Our knowledge ul" llie feeding: luibils of lliis spccu'S is 

 unusually complete. Besides the isolated observations of a 

 large number of competent observers, we have tlie results of 

 the special studies of Dr. B. H. Warren, in wliich the con- 

 tents of one hundred and seventy-three stomachs were ex- 

 amined, and Dr. A. K. Fisher, who studied five hundred and 

 sixty-two stomachs from twenty-six widely separated States, 

 Territories, and l^rov- 

 inces, ranging from 

 Ontario to Florida and 

 Massachusetts to Califor- 

 nia. Dr. Warren found 

 mice in one hundred and 

 thirty-one of the one 

 hundred and seventy- 

 three stomachs he ex- 

 amined, while six of 

 them contained rabbits ; 

 three, red squirrels ; 

 two, skunks ; and eigh- 

 teen, small birds. Poul- 

 try was found in four 

 specimens, insects in 

 three, snakes in three, 

 and carrion in four. 

 Thus, less than ten per 

 cent, of the birds had 

 eaten poultry. Dr. 



Fishers results as to ponltry were similar ; fifty-four out of 

 the five hnndred and sixty-two specimens contained i)onltry 

 or game-birds. Various other birds, as the robin, mourning- 

 dove, (TOW, shore-lark, king-rail, meadow-lark, oriole, blue- 

 bird, grackle, screech-owl, and several species of sparrows, 

 were found in iifty-one stomachs. Mice — including the house,
