leaving their winter homes, the full plumage is assumed by a 

 moult. 



The adult female in winter plumage may bq distinguished by the 

 less amount of white on the tail and the dusky ear-coverts, as well 

 as the generally browner plumage above ; the throat is deep yellow. 



The flanks are always strongly marked with black stripes in 

 winter ; but are more pronounced in the males than in the females. 

 An interesting specimen from the Gould collection shows the as- 

 sumption of the rich spring plumage by a complete moult. 



Hah. United States, chiefly the eastern province, west to Utah 

 and New Mexico. Breeds in the northern portions of the United
