Dettagli dell'osservazione

Possible 1st winter LBBG. Spotted by Austin O’Reilly flying upstream to the west of the point. We both noted the larger size than nearby RBGU. Overall dark gull with dark underwings. Pale belly (some photos show sharp black / pale demarcation line, but it appears to be shadow). Large dark bill with pale base. One photo possibly shows dark upper coverts on top of wing. Poor grainy photos attached. See Austin’s list for additional photos. https://ebird.org/checklist/S285624319
