The gull was still present at 2:30 pm. Flew around the reservoir several times and made a weak attempt to catch a Hooded Merganser.

There is a 1st year Great Blacked-backed Gull at Brighton Dam. The only open water is in Montgomery County and that is where the bird is. Also 3 Herring Gulls and about 30 Ring-billed Gulls.
