THE BIRD-LIFE OF A YEAR. 



About September 25, our more common Winter 

 Visitants arrive from the north, and after that date 

 birds rapidly decrease in number. 



Few songs are heard during the month ; the 

 characteristic bird-notes being the sharp kee-yer of 

 the Flicker, and the calls of Blue Jays gathering 

 their autumn toll from the chestnut trees.
