There's a colony of pigeons that likes to hang out on the wires across the street to the south of my house. I took this photo of them from my dining room window in October.
Unlike then, today is sunny with a beautiful blue sky. I was on the front porch when suddenly a pigeon came hurtling over the front of it, swooped across the street to the schoolyard and slammed into the chain-link fence, recovered and flapped off again at high speed.
"What the ... ?!?" I just had time to think, before a peregrine falcon came hurtling after it in hot pursuit. The falcon turned neatly before it got to the fence, and they disappeared over some houses, the falcon only a few feet behind the pigeon.
Sorry pigeon, it looks like this will be your fate. (Don't click if you're squeamish.)
