Philippe,

Your Hawk 9174 is an excellent example of the way birds of prey use their 
wingtip feathers to control their lift and speed, allowing them to hover and 
watch for the next target.  He obviously found one.

When I was in college, back in another lifetime, the Aerophysics Dept. had a 
government contract to study wingtip improvements on airplanes.  Dr. Gus 
Raspet trained a buzzard to fly alongside his glider, so that he could 
observe and photograph the wings.
