The Violet-green Swallow is a 

 strikingly beautiful bird both in form 

 and coloring. Although its plumage 

 lacks somewhat of the lustre of 

 the other swallows, the bright 

 green-and-violet effects of the 

 upper parts render it 

 unique among its kind. 

 It is a lover of pine 

 woods and mountain for- 

 ests, but where these 

 are scarce, it makes its 

 home among the bare 

 cliffs, nesting in crev- 

 ices in the rocks. In 

 California all of the nests 

 I have found have been in de- 

 serted woodpecker excavations 

 which the Swallows had filled 

 with feathers and bits of grass.
