Scops (Megascops) flammeola

DNA analyses indicated sister relationship between this species and New World Megascops (rather than with Old World Otus)#R#R; it lacks the trilled song typical of Megascops. Longer-winged population in N part of range sometimes separated subspecifically as idahoensis and darker birds from Guatemalan highlands described as rarus, but individual plumage variation appears to be continuous and biometric differences possibly clinal; other races proposed from S Mexico and Guatemala (meridionalis), Colorado (frontalis) and C British Columbia to NE California (borealis); exact type locality of species, however, apparently unknown, making objective use of subspecific names problematic. Treated as monotypic.

Distribution:

Breeds from SW Canada (SC British Columbia) S to NW & SW USA and NE, W & C Mexico (and E in highlands to S Puebla, and NE Oaxaca). Winters C & S Mexico to Guatemala and El Salvador#R.
