Bonaparte's Gull

Every time I think I've seen or photographed everything, something new and interesting pops up. This morning it was this lovely little gull, Bonaparte's Gull (Chroicocephalus philadelphia). It was swimming near another gull. I suddenly realized that it was much smaller than the other gull and I took another look through the telephoto lens. That distinctive spot behind its eye told me I was looking at something I had not seen before. Then, as though it was aware of my intense scrutiny, it spread its wings and took flight. According to Wikipedia, this gull was named after Prince Charles Lucien Bonaparte, a zoologist and nephew of Napoleon.
