This Swallow is the most beautiful and grace- 

 ful of the family, and is a familiar sight to everyone, skimming over the mead- 

 ows and ponds in long graceful sweeps, curves and turns, its lengthened outer 

 tail feathers streaming behind. Throughout their range, they nest in barns, 

 sheds or any building where they will not be often disturbed, making their nests 

 of mud and attaching them to the rafters; they are warmly lined with feathers 

 and the outside is rough, caused by the pellets which they place on the exterior. 



Before the advent of civil- 

 ized man, they attached their 

 nests to the sides of caves, 

 in crevices among rocks "and 

 in hollow trees, as they do 

 now in some localities. Their 

 eggs cannot be distinguished 

 from those of the Cliff Swal- \n'
