84 SWALLOWS 



crowd the wayside wires from pole to pole. At night, 

 with others of their tribe, they roost in the marshes. 



Tree Swallows they are called because they nest in 

 hollow trees and, like some other hole-nesting birds, they 

 may be induced to occupy nesting-boxes, making a 

 welcome addition to our list of bird tenants. The 4-7 

 white eggs are laid in May.

The Bank Swallow is a bird of the air who tunnels the 

 earth for a nesting-place. Where river or road has left a 

 bank, its face may be dotted with the entrances to the 

 Bank Swallow's dwellings. At the end of two or three 

 feet the nest of grass and feathers is placed, fit receptacle 

 for the pearl-white eggs, which are usually laid the latter 

 half of May. 



During the migrations the Bank Swallow travels with 

 other members of its family, sharing their roost in the 

 marshes by night and their wayside perch by day.
