182 BIRDS OF FIELD, FOREST AND PARK 



The throat, sides of the head, and breast are 

 black, the belly white, the sides black and 

 white. The dress of the female is quite different, 

 rendering her rather difficult of identification. 

 The upper parts are olive-green with a bluish

 Minnesota and Massachusetts northward to

 streaked with black. The best field marks are 

 the yellow cheeks, white spots on the tail and
