It is an interesting fact that the last migrants to 
leave in the fall are the first to arrive in the spring. 
The bird-life of November, when the fall migra- 
tion is practically concluded, closely resembles, there- 
fore, that of March, when the spring migration is 
inaugurated. : 
The reason for this similarity is to be found in 
the fact that both months furnish birds with essen- 
tially the same kind of food. Thus the Loon, Grebes, 
Ducks, Geese, and Kingfisher remain until Novem- 
ber or early December, when the forming of ice de- 
prives them of food and forces them to seek open 
water. Woodcock and Snipe linger until they can 
no longer probe the frost-hardened earth; but the 
thaws of March will bring all these birds back to us 
by restoring their food.
