6 BIRDS OF NORTH DAKOTA 



at this season. Many hunters seem to delight in shooting them at this season 

 of the year from pure wantonness apparently. As they are useless for food 

 and require no skill to get them, this is a deplorable habit, for they are very 

 beneficial as insect destroyers. No records of their nesting here, but have heard 

 of a large colony breeding near Devils Lake.
