preceding, chiefly by its size which
is about two inches less, or 17 inches in length. The nesting habits are
the same as those of the Greater Scaup and the eggs are similar but
smaller. Size 2.25 x 1.55. Data.--Northern Assiniboia, June 10, 1901.
Ten eggs on grass and down at the edge of a lagoon. Collector, Walter
Raine.

150. RING-NECKED DUCK. _Marila collaris._

Range.--North America, breeding in the interior, from North Dakota and
Washington northward. Winters from Maryland on the east and British
Columbia on the west to Central America.

Similar to the Lesser Scaup in size and plumage, except that it has a
narrow chestnut collar around the neck, the back is black instead of
barred with white, and the speculum is gray instead of white. The habits
and nesting habits of the Ring-neck do not differ from those of the
other Scaups. They lay from six to twelve eggs. Size 2.25 x 1.60.
Data.--Cape Bathurst, N. Y. T., June 18, 1901. Ten eggs in a slight
hollow in the moss, lined with down. Collector, Captain Bodfish.

151. GOLDEN-EYE. _Clangula clangula americana._

Range.--North America, breeding both on the coast and in the interior,
from the northern border of the United States northward to the Arctic
Ocean.

These are handsome Ducks known as "Whistlers" from the noise of their
wings when flying, and "Greatheads" because of the puffy crest. The head
is greenish with a large round white spot in front of, and a little
below the eye. The rest of the plumage is black and white. This species
nests in hollow trees near the water, lining the cavity with grass, moss
and leaves, and lining the nest with down from their breasts. In May and
June they lay from six to ten eggs of a grayish green color. Size 2.30 x
1.70.

152. BARROW'S GOLDEN-EYE. _Clangula islandica._

Range.--Northern North America, breeding north of the United States
except from the mountainous portions of Colorado northward.

This Golden-eye differs from the preceding chiefly in the shape of the
white spot before the eye, which in this species is in the form of a
crescent. The size is the same, about 20 inches in length. The
reflections on the head are purplish rather than greenish as in the
preceding. The nesting habits are the same, they building in hollow
trees near water. The six to ten
