The adult female is like the male in plumage. 



In the nesting-season the spots at the tips of the wing-coverts 

 become much abraded, as do also the feathers of the face, which 

 becomes more ashy grej'. Youvr/ hinls resemble the adult, but are 

 more dingily coloured, and have dingy black spots on the feathers 

 of the upper surface ; the spots on the lower surface of the bod)' are 

 also much smaller and less distinctly indicated. 



The Ero wn Thrasher inhabits the eastern province of Xorth 

 America to the Missouri lliver and north to Lake Winnipeg. In the 

 plains between the Missouri River and the Rocky Mountains along- 

 tailed race {H. lomjicaudus) was supposed to exist ; but it is now 

 stated that every intermediate form between this race and true //. 

 rufus can be found, and therefore no specific distinctions between 

 them can be upheld. It has occurred once in Heligoland.
