Big city accommodating strange bird (5)
I believe the answer is:
noddy
'bird' is the definition.
(I've seen this before)
'big city accommodating strange' is the wordplay.
'big city' becomes 'NY' (New York).
'accommodating' indicates putting letters inside.
'strange' becomes 'odd' (I've seen this before).
'ny' enclosing 'odd' is 'NODDY'.
(Other definitions for noddy that I've seen before include "Enid Blyton character" , "Blyton character - tern" , "Big Ears' pal" , "Sea bird" , "Blyton's Toytown boy" .)
