THE BIRD-LIFE OF A YEAR. 



17 



The migratory movement rapidly grows in 

 strength, and, during the latter part of the month, 

 one may expect to see new comers almost daily. 



It will be noted that the earlier migrants of the 

 month are all seed-eaters, who return just in time to 

 help the remaining Winter Visitants harvest what is 

 left of the preceding year's crop of seeds. Later, 

 certain insectivorous birds which catch their prey 

 on the wing are found ; for example, the Swallows, 

 Swift, and Nighthawk.
