That woman no different to a bird (5)
I believe the answer is:
heron
'a bird' is the definition.
(heron is a kind of bird)
'that woman no different' is the wordplay.
'that woman' becomes 'her' (I've seen this before**).
'different' indicates an anagram.
'no' is an anagram of 'on'.
'her'+'on'='HERON'
'to' is the link.
(Other definitions for heron that I've seen before include "Tall wading bird" , "flier" , "Big bird" , "Large fish-eating bird" , "Wading bird with long neck and legs" .)
