ey are well distributed over Copper Island where they
nest in June and July, choosing the high ledges which overhang the sea.
The nesting habits and eggs are precisely the same as those of the
common Kittiwake.

41. RED-LEGGED KITTIWAKE. _Rissa brevirostris._

Range.--Northwestern coasts, breeding in high latitudes.

This Kittiwake is similar to the preceding, with the exception that the
legs are bright red, the mantle is darker, and the bill is shorter. This
species was found by Dr. Leonard Stejneger to be a very abundant nesting
bird on islands in Bering Sea, selecting steep and inaccessible rocks
and ledges on which to build its nest. Their nesting habits are
precisely the same as the Pacific Kittiwake, but they most often nest in
separate colonies, but can be distinguished readily when nesting
together by the darker mantles when on the nest and the red legs when
flying. Grass, moss and mud are used in the nest. The ground color of
the eggs is buffy or brownish, and the spots are dark brown and lilac.
Size 2.15 x 1.50.

42. GLAUCOUS GULL. _Larus hyperboreus._

Range.--Arctic regions, south in winter to Long Island, the Great Lakes,
and San Francisco Bay.

This Gull shares with the Great Black-backed Gull the honor of being the
largest of the Gulls, being 28 inches in length. Mantle light gray; it
is distinguished by its size and the primaries, which are white to the
tips. A powerful bird that preys upon the smaller Gulls and also devours
the young and eggs of smaller birds.

They nest on the ground on the islands and shores of Hudson Bay,
Greenland, etc. The nest is made of seaweed, grass and moss and is
generally quite bulky. The two or three eggs are laid in June. They are
of various shades of color from a light drab to a brownish, and are
spotted with brownish and black. Size about 3.00 x 2.20.

42.1. POINT BARROW GULL. _Larus barrovianus._

Range.--Northwest coast from Bering Sea to Point Barrow.

This species is almost identical with the Glaucus Gull, averaging
perhaps a trifle smaller. Its standing as a distinct species is still
questioned and has not yet been decided satisfactorily. Early in June
their nests are built on remote islands in Bering Sea. These nests are
the same as the last species, large piles of vegetation, hollowed on top
for the reception of th
