question. The locality of the nests was a mossy bank, at the edge 

 of young woods, sloping southward, and covered with bushes and 

 coarser plants."

The Tennessee Warbler. 



Sylvia peregrina, Wilson. Am. Oru., III. (1811) 83. Aud. Orn. Biog., II.

Sykia {Dac/ils) peregrina, Nuttall. Man., I. (1832) 412. 



Desceiption. 



Top and sides of the head and neck ash-gi-av ; rest of upper parts olive-green, 

 brightest on the rump; beneath dull-white, faintly tinged in places, especially on the 

 sides, with yellowish-olive; eyelids and a stripe over the eye whitish; a dusky line 

 fi'om the eye to the bill; outer tail feather with a white spot along the inner edge, 

 near the tip. Female, with the ash of the head less conspicuous; the under parts 

 more tinged with olive-yellow. 



Length, four and fifty one-hundredths inches ; wing, two and seventy-five one- 

 hundredths; tail, one and eighty-five one-hundredths inches. 



This bird is an extremely rare summer visitor in New 

 England. Mr. Allen says he has taken it on Sept. 19 and 

 May 29 : this shows that it passes north to breed, but where 

 it passes the season of incubation we are ignorant. The 

 species itself seems to be a very small one ; and, as the mem- 

 bers are so few, they may be easily overlooked in the 

 forest through the whole season, particularly as they are 

 quiet and retiring in habits. I think that, perhaps, the 

 wilder sections of Maine and New Hampshire may give it a 

 summer home, but of course can only judge from the above 

 reasons. 



Of its nest and eggs I am ignorant ; and, as I have seen 

 no description of them, I can give none here.
