order to preserve the crop from their depredations, at least if the grain 

 is still in the milk. It has been estimated by the Biological Survey experts 

 that millions of dollars damage is done every year to the rice crop of 

 the South by the Ricebird, as he is invariably called in the southern states. 

 The Bobolink does not remain in the rice states, but before he has left 

 sometimes a large portion of the planters' income has been destroyed. 

 Therefore, more than any of our native species, he has a double reputation, 

 being perhaps our most favorite songbird in the northern states and the 

 most dreaded of all the small birds of America in the southern states.
