I hear double container is for a brightly-coloured bird (6)
I believe the answer is:
toucan
'bird' is the definition.
(toucan is a kind of bird)
'i hear double container is for a brightly-coloured' is the wordplay.
I cannot quite understand how this works, but
'i' could be 'a' and 'a' is located in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for toucan that I've seen before include "Fruit-eating bird" , "A pair could be able for this bird, by the sound of it" , "Brightly-coloured tropical bird with large beak" , "Large-billed tropical bird" , "Bird with large, colourful bill" .)
