Persistent strong north winds have kept this hatch-year male Northern Hawk Owl grounded for now. Males are normally the last to leave with juvenile and females leaving first.

Occasionally it is heard singing. The song of the male is a rolling whistled "ulululululul," lasting sometimes over 10 seconds. The female has a similar but shorter and hoarser song. It is possible the owl is calling to attract a mate.

The feathers around the throat can be seen fluttering as the owl vocalizes.
