Nibbling at the scrap put out, is taking flight (7,2)

'nibbling at the scrap put out' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'taking flight' is the wordplay.
I cannot quite understand how this works, but
'taking' could be 'eating' (eating is a kind of taking) and 'eating' is found within the answer.
The remaining letters 'bit' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'is' acts as a link.

Can you help me to learn more?
