Creator with intelligence makes a bird (6)
I believe the answer is:
godwit
'a bird' is the definition.
(godwit is a kind of bird)
'creator with intelligence' is the wordplay.
'creator' becomes 'god' (the creator can mean God).
'with' is a charade indicator (letters next to each other).
'intelligence' becomes 'wit' (wit is a kind of intelligence).
'god'+'wit'='GODWIT'
'makes' acts as a link.
(Other definitions for godwit that I've seen before include "Long-legged northern shore bird" , "Wader; do twig (anag.)" , "Large wading bird" , "Wader; two dig (anag.)" , "Flyer" .)
