en for
any other because of the long slender neck and the long pointed bill,
which has a slight upward turn. They nest abundantly in the marshes of
North Dakota and central Canada. Their nests are made of decayed rushes,
and are built over the water, being fastened to the rushes so that the
bottom of the nest rests in the water. The nesting season is at its
height during the latter part of May. They lay from three to five eggs,
the ground color of which is a pale blue; this color is, however, always
concealed by a thin chalky deposit, and this latter is frequently
stained to a dirty white. Size 2.40 x 1.55.

2. HOLBOELL'S GREBE. _Colymbus holboellii._

Range.--Throughout North America, breeding from northern United States
northward and wintering from the middle to the southern portions of the
United States. In regard to size this Grebe comes next to the Western,
being 19 in. in length. This bird can be distinguished by the white
cheeks and throat and the reddish brown foreneck. They breed abundantly
in the far north placing their floating islands of decayed vegetation in
the water in the midst of the marsh grass. They lay from three to six
eggs of a dingy white color which have the stained surface common to
Grebes eggs. Size 2.35 x 1.25.

3. HORNED GREBE. Colymbus auritus.

Range.--The whole of North America, breeding in the interior from North
Dakota northwest; winters along the Gulf Coast. This species is one of
the most beautiful of the Grebes, having in the breeding season buffy
ear tufts, black cheeks and throat, and chestnut neck, breast and sides.
They breed abundantly in the marshy flats of North Dakota and the
interior of Canada. They build a typical Grebe's nest, a floating mass
of decayed matter which stains the naturally white eggs to a dirty
brown. The number of eggs varies from three to seven. Size 1.70 x 1.15.
Data.--Devils Lake, N. Dakota, June 20, 1900. 6 eggs much stained. Nest
floating in 4 ft. of water, a large mass of rotten rushes and weeds.
