The bird hopping round (8)
I believe the answer is:
flamingo
'the bird' is the definition.
(flamingo is a kind of bird)
'hopping round' is the wordplay.
'hopping' becomes 'flaming' (I can't explain this - if you can you should give a lot more credence to this answer).
'round' becomes 'o' (round can mean a round object).
'flaming'+'o'='FLAMINGO'
Can you help me to learn more?
(Other definitions for flamingo that I've seen before include "Pink wader" , "Long-legged wader" , "Long-legged bird" , "Large pink bird" , "Pink flier" .)
