Flier's hush money presented on time (9)

I believe the answer is:

shorebird

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

'flier's' is the definition.
(shorebird is a kind of birdanimal)

'hush money presented on time' is the wordplay.
'hush' becomes 'sh'.
'money' becomes 'ore' (I have seen 'foreign money' mean 'ore' so perhaps 'money' could also mean 'ore').
'presented on time' becomes 'bird' (I can't justify this - if you can you should believe this answer much more).
'sh'+'ore'+'bird'='SHOREBIRD'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
