DENDEGECA COEONATA, {Linn.) Gray. 



Yellow-rumped Warbler. 



Not observed until about the middle of September, when, during the 

 fall migration, it made its appearance in abundance along the Mouse 

 Eiver, in company with the Snowbirds and other species just come from 

 the north. It is one of the Warblers which, though distinctively belonging 

 to the Eastern Province, occasionally straggles southward by a direct 

 line from the extreme western points which it reaches in Alaska. Drs. 

 Cooper and Suckley found it in Washington Territory; Dr. Hayden, up 

 the Missouri to above old Fort Pierre; and Mr. C. E. Ail;en, Mr. T. M. 

 Trippe, and Mr. H. W. Henshaw have each found it in Colorado Terri- 

 tory. Its breeding-range is not a little remarkable : it has been recorded 

 as breeding in Jamaica, as well as in various parts of British America 

 and Alaska, but is not known to nest in the greater part of the inter- 

 vening country. Similarly, in winter, some individuals endure the 

 rigors of the Middle, if not of some of the Northern, States, while others 

 press on into Central America. No other Warbler, as far as kno\\ u, has 

 such a peculiar distribution as this.
