A contender for best displaying raptor in the world. The amazing roll overs, twists and vertical dives are simply breathtaking and are probably best appreciated with a camera because at least then, you can see how the bugger is doing it. He's actually flying on his back for much of the time but with his head in the normal position. I guess you could liken the display to one of those stunt biplanes except without the smoke.This unpaired male was doing its very best to attract a passing female, including building several nests in between display flights.
