Range.— Coast of tlie North Pacific, wintering 

 soutli to California. 



The Pacific Kittiwake breeds in immense rook- 

 eries on some of the islands in Bering Sea. They 

 are well distri])uted 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.

 latitudes. 



This Kittiwake is similar to the preceding, with 

 the exception that the legs are bright red, the

 species was found by Dr. Leonard Stejneger to be 

 a very abundant nesting bird on islands in Ber-

Ked-legged Kittiwake 



Glaucous Gull Brownish buff 



ing 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. Tlie ground color 

 of the eggs is buffv or brownish, and the spots are dark brown and lilac. 

 Size 2.15x1.50. 



h2. Glaucous Gull. Lams hijpcrhoreus. 



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 2ird 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, Green- 

 land, 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 x 2.20.
