I have three gulls today. All of these were found in the Salton Sea area in mid April on the same day. I remember the first (and last) time I saw the Yellow-footed Gull. It was back in 1988 in the same general area. It was 114F and 100% humidity. Miserable. This day was mid 70s. Very comfortable.
We do get Bonaparte’s Gulls on Cape Ann. But it’s a winter bird for us and we do not get to see breeding plumage adults.
A breeding plumage Franklin’s Gull, what a treat!
