The son shrugs off noisy creatures (4,8)

I believe the answer is:

song thrushes

'noisy creatures' is the definition.
'song-thrushes' can be an answer for 'creatures'. I also know that 'noisy' relates to this answer.

'the son shrugs off' is the wordplay.
'off' indicates anagramming the letters.
'the'+'son'+'shrugs'='thesonshrugs'
'thesonshrugs' with letters rearranged gives 'SONG-THRUSHES'.

I've seen this clue in The Everyman puzzle in The Observer.
