Act as a proud bird might and find new things to do (6,4,5)
I believe the answer is:
spread ones wings
'find new things to do' is the definition.
(to spread one's wings is to start doing new things)
'act as a proud bird might' is the wordplay.
I cannot really see how this works, but
'act' could be 'swing' (swing is a kind of act) and 'swing' is found in the answer.
'a' could be 'one' and 'one' is found in the answer.
The remaining letters 'spreads' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for spread ones wings that I've seen before include "Develop abilities fully" , "as a high-flyer would?" , "make full use of one's talents" , "Try something new" .)
