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.
