hiiripöllö Surnia ulula

Unique medium-sized owl of the boreal forest. Remarkably long-tailed for an owl; reminiscent of a small hawk in flight with quick, snappy wingbeats. Pale eyes give it an angry look. Brownish overall with white spotting above, barred underparts, and spotted crown. Feeds on small rodents by sight and sound. Often seen perched on the very top of a spruce tree or snag, surveying the surrounding landscape for prey. When rodent populations crash, large numbers of Northern Hawk Owls can move south of their normal range.
