A CHAPTER IN THE LIFE OF THE CANADA JAY. 



BY OSCAR BIRD WARREN. 



On the 22d of February of this year (1898), while returning 

 from a walk to a lumber camp near Mahoning, Mich., I dis- 

 covered a pair of Canada Jays {Perisoreus canadensis) building a 

 nest. 



1 Eight of sixteen specimens have the breast more or less washed with buff.
