Parrot giving a masterly imitation of a crow? (5)
I believe the answer is:
macaw
'parrot' is the definition.
(type of parrot)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for macaw that I've seen before include "Type of parrot" , "Tropical bird" , "Large colourful parrot" , "Brightly-coloured parrot" , "colourful flyer" .)
