Don't know what to think of this gull. This bird is much smaller than the surrounding HEGU's. Bill - small, by-colored, weak compared to HEGU. Pointed primaries indicated 1st yr. This would be a very faded 1st yr HEGU. I think there is some Kumlien/Thayers influence in there, somewhere. I believed I also photographed the same bird a couple of weeks prior to these. Looks like same gull to me, just a lot farther away. here- https://pbase.com/suzsull/image/140884852 just keep hitng next plenty of photos that show size difference.
