Gull Identification: Iceland Gull
I took a photo of this gull last Thursday (Nov. 13), mainly because I hadn't seen much of anything else and I think it was all by itself in a field, an easy photo to capture. It was only this morning that I have really looked at it seriously and now realize I don't know what it is? I am used to seeing Herring Gulls and Ring-billed and Great Black-backed ones. This one is different from those I have mentioned. It does not have black tail feathers and its eye appears black. Its colour is more uniform overall without a strong contrast in patterning. And the black on its bill appears to be graduated.
Any help or suggestions as to its identification would be appreciated. Iceland Gull? Glacous Gull?
