I've suggested earlier on this list that such feathers would be extremely
advantageous in hunting and combat--a derivitive of the display and
fighting hypothesis published earlier by Richard Cowen and Jere Lipps.
Birds such as the roadrunner and the caracara use their wing and tail
feathers to fluster prey and to enhance mobility during combat--and
almost all birds fight on the ground. And it's the tail and forearm
feathers that appear most modified in the recent Chinese
specimens--particularly Caudipteryx. As Cowen pointed out, such flapping
during combat or display is ideal pre-flight training--and all at
essentially zero ground speed.
