    Barn Owl Identification

    The Four Keys to ID

    • Size & Shape

      These medium-sized owls have long, rounded wings and short tails, which combine with a buoyant, loping flight to give them a distinctive flight style. The legs are long and the head is smoothly rounded, without ear tufts.

      Relative Size

      Larger than a screech-owl, but smaller than a Great Horned Owl.
