I've seen that shot of the burrowong owl! He's going all "Karate Kid" on the photographer. Cool!
The fellow with the white falcon (gyrfalcon) is a friend of mine, the reknowned author and buffalo rancher, Dan O'Brien. Shortly after that photo was taken the falcon passed away. Dan didn't take that too well.
This two part series is well worth the time to watch. It will give you an idea of the stark beauty of the Great Plains that I grew up in. Plus lotsa gratuitous shots of amazing big game. (The section on the Missouri Coteau is my favorite, that's the stuff I grew up in)
