DESCRIPTION. 
Top and sides of the head and neck ash-gray; 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 
from 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. 
Mr. Geo. A. Boardman says in the Am. Naturalist that a 
few remain in his locality (Calais, Me.) through the season, 
from which I judge that it breeds there.
