    Peregrine Falcon Identification

    The Four Keys to ID

    • Size & Shape

      Peregrine Falcons are the largest falcon over most of the continent, with long, pointed wings and a long tail. Be sure to look at shape as well as size—long primary feathers give the Peregrine a long-winged shape. As with most raptors, males are smaller than females, so Peregrines can overlap with large female Merlins or small male Gyrfalcons.
