Subject: [NEBirds] California Gull on Branched Oak Lake
Late this evening a small female CALIFORNIA GULL joined the thousand or so RING-BILLED GULLS out in the middle of Branched Oak Lake, scoped (very distantly) from Liebers Point. She was a 3rd-cycle bird, not noticeably bigger than the Ring-bills (although she was near back of the flock and size is tough to judge at such distance). The upperparts were noticeably darker gray than the Ring-bills, looking maybe a little uneven gray (probably due to admixed immature feathers), and with a large black spot on at least one tertial. The head was smudgy brown, the bill pale pink with a black tip. 
Very bad video (including some wing-flapping showing extensively dark wingtips) here:
Gull numbers on the lake have skyrocketed since I was last there just a few days ago, with many BONAPARTE'S GULLS newly arrived, and most but not all FRANKLIN'S GULLS gone. A few AMERICAN HERRING GULLS were out there as well.
