28 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 keb-yer of 
the Flicker, and the calls of Blue Jays ate 
their autumn toll from the chestnut trees.
