     I hate to sound stupid, but do body contour feathers serve a 
practical purpose in a flying animal, not just as thermoregulation for 
endotherms?  I guess I am thinking about the cooling effect of the fast 
passage of an animal through the air, and how it might be good to have 
insulation to keep from getting chilled.
