BIRDS OF ESSEX COUNTY. 289 



269 [647] Helminthophila peregrina (Wils.). 

 Tennessee Warbler. 



Very rare transient visitor; May 23 and September. 



There are two undated specimens in the collection of the Peabody Academy, 

 from Essex County, obtained by S. Jillson. Mr. W. A. Jeffries reports one as 

 seen by Mr. Walter Faxon and himself at Swampscott on May 23d, 1891. 



270 [648a] Compsothlypis americana usneae Brewst. 

 Northern Parula Warbler. 



Abundant transient visitor, rare summer resident ; May 2 to May 30 ; June, 

 July; September 10 to October 10. 



The Usnea "moss" that is needed for this bird's nest is to be found in 

 various parts of the County. I have found the birds in Magnolia during June 

 and July, and noted one as singing on July 4th, 1877. Mr. H. A. Purdie tells 

 me that he has heard them in the breeding season in Essex. I have, however, 

 no actual record of their nesting. 



271 [650] Dendroica tigrina (Gmel.). 

 Cape May Warbler. 



Rare transient visitor ; May; August 18 to September. 



There is a specimen of the Cape May Warbler in the collection of the 

 Boston Society of Natural History, labeled Lynn, which is perhaps the one 

 recorded by Putnam 1 as taken in Lynn in 1847, by Jillson. At the Peabody 

 Academy are two specimens from Essex County, one taken August 1 8th, 1 880, 

 the other in May, 1878.
