Inverness, Scotland
I know I've told this story before, but probably not to everyone reading this. So, as you can see, the seagulls are pretty large in the UK. Well, what we have in Colorado are technically just "gulls" because they don't see the sea and maybe that is why they're smaller. Anyway...
One day at work, in London, I noticed this seagull rising in flight to our window, hovering for a bit, and then continually plunging down below (we were on the 3rd floor, or 2nd to the Brits). I distinctly remember thinking it looked very evil too, something about it's eyes... Well, my supervisor went out to lunch and when she returned she told us there was a dead pigeon outside the door on the sidewalk below. Apparently the seagull was preying on the pigeon. Eww. Click on that picture above and look at the eyes of the seagull. They all have this evil look to them (or at least, I think they do).
