Possible Glaucous Gull at Fenton Pond
I birded Fenton Pond Saturday morning, March 7, 2020. At about 10:05 AM, a large white gull and 5 adult Western Gulls landed on the pond for a few minutes before taking off. The large white gull looked good for 1st Winter Glaucous Gull: larger than the nearby Westerns, white plumage including white wingtips, pink legs and large bill; however, my impression of the bill was 2-toned but mostly black, not pink with a well-defined black tip. Because of that, I hesitate to identify it as Glaucous Gull, considering the possibility of a hybrid or a very pale Glaucous-winged Gull. No photographs.
Fenton Pond is located in Otay Valley Regional Park in the southwest Chula Vista area and can be accessed from Beyer Blvd.
