Bird, wolf and ape muddled (7)
I believe the answer is:
peafowl
'bird' is the definition.
(peafowl is a kind of bird)
'wolf and ape muddled' is the wordplay.
'and' means one lot of letters go next to another.
'muddled' is an anagram indicator.
'wolf' put after 'ape' is 'apewolf'.
'apewolf' anagrammed gives 'PEAFOWL'.
(Other definitions for peafowl that I've seen before include "Peacock or peahen" , "Pheasant with fan-like tail" , "Large female bird" , "Large crested pheasant" , "Ape, wolf (anag.)" .)
