Observations

  1. Number observed: 1

    Details: From a distance of about 0.5 miles west of Montrose Harbor, I saw a large, dark bird with broad wings flying south approximately over Montrose Beach. I noted a couple of sets of rapid flapping of wings followed by a glide that made me think of an accipiter’s flight style. The bird appeared to be entirely black and evenly colored black (no paler areas), with broad wings and “fingered” primary tips. The tail was very short with sharp corners. The head protruded noticeably in front of the wings. I was not able to see the expected white patches at the base of the primaries, or anywhere else on the wing. The snappy, flap-flap-flap-flap wing beating followed by a gliding period continued as the bird moved south.
