on as the other Cormorants, and the three to five eggs are similar.
Size 2.45 x 1.40.

120c. FARALLON CORMORANT. _Phalacrocorax auritus albociliatus._

Range.--This sub-species breeds on the coasts and islands of California
and southward.

In company with other species of Cormorants, these birds breed in large
numbers on the Farallones, placing their nests well up on the higher
ridges and rocks. They breed most abundantly during May. When nesting on
the inland islands, they place their nests in low bushes. Their nests
and eggs are similar to those of the other Cormorants. Size 2.40 x 1.50.
Data.--Farallones, California. Nest of weeds and seaweed on the rocks.
Collector, W. O. Emerson.

121. MEXICAN CORMORANT. _Phalacrocorax vigua mexicanus._

Range.--Breeds abundantly from southern Texas, south through Mexico;
north rarely to Kansas; has recently been found breeding in limited
number on some of the Bahamas. In the interior they nest in trees,
chiefly those overhanging or growing in the water. On the coasts they
nest on the rocky ledges, as do the other Cormorants. They nest in
colonies building their abode of twigs and weeds, and during May laying
three or four eggs, greenish white in color and chalky, as are all the
Cormorants. Size 2.25 x 1.35.

122. BRANDT'S CORMORANT. _Phalacrocorax penicillatus._

Range.--Pacific coast breeding along the whole coast of the United
States.

This species is found more abundantly on the Farallones than is the
Farallone Cormorant. Like the other Cormorants breeding on these
islands, these cling closely to their nests, for fear of being robbed by
the Gulls, that are ever on the watch to steal either eggs or young.
Their nesting habits and eggs are identical with those of the other
species. Size 2.50 x 1.50. Data.--Bird Island, California, May 24, 1885.

123. PELAGIC CORMORANT. _Phalacrocorax pelagicus pelagicus._

Range.--Coast of Alaska.

These are perhaps the most beautiful species of Cormorants, having
brilliant violet green metallic reflections and, in the breeding
plumage, crests on the forehead and nape, as well as large white flank
patches. They breed in large colonies on the Aleutian Islands, placing
their nests of sticks and sea mosses on the rocky ledges, often hundreds
of feet above the sea level. Three o
