Note large-bodied aspect, blocky head, large black bill, and "salt-and-pepper" mantle.
Detalles de la observación
I first saw it, briefly, along the north beach, where it stood out as larger and blockier than nearby Herring Gulls. The big bill, blocky head, and "salt-and-pepper" mantle stood out. The flock soon took off, with the Great Black-backed going out into the middle of the reservoir. See below, distant/grainy but diagnostic photos.
