Illustration of Great Gray Owl (Strix nebulosa)

The Great Gray Owl is the largest owl in North America by length, with an enormous facial disc that acts as a parabolic reflector to focus sound from prey moving beneath two feet of snow. Despite its imposing size, it is a relatively light bird — mostly feathers. It hunts by plunging through snow crusts to catch voles detected by sound alone.

Habitat
Dense boreal forests and subalpine meadows
Diet
Voles and other small mammals detected beneath snow
