CARBONATED SWAMP - WARBLER. 
Helinaia carbonata, Aud. 
PLATE OIX.— Males. 
I shot the two little birds here represented, near the village of Henderson, 
in the State of Kentucky, in May 1811. They were both busily engaged 
in searching for insects along the branches and amongst the leaves of a 
dogwood tree. Their motions were those common to all the species of the 
genus. On examination, they were found to be both males. I am of opinion 
that they were each young birds of the preceding year, and not in full 
plumage, as they had no part of their dress seemingly complete, excepting 
the head. Not having met with any other individuals of the species, I am 
at this moment unable to say any thing more about them. They were 
drawn, like almost all the other birds which 1 have represented, immediate- 
ly after being killed ; but the branch on which you see them was not add- 
ed until the following summer. 
The common name of this plant is service-tree. It seldom attains a greater 
height than thirty or forty feet, and is usually found in hilly ground of 
secondary quality. The berries are agreeable to the taste, and are sought 
after by many species of birds, amongst which the Red-headed Woodpecker 
is very conspicuous. 
Young Male. 
Bill of ordinary length, nearly straight, subulato-conical, acute, nearly as 
deep as broad at the base, the edges acute, the gap-line slightly deflected at 
the base. Nostrils basal, lateral, elliptical, half closed by a membrane. Head 
rather small. Neck short. Body slender. Feet of ordinary length, slen- 
der ; tarsus longer than the middle toe, covered anteriorly by a few scut'ella, 
acutely-edged behind ; toes scutellate above, the inner free, the hind toe of 
moderate size ; claws slender, compressed, acute, arched. 
Plumage soft, blended, tufty. Wings of ordinary length, acute, the 
second quill longest. Tail short, notched.
