The Birds and Poets l8l 



some deer in the extreme north migrate southward 

 in winter. As with the birds, the two most com- 

 pelling influences in inducing these migrations are 

 the instinct for reproduction and the desire for 

 food. 



By the end of October, all of the true migrants 

 save a few stragglers have gone to their winter 

 homes in the south, and the lonesome bird lover 

 begins to feel with Lowell that 



"Autumn's here, and Winter soon will be. 

 Who snows his soft, white sleep and silence over all.'
