Male goose’s look (6)
I believe the answer is:
gander
I believe this is a double definition.
'male goose's' is the first definition.
(I've seen this before)
'look' is the second definition.
(informal term for a look or glance)
(Other definitions for gander that I've seen before include "Male goose - quick look" , "waterbird" , "Looking at something - ranged (anag)" , "Male goose; look (colloq.)" , "He has webbed feet" .)
