LESSER SCAUP DUCK.
149. Marila affinis. 17 inches.
Slightly smaller than the last, and with the head of the male glossed purple instead of green on the black. They are one of the most abundant migrants, and are one of the most active of the family, diving at the flash of a gun. The immense flocks generally keep out in the open waters of the lakes or rivers; where they feed by diving.
Nest.—Is made of marsh grasses and neatly lined with feathers from the breast of the female. 6 to 9 eggs of a pale gray color (2.25 × 1.55).
RING-NECKED DUCK.
150. Marila collaris. 17 inches.
In appearance and general habits this duck is much the same as the two preceding. Male with head, neck and breast black with purple shades, having a ring of chestnut about the neck, which at a little distance is not noticeable. Bill blackish, with a bluish band near the end; eye yellow.
Nest.—Same in every way as above, and general distribution the same, breeding from Oregon and Minnesota northward.
