Tropical American fruit-eating bird with a brightly coloured bill (6)
I believe the answer is:
toucan
(Other definitions for toucan that I've seen before include "arboreal dweller" , "Bird with large, colourful bill" , "A pair could be able for this bird, by the sound of it" , "Brightly-coloured tropical bird with large beak" , "Tropical American bird with immense beak" .)
