Toreros carved up bird (7)
I believe the answer is:
rooster
'bird' is the definition.
(rooster is a kind of bird)
'toreros carved up' is the wordplay.
'carved up' is an anagram indicator.
'toreros' with letters rearranged gives 'ROOSTER'.
(Other definitions for rooster that I've seen before include "Early-morning caller" , "Adult male domestic fowl" , "One may crow" , "8 [RURAL] alarm call" , "Adult male chicken" .)
