Flammulated Owl
Psiloscops flammeolus
The flammulated owl (Psiloscops flammeolus) is a small migratory North American owl in the family Strigidae. It is the only species placed in the genus Psiloscops.
The flammulated owl is a small, nocturnal owl approximately 15 cm long with a 36 cm wingspan. With such large wings for a small body, they can fly rapidly from tree to tree. Males and females can be distinguished by their weight. Females are larger, ranging from 62–65 g and males are smaller ranging from 50–52 g. The owl gets the name flammulated from the flame-like markings on its face.
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), and has dark eyes and a different voice. The elf owl is smaller and the mountain pygmy owl is about the same size. The call is a series of relatively deep, single or double hoots.
