Behavior
Surnia ulula rarely walks on the ground. A waddle-like motion characterizes its walk. Its flight is "rapid and strong." When moving from one perch to another, it quickly dives down, stays low, and then abruptly flies up to the new perch. The Northern Hawk Owl participates in self-maintaining behavior through preening and snow-bathing. These animals are primarily diurnal but may also be active at night. A male establishes its territory a few weeks before nesting and attracts a female to the nest site through an Advertising Call (Duncan and Duncan, 1998)
