Yesterday I was checking out gulls near the Snake-Columbia River
junction. A ring-billed gull was present, but it did not have dark wing
tips; they were slate gray on top (with a hint of white edges) and white
on bottom. The rest of the bird seemed ring-billed gullish: bill size
and color, head shape and size, overall size, leg color, vocalization,
behavior. Anyone seen anything like this before? Is is a hybrid of some
sort? Maybe a lack of pigment?

Thanks for your insights!
