One admired new bird (5)
I believe the answer is:
heron
'bird' is the definition.
(I know that heron is a type of bird)
'one admired new' is the wordplay.
'one admired' becomes 'hero' (I've seen this before).
'new' becomes 'n' (abbreviation as in New Testament NT).
'hero'+'n'='HERON'
(Other definitions for heron that I've seen before include "Graceful grey bird with long neck" , "Wading bird with long neck and legs" , "Large British wading bird" , "Wader" , "One bird" .)
