Default AERODYNAMICS OF GLIDING FLIGHT IN A HARRIS' HAWK

Doug,

That is really pretty good for an accipiter that catches song birds in
flight. I wonder what they would come up with on one of the soaring raptors
(Swainson, Red Tail, Golden Eagle, Turkey Vulture, etc.)

Stumbled across an interesting wind tunnel test of a Harris' Hawk
(L/D=10:1).

They had a polar comparison with a Black Vulture, but it was not as
good, sort of like the 1-26 of raptors? ;-)

OK, before you flame me, I did my Diamond Goal in a 1-26 (twice).
