Observations

  1. Black-headed x Ring-billed Gull (hybrid)

    Number observed: 1

    Details: A big thanks to the two birders from Maine who alerted me to the fact that this bird was in with the RBGU flock in the east lot. I had parked in the "20 minute" lot and may not have checked those birds otherwise. Obvious white "wedge" on upperwing a la BHGU. Wingtip pattern similar to other examples of this combo. Some cloudy gray in the appropriate spots on the underwing. Some sternine influence evident in structure. Thin, short bill.
