Its food consists of rubbits, squirrels, woodchucks and occusionully

The abundance of bird life in this western lake beneath ]\It. Shastti, 



which is seen in the center of the background, is astonishing. Here is an 



example of how the normul nesting hubits of a bird may be 

 „ changed by its being driven into u different locality. In 



the group are white pelicans which usually make a nest of 

 pebbles, Caspian terns which commonly build their nests on sand, and 

 cormorants that nest on rocks, all nesting together here on the tule or 

 rush islets of the lake. (Reproduced from studies at Klamath Lake, 

 Oregon.) 



The scene represented in this group is above timber line on the crest 



of the Canadian Rockies — 8,000 feet above the sea. Al- 

 Arctic-Alpine though these mountains are in the temperate region the 

 Group altitude gives climatic conditions that would be found in 



the far north, and the bird life is arctic in character. Here 

 are nesting the white-tailed ptarmigan, rosy snow^ finches and pipits. (Re- 

 produced from studies in the Canadian Rockies.) 



This group shows a stretch of western plateau covered with sage bush. 



In this bush is seen the male sage grouse strutting and wooing 

 P a mate. (Reproduced from studies at Medicine Bow, 



Wyoming.) 

 The prairie chickens are akin to the common grouse. The group 



represents a typical scene during the mating season. The

on the sides of their necks, dancing and strutting about and 

 uttering a loud, resonant, booming note. (Reproduced from studies near 

 Halsey, Nebraska.) 



The w^ild goose is one of the first birds to migrate north in the spring. 



It nests in the lakes of Canada even before the ice is melted. 

 P To secure the young birds for this group it was necessary 



to hatch the eggs of the wild goose under a hen, so difficult 

 is it to find the young in nature. (Reproduced from studies made at Crane 

 Lake, Saskatchewan, Canada.) 



The grebe is another of our aquatic birds which builds its nest near the 



water. During the incubation period the parent bird

the nest. Nesting at the same lake with the grebe was the
