About

The boreal owl or Tengmalm's owl is a small owl in the "true owl" family Strigidae. It is known as the boreal owl or, more rarely, Richardson's owl after Sir John Richardson, in North America, and as Tengmalm's owl in Europe and Asia, after the Swedish naturalist Peter Gustaf Tengmalm.

Fun Fact

Boreal owls have asymmetrical skull openings — one ear is higher than the other — allowing them to pinpoint prey by sound alone in total darkness beneath the snow.
