This species was first described by Mr. Cassin, in 1851, from 
a specimen shot by him near Philadelphia in 1842. The bird’s 
habits remain almost unknown. The only nest yet discovered was 
found by Mr. Ernest E. Thompson in Manitoba. 
Of the bird’s range very little is known. A few examples have 
been taken in New England, and in 1882 our party secured several 
at Edmundston, in New Brunswick, near the Quebec border. Dr. 
Wheaton considered it a regular spring and fall migrant through 
Ohio, but very few have been observed in Ontario. 
Note. — Mr. Comeau has taken at Godbout, on the north shore 
of the Gulf of St. Lawrence, one example of the YELLOW-GREEN 
VIREO (V. flavovirides), a bird of Mexico and Central America.
