Arremon brunneinucha

Buarremon brunneinucha
Includes Plain-breasted Brush-Finch


Subspecies differ mainly in the extent of grey on underparts of the body (less in South America2). The black band below the white throat is absent or at least reduced in some South American subspecies2, and in apertus ("Plain-breasted Brush-Finch") from Sierra de Los Tuxtlas, Mexico3.

This is likely subspecies suttoni
