Whooping Crane. This is the largest bird in the United 

 States, measuring four feet from tip of bill to tip of tail, 

 from seven to eight feet from tip to tip of the wings and 

 standing nearly as tall as a man. The group shows the 

 birds as they doubtless once appeared on the shores of 

 Heron Lake, Minnesota, a region they are known to have 

 inhabited. 



Golden Eagle. The natural food of the golden eagle in 

 the west consists chiefly of small mammals, such as prairie 

 dogs, rabbits and squirrels, but also of ducks and grouse. 

 Occasionally it takes a young deer or antelope. On the 

 whole, however, it is a beneficial bird because of the large 

 number of rodents it destroys. Where sheep have been in- 

 troduced it may become more or less injurious through its 

 acquired habit of preying on lambs. It differs from the 

 bald eagle, the common eagle of the eastern states, in color 

 and in having the legs feathered quite to the toes. Repro- 

 duced from studies made at Bates's Hole, fifty miles north 

 of Medicine Bow, Wyoming. 



A Klamath Lake Bird Colony. On the borders of Kla- 

 math Lake, situated in northeastern California on the Ore- 

 gon boundary line, a number of colonies of white pelicans, 

 California and ring-billed gulls, terns, cormorants and blue 

 herons have established their nests. The group shows the 

 border of a tule island in the Lake, while in the background
