520 _a"The adaptation that most excites bird-watchers is when these owls start showing up in unexpected places. Scientists call these mass movements to the south irruptions because--unlike long-eared and short-eared owls, which breed in some of the same regions--these owls don't migrate." (NATIONAL WILDLIFE) This article explains why some Arctic owls sometimes need to head south even though they don't migrate and also examines the importance of Canada's boreal forest to 290 species of birds.
