Bloody duck — its neck’s all pink! (8)
I believe the answer is:
flamingo
'its neck's all pink' is the definition.
I can't tell whether this definition defines the answer.
'bloody duck' is the wordplay.
'bloody' becomes 'flaming' (synonyms).
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'flaming'+'o'='FLAMINGO'
Can you help me to learn more?
(Other definitions for flamingo that I've seen before include "Pink wader" , "Large pink bird" , "Tall wading bird" , "Pink flier" , "Pretty bird" .)
