NONBREEDING MALE MALLARDS, PRESQ'ILE PROVINCIAL PARK, BRIGHTON, ON

   On the Mallard in front you can see the distictive speculum: blue-purple with black and white borders.  We can iD these Mallards as nonbreeding males by their yellow bills with a black dot (rather than the orange bills of the females) and by their grayish necks (rather than the green necks of breeding male Mallards).
