Interesting Facts

 The Great Gray Owl was first described by Johann Reinhold Forster in 1772. They have also been called the Phantom of the north, Spectral Owl, Lapland Owl, Spruce Owl, Bearded Owl and Sooty Owl.

 When hot, they will pant and droop their wings, exposing an unfeathered area called an apterid.

 They have been known to drive off predators as large as black bears when defending their nest.

 A group of owls has many collective nouns, including a "bazaar", "glaring", "parliament", "stooping", and "wisdom" of owls.
