More than one bird charges around church (7)

I believe the answer is:

finches

I'm a little stuck... Click here to teach me more about this clue!

'more than one bird' is the definition.
(finch is a kind of bird)

'charges around church' is the wordplay.
'charges' becomes 'fines' (I can't explain this - if you can you should believe this answer much more).
'around' indicates putting letters inside.
'church' becomes 'ch' (common abbreviation).
'fines' enclosing 'ch' is 'FINCHES'.

Can you help me to learn more?

(Another definition for finches that I've seen is " Numerous small songbirds".)

I've seen this clue in The Telegraph.
