    Cooper's Hawk Identification

    The Four Keys to ID

    • Size & Shape

      A medium-sized hawk with the classic accipiter shape: broad, rounded wings and a very long tail. In Cooper’s Hawks, the head often appears large, the shoulders broad, and the tail rounded.

      Relative Size

      Larger than a Sharp-shinned Hawk and about crow-sized, but males can be much smaller.
