Nest Materials
Great Gray Owls don’t build nests. Instead they use old raptor or Common Raven nests, or even nests built by western gray squirrels, and do not add any additional material to the nest. They also place their eggs in the broken tops of dead trees, human-made platforms, or in clumps of mistletoe.
