WAXWINGS AND PHAINOPEPLAS 387 



Distribution. Northern hemisphere ; in America breeding from the 

 limit of trees south to the central United States ; wintering from the 

 southern border of the United States south to the West Indies, Central, 

 and northern South America. 



Nest. In horizontal holes or burrows, excavated in sand banks, cuts, 

 and banks of streams. Eggs : 3 to 6, white. 



Food. Insects. 



The colonies of chattering little bank swallows with dull colored 

 backs and dark chest bands seem to require little more than a sand 

 bank and a telegraph wire for complete happiness, and given these, 

 blow the wind east or blow the wind west, they gossip merrily on.

 Eggs : 3 to 6, white. 



Food. Flies and other insects. 



The dingy rough wings are less sociable than the bank swallows 

 during the nesting season, but afterwards assemble in large flocks 

 and are in less of a hurry to start for the south. 



In Nevada, during a shower, Mr. Oberholser once found a flock 

 congregated about a small cliff in a cave.
