Bucks and does (4)
I believe the answer is:
deer
'bucks and does' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deer that I've seen before include "Ruminant mammal with antlers and hooves" , "Grazing animal(s)" , "The male is a stag" , "Hoofed mammal" , "The male has antlers" .)
