Ape, wolf, mongrel, and bird (7)
I believe the answer is:
peafowl
'bird' is the definition.
(peafowl is a kind of bird)
'ape wolf mongrel' is the wordplay.
'ape wolf' can be anagrammed to 'PEAFOWL'.
Though, I am unsure how this is indicated.
'and' is the link.
Can you help me to learn more?
(Other definitions for peafowl that I've seen before include "Large female bird" , "Peacock or peahen" , "Pheasant with fan-like tail" , "Ape, wolf (anag.)" , "Large crested pheasant" .)
