Strix uralensis
Like a pale, giant Tawny Owl. Yellow bill, long, evenly barred, tail. Eyes dark. Facial disks pale, unmarked and almost fused, lacking the dividing wedge of Tawny Owl. In flight, note lack of pale base of primaries and much slower wing-beats than Tawny. Mild facial expression, but very aggressive at breeding ground.
Song: 6 -10 evenly spaced "ho"'s, starting silently and gradually rising in volume and pitch. Also an accented "ho-ho, ho-ho-it, ho-ho", three middle notes ascending and the two notes before and after descending. A variety of barking social sounds.
