Spooner's heavy bird of prey in kerfuffle (8)
I believe the answer is:
catfight
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for catfight that I've seen before include "misses rowing?" , "Battle between felines" , "Bitter dispute (between moggies?)" , "Scrap between women" , "quarrel" .)
