cussed in Circular 32. While with us, the food of the Golden 

 Plover consists chiefly of grasshoppers and other insects. To-

Another of our wading birds, wrongly referred to frequently 

 as "Crane." The cranes, be it said, are rather birds of the plains 

 and prairies — not of wooded sections, where we find these fisher- 

 men abundantly represented. Its food consists of frogs and fish, 

 but grasshoppers and field mice are not scorned. Like the king- 

 fisher, it may become destructive when frequenting the ponds of 

 the fish-breeder.
