The Flammulated Owl is found in montane habitats from southern Mexico north to British Colombia. It is primarily found in open coniferous forest, especially Ponderosa Pine, though habitat preferences change farther south. The Flammulated Owl is a complex migrant. Throughout most of western North America it only occurs during the summer breeding season but is resident in the western and southern Cordilleras of Mexico, only wintering father south in Guatemala. The Flammulated Owl is a nocturnal species and feeds almost entirely on nocturnal insects, especially owlet moths. It is the only New World member its genus, Otus, a large old world radiation. The New World Screech-Owls (Megascops) are superficially similar, but differ in vocalizations and morphology.
