Round my way, the seagulls tend to get into the picture like it or not. They're big, aggressive and utterly unintimidated by humans. We went out a few weeks ago to try to get a shot for the "growth" theme, and were just standing admiring the sea view at one point, when I turned round and this big bugger was about 4 feet away from me and staring at me hard.
I should add that I quickly pointed, pressed, and ran!
