I posted a clip from this video a while back, but here's the whole video, 7 minutes long, chock full of Golden Eagle mayhem.
Warning, some of this is pretty gruesome (and therefore awesome). The final scene is the best.
Saw this on a "Planet Earth" I was watching last night. Absolutely unbelievable, probably the coolest bird footage I've ever seen. The best part starts at 2:00.
