Unusual gull on Teal pond - unsure of id. Larger than nearby ring billed gull. Pink feet observed in flight and roosting. Long wings, dark tips with few white spots. Tail all white. Head white with grey flecks. Back uniform gray but lighter than nearby ring billed gulls. Dark eye. Bill spot dark and only on lower mandible, medium size, hooked. Head and bill seem small for Herring gull. Head shape also more rounded. Feautures seem split between Iceland Thayer's and small Herring.
