Other common names: Flammulated Screech-owl

Taxonomy: Scops (Megascops) flammeola Kaup, 1853, Mexico.
Only New World species belonging to the Old World Otus assemblage referred to as subgenus Otus; differs from other New World Otus (subgenus Megascops) in lacking typical trilled song. Probably forms superspecies with O. brucei, O. senegalensis, O. scops and O. sunia. Longer-winged population in N part of range sometimes separated as idahoensis and darker birds from Guatemalan highlands described as rarus, but individual plumage variation appears to be continuous and biometric differences possibly clinal; also, other races d..

Taxonomy: Scops (Megascops) flammeola Kaup, 1853, Mexico.
Only New World species belonging to the Old World Otus assemblage referred to as subgenus Otus; differs from other New World Otus (subgenus Megascops) in lacking typical trilled song. Probably forms superspecies with O. brucei, O. senegalensis, O. scops and O. sunia. Longer-winged population in N part of range sometimes separated as idahoensis and darker birds from Guatemalan highlands described as rarus, but individual plumage variation appears to be continuous and biometric differences possibly clinal; also, other races described from S Mexico and Guatemala (meridionalis), Colorado (frontalis) and C British Columbia to NE California (borealis); 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 to C & S Mexico and Guatemala, possibly El Salvador.
