trouble will be greatly lessened. In every species there is a more or less 

 decided ochraceous tinge to the crissal region (sometimes extending forward 

 over the flanks) ; except in crissalis, in which the lower tail-coverts and anal 

 region are deep cliestnut. In autumn and winter this ochraceous tint be- 

 comes very much deeper, as well as more prevalent, than in spring and 

 summer ; the whole plumage becomes softer, the colors more pronounced, 

 and the markings more distinct, than when faded and worn in summer.
