Northern Saw-Whet Owl
The most nocturnal of our owls, and the smallest, as well. The upperparts are brown with white spots, and the underparts are white with heavy reddish streaks. The head appears large; the eyes are yellow, the bill dark; the forehead is brown with white streaks. There are no tufts on the head. Voice is a monotonous series: "too, too, too . . ." that is usually given on the breeding ground (and thus rarely heard in Missouri), or a rasping squeal like a saw blade being sharpened.
