Adult. Hundreds of photos obtained. No question of ID. Intermediate in size between Herring and Ring-billed Gulls. Yellowish legs, although not as bright yellow as nearby RBGU. Mantle a shade darker than surrounding HERG and RBGU. Dark eyes. Streaking on head, fairly extensive. Red and black spots on mandible. Bird was initially noted by yellowish legs as it was largely obstructed by other gulls. Closer inspection revealed dark eye, other features as above.
