Gyrfalcon Identification

The Four Keys to ID

  • Size & Shape

    Gyrfalcons are very large falcons. They have pointed wings, but they are not as pointed or as narrow as the wings of smaller falcons. The tail is relatively long. The body is thick and powerful, particularly in females, which are substantially larger than males.

    Relative Size

    Males are slightly larger than a Peregrine Falcon; females are about the size of a Red-tailed Hawk.
