sea gulls

The gull at the top is a west coast sea gull. The gull at the bottom is an east coast sea gull. I don't really see any difference. The west coast sea gulls pretty much live only at the beach. We don't see them even a block or two inland. The east coast sea gulls move farther inland all the time. They can now be seen at suburban parking lots 60 miles from the Atlantic--this became fairly common about 20 years ago.
East coast sea gulls will walk right up to people and steal food. In densely populated areas, like Atlantic City, they have learned how to dive at people--to make them drop their food--and then eat their pizza.
