throat-pouch, of a vivid red color, gives a grotesque effect to the 

 otherwise somber colored male Man-o'-War Bird. The back-

A Klamath Lake Bird Colony. Background by Carlos Hittell. 

 Birds by Herbert Lang. — Klamath Lake, on the California-Oregon 

 boundary line, is a vast expanse of shallow water, broadly bordered 

 with tules and rushes, and studded with low small islets covered 

 with vegetation similar to that of the shores. It is thus a favorite 

 breeding resort for a great variety of water birds, among which are 

 the White Pelican, the California and Ring-billed Gulls, Caspian 

 Tern, Farallone Cormorant, Great Blue and Black-crowned Night 

 Herons, Wild Geese, the Bufflehead and other species of Ducks. 

 The birds shown in the group are the White Pelican (old birds and 

 young, nests and eggs), the Western Gull, Caspian Tern (numerous 

 individuals of each), and the Farallone Cormorant. The scene is 

 a tule island, with similar small islands in the immediate back- 

 ground, treeless hills beyond, and snow-capped, grand Mount 

 Shasta in the distance.
