learn more about the scoring system.

Amazon floodplain from S Colombia, E Ecuador and E Peru to N Bolivia and NW Brazil (between R Negro and R Madeira)#R.
