Screech-Owls are probably the most common owls in the United States. They are small, gray or reddish colored owls, with heavy streaking, small ear tufts, and glaring yellow eyes. They occur in a variety of habitats throughout the US and southern and western Canada, including forests, swamps, orchards, parks, and suburban woodlots. In the southwest, they also occur in desert areas. The Western Screech-Owl (Otus kennicottii) and the Eastern Screech-Owl (Otus asio) were once considered to be the same species. They are identical in plumage and overall appearance, and are best separated by range and vocalization differences. The songs and vocalizations of the two Screech-Owls are very different. The Eastern Screech-Owl gives either a quavering, descending series of whistled notes (which sounds a little like the "whinnying" of a horse), or a long, hollow-sounding trill. The Western Screech-Owl gives either a series of hollow, whistled notes which accelerate like the rhythm of a bouncing ball, or a short trill followed immediately by a longer trill.THUMTEXT Photo taken with a Nikkor 180mm EDAF f2.8 lens on Kodachrome 200 film.
