The Flammulated Owl (Otus flammeolus) is a small, nocturnal owl approximately 15 cm (6 in) long with a 36 cm (14 in) wingspan. It breeds from southern British Columbia and the western United States to central Mexico. The Flammulated Owl is similar in appearance to the Western Screech-Owl but is only about one-quarter the mass, lacks large ear tufts (but has small ear tufts that are barely visible), has dark eyes and a different voice. The Elf Owl is smaller and the Northern Pygmy-Owl is approximately the same size.
