The Migration of North American Birds 



323 



Although rather an early spring migrant, this Swallow is late in leaving its 

 winter home, and stragglers linger in the southeastern United States long after 

 the vanguard of its northern movement has penetrated far into Canada. The 

 first list given below, under the head of spring migration, includes the dates of 

 departure from the winter home of the species, and the second, the dates of 

 arrival in its summer home. Conversely, under the fall migration, the first list 

 gives the dates of departure from the summer range, and the second, of arrival 

 in its place of winter sojourn.
