    Great Gray Owl Identification

    The Four Keys to ID

    • Size & Shape

      Great Grays are one of our tallest owls, and have broad wings and a long tail. They are big headed owls with a large facial disk. They dwarf most other owls in size but not by weight; their bulk is mostly made of feathers. Females are larger than males.

      Relative Size

      Larger than a Great Horned Owl in size, but not in weight. Smaller than a Bald Eagle.
