TOTTPALMATE SWIMMERS 
119. Cormorant. Phalacrocorax carbo. 
Range. — The Atlantic coast breeding from Maine 
to Greenland. 
The common Cormorant or Shag is one of the 
largest of the race, having a length of 36 inches. 
In breeding plumage, the black head and neck 
are so thickly covered with the slender white 
plumes as to almost wholly obscure the black. 
There is also a large white patch on the flanks. 
They nest in colonies on the rocky shores of New- 
Chalky greenish or bluish whitae 
foundland and Labrador, placing their nests of 
sticks and seaweed in rows along the high 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 dur- 
ing 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. 
Cormorant 
Double-crested Cormorant 
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 carlo, 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 carlo 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.
