It is an interestino: fact that the last mio^raiits to 

 leave in the fall are the lirst to arrive in the spring. 



The bird-life of JS^ovember, 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 Xovem- 

 l)er or early December, when the forming of ice de- 

 prives them of food and forces them to seek open 

 water. A\7)odc()ck and Sni})e linger until they can 

 no longer prolje the frost-hardened earth; but the 

 thaws of March will bring all these birds back to us 

 l)y restoring their food.
