gh ledges, where they sit, as one writer
aptly expresses it, like so many black bottles. A few pairs also nest on
some of the isolated rocky islets off the Maine coast. During the latter
part of May and during June they lay generally four or five greenish
white, chalky looking eggs. Size 2.50 x 1.40. Data.--Black Horse Rock,
Maine coast, June 6, 1893. Four eggs in a nest of seaweed and a few
sticks; on a high ledge of rock. Collector, C. A. Reed.

120. DOUBLE-CRESTED CORMORANT. _Phalacrocorax auritus auritus._

Range.--The Atlantic coast and also in the interior, breeding from Nova
Scotia and North Dakota northward.

This is a slightly smaller bird than carbo, and in the nesting season
the white plumes of the latter are replaced by tufts of black and white
feathers from above each eye. On the coast they nest the same as carbo
and in company with them on rocky islands. In the interior they place
their nests on the ground or occasionally in low trees on islands in the
lakes. They breed in large colonies, making the nests of sticks and
weeds and lay three or four eggs like those of the common Cormorant but
averaging shorter. Size 2.30 x 1.40. Data.--Stump Lake, North Dakota,
May 31, 1897. Nest of dead weeds on an island. Six eggs. Collector, T.
F. Eastgate.

120a. FLORIDA CORMORANT. _Phalacrocorax auritus floridanus._

This sub-species is a common breeding bird in the swamps and islands of
the Gulf coast and north to South Carolina and southern Illinois. The
nests are placed in the mangroves in some of the most impenetrable
swamps and are composed of twigs and lined with leaves or moss. They lay
three or four chalky bluish white eggs. Size 2.30 x 1.40. Data.--Bird
Is., Lake Kissimee, Florida, April 5, 1898. Three eggs. Nest made of
weeds and grass, in a willow bush.

120b. WHITE-CRESTED CORMORANT. _Phalacrocorax auritus cincinatus._

Range.--Northwestern coast of North America, breeding in Alaska, and
south to the northern boundary of the United States, breeding both in
the interior and on the coast, in the former case generally on the
ground or in low trees on swampy islands and in the latter, on the rocky
cliffs of the coasts and islands. The nests are built in the same
fashi
