This is a new species, first discovered in the state of 
Connecticut, and twice since met with in the neighbourhood 
of Philadelphia. As to its notes or nest, I am altogether 
unacquainted with them. The different specimens I have 
shot corresponded very nearly in their markings ; two of these 
were males, and the other undetermined, but conjectured also 
to be a male. It was found in every case among low thickets, 
but seemed more than commonly active, not remaining for a 
moment in the same position. In some of my future rambles 
I may learn more of this solitary species. 
Length, five inches and three quarters ; extent, eight 
inches ; whole upper parts, a rich yellow olive ; wings, dusky 
brown, edged with olive ; throat, dirty white, or pale ash ; 
upper part of the breast, dull greenish yellow; rest of the 
lower parts, a pure rich yellow ; legs, long, slender, and of a 
pale flesh colour ; round the eye, a narrow ring of yellowish 
white ; upper mandible, pale brown ; lower, whitish ; eye, 
dark hazel. 
Since writing the above, I have shot two specimens of a 
bird, which in every particular agrees with the above, except 
in having the throat of a dull buff colour, instead of pale 
ash ; both of these were females ; and I have little doubt but 
they are of the same species with the present, as their peculiar 
activity seemed exactly similar to the males above described. 
These birds do not breed in the lower parts of Pennsylvania, 
though they probably may be found in summer in the alpine 
swamps and northern regions, in company with a numerous 
class of the same tribe that breed in these unfrequented 
solitudes. 
* According to Bonaparte, this is a new species discovered by Wilson. 
Comparatively little is known regarding it. — Ed.
