Wildfowl regularly seen as an object of admiration (4)
I believe the answer is:
idol
'an object of admiration' is the definition.
(I've seen this in another clue)
'wildfowl regularly seen' is the wordplay.
'regularly seen' indicates alternate letters.
The alternating letters of 'wildfowl' are 'IDOL'.
'as' acts as a link.
(Other definitions for idol that I've seen before include "Object of excessive adoration" , "Pop - - (TV)" , "'There's a one-eyed yellow -' (Hayes)" , "Subject of adoration, may be graven" , "Someone much loved" .)
