 Like a Zero fighter coming in at full throttle, the wood-swallow swoops in on the eagle, seemingly screaming its lungs out. 
The eagle's expression appears of utter surprise - I'll have the same reaction too if I were chased by a much smaller creature.
 |  IMG_8714.JPG
 The wood-swallow overshoots its target, as if it were a supersonic fighter jet attacking a slow, lumbering bomber. | 
|  IMG_8717.JPG
 A momentary lull in the action, as the wood-swallow gets out of the frame to do an inverted loop maneuver. |  IMG_8718.JPG
 After the inverted loop, the pesterer attacks from behind in a classic dogfighting tactic. The raptor, seemingly surprised once more, can only manage a puzzled look. |  IMG_8719.JPG
 The wood-swallow, like a speeding bullet, again overshoots the raptor. 
This time, the larger bird got the message and just flew away... possibly in search of safer adversaries, like snakes and lizards...;-)
