Hoods for cold birds (5)

I believe the answer is:

cowls

'hoods' is the definition.
('cowl' can be a synonym of 'hood')

'cold birds' is the wordplay.
'cold' becomes 'C' (eg on taps).
'birds' becomes 'owls' (owl is a kind of bird).
'c'+'owls'='COWLS'

'for' acts as a link.

(Other definitions for cowls that I've seen before include "Coverings" , "Monks' hoods" .)

I've seen this clue in The Telegraph.
