To make the little bird leave, chuck something at it (7)
I believe the answer is:
gosling
'to make the little bird' is the definition.
I can't tell whether this definition defines the answer.
'leave chuck something at it' is the wordplay.
I cannot really see how this works, but
'leave' could be 'go' (to go is to depart or leave) and 'go' is found in the answer.
'chuck' could be 'sling' (chuck means throw as does sling) and 'sling' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gosling that I've seen before include "Young waterbird" , "Young goose" , "Young bird" , "Little bird" .)
