I spent the weekend at Lake Michigan, and was surprised to see a seagull population there, even though it is freshwater, not the ocean. I can't recall ever seeing seagulls so far inland before. I've been to other very large freshwater lakes like Lake Tahoe (about 75 mile circumference), and there are no seagulls there...but of course the great lakes are much, much bigger than Tahoe. Thoughts?
