Plum Creek, Douglas County, Colorado.
Normally lumped with P. albilinea but separable at species level on account of black-tipped vs all yellow bill (2); paler grey underparts generally, shading to white on belly (3); wing-coverts paler grey with whitish fringes, resulting in a distinct wingband in flight, not as dark grey as mantle (2); gloss of nape and mantle bronze vs green (ns). There are also differences with P. albilinea in regard to song (scoring 5–6)#R. Race monilis previously lumped in nominate, but appears to be consistently larger and more richly coloured#R. Birds of Honduras and El Salvador previously separated as race letonai, but claimed differences are not consistent#R; those of N Nicaragua average slightly smaller and tend to be browner, but doubtfully separable as race parva#R. Three subspecies currently recognized.
