THE BIRD-LIFE OF A YEAR. 17 
The migratory movement rapidly grows in 
strength, and, during the latter part of the month, 
one inay 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.
