Really amazing detail! I've never tried photographing these. When I run across them they always seem so jumpy, I'm impressed that you can be quick enough to catch them so sharply, or else to hypnotize them into staying in one place for longer.
Another awesome capture. There is a guy on Facebook that puts some amazing shots like this. I think his name is Justin Streeb. He puts all of the information down that he uses for each shot. You might want to take a look.
