Big-beaked bird (5)
I believe the answer is:
macaw
'big-beaked bird' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for macaw that I've seen before include "Tropical parrot" , "Avian chatterbox" , "Large colourful parrot" , "Long-tailed American parrot" , "colourful flyer" .)
