Bird torero's cooked (7)
I believe the answer is:
rooster
'bird' is the definition.
(rooster is a kind of bird)
'torero's cooked' is the wordplay.
'cooked' indicates an anagram.
'toreros' anagrammed gives 'ROOSTER'.
(Other definitions for rooster that I've seen before include "Farmyard fowl" , "Adult male chicken" , "So retro (anag.)" , "Bird that wakes up" , "Morning caller" .)
