Hitherto treated as conspecific with G. aequinoctialis and G. chiriquensis, but differs from latter in characters given under that species, and from former in its face-mask reduced to lores and subocular area, i.e. ear-coverts and area above eye olive-green vs black (3); two-part song consisting of some simple (usually upslurred notes) and rather abruptly shifting to a more warbled phrase vs short sweet warble (2); absence of a long call (in aequinoctialis a series of descending notes) (2). Race peruviana differs from nominate by its paler grey crown (1); larger size (allow 2); and distinct ending to song, a descending twittered series of (symmetric overslurred) notes (at least 2)#R; thus a strong contender for species rank and further research needed. Two subspecies recognized.
