Title: Black-backed Gull?
Post by: Dinusaur on June 27, 2015, 07:15:39 PM

Found this one today among a group of gulls in the new construction area of Cell 2 in Tommy Thompson Park. Is it a first year Lesser or Greater Black-backed Gull? Compare its size against the ring-billed gulls in the picture. It is definitely bigger that the rest. Thanks in advance.
