Bird reputed to be wise (3)
I believe the answer is:
owl
'bird reputed to be wise' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for owl that I've seen before include "Lear's loved a Pussy-cat" , "Pussy-cat's wooer (Lear)" , "Nocturnal bird of prey" , "Bird of prey with front-facing eyes" , "Member of Parliament" .)
