The boreal owl or Tengmalm's owl is a small owl in the "true owl" family Strigidae. It is known as the boreal owl in North America and as Tengmalm's owl in Europe after Swedish naturalist Peter Gustaf Tengmalm or, more rarely, Richardson's owl after Sir John Richardson. Boreal Owls occur in stands of spruce, aspen, poplar, birch, and fir in the vast boreal forest that stretches across much of northern North America and Eurasia. Feeds mostly on voles and mice, also small squirrels, shrews, pocket gophers. Also eats small birds of various kinds, and insects, especially crickets.
