Air superiority

Someone made this picture with I Can Has Cheezburger's LOLbuilder:
see more crazy cat pics

but my first thought is WTF How the toot is a red-winged blackbird riding on a red-tailed hawk IN THE AIR????

Turns out the photo is originally from this guy (I had to Google it since the captioner didn't attribute the photo). He says the blackbirds were attacking the hawk and it's happened more than once around his house. Please click through to his page, there are a couple more cool photos.

It's quite credible - they're pretty territorial little buggers when they're nesting. Seeing small birds mob a bigger one is always exciting. I saw a bunch of crows hassling an owl in broad daylight near the UW hospital once.
