Northern Saw-whet Owl

Birders who prowl through conifer groves in winter sometimes find this round-headed little gnome perched there, sitting still as if to avoid notice. Avoiding notice is a task at which this owl often succeeds; it is overlooked in many places where it occurs. Late at night in the breeding season, males give a rhythmic tooting song that may go on for hours with scarcely a break. The bird was named for this song, which reminded settlers of the sound of a whetstone sharpening a saw.
