Look for male bird (6)
I believe the answer is:
gander
I believe this is a double definition.
'look' is the first definition.
(informal term for a look or glance)
'male bird' is the second definition.
(male goose)
'for' is the link.
(Other definitions for gander that I've seen before include "Butchers - goose" , "male member of the Anatidae family" , "A butcher's -- bird" , "Bird from Newfoundland airport" , "Glimpse" .)
