yellowish green ; the outer web of outer feather white instead of a large spot on the inner web. 
The back appears more distinctly streaked. 
The Carbonated Warbler is only known by the description and figure of Mr. Audubon, taken 
from two specimens killed at Henderson, Kentucky, in 1811. The indications are not sufficient 
to show in what particular group of warblers it is to be placed.

Sp. Ch. — Head above chestnut red ; rest of upper parts brownish olive gray ; the feathers with darker centres, the color 
brightening on the rump, upper tail coverts, and outer margins of wing and tail feathers to greenish yellow. A streak from 
nostrils over the eye, and under parts generally, including the tail coverts, bright yellow ; paler on the body. A maxillary 
line ; breast and sides finely but rather obsoletely streaked with reddish brown. Cheeks brownish, (in highest spring plumage, 
chesnut like the head) ; the eyelids and a spot under the eye, olive brown. Lores dusky. A white spot on the inner web of the 
outer two tail feathers at the end. Length, 5 inches ; wing, 2.42: tail, 2.25. 
Hub. — Eastern United States to the Mississippi, and Red river of the North. 
Without a very good series of specimens before me, I am unable to give a complete 
description of the species. None are marked for sex, but skins supposed to be females differ 
chiefly in a less amount of chestnut on the crown. There is no clear indication of any bands 
on the wing, although the edges of the coverts are slightly paler. 
An autumnal male (783) shows a strong tinge of reddish in the olive brown of the back, and 
the chestnut of the crown is much concealed. The under parts are of a very vivid yellow 
throughout, obscured by brown. The axillaries are yellow. As in other specimens, the outer 
web of the first fail feather is whitish on the under surface. In this the tail is nearly even, 
slightly emarginate ; the second and third quills longest ; the first shorter than the fourth. 
The size appears unusually large. Length of skin, 5.20 ; wing, 2.75 ; tail, 2.50. 
In one specimen there is scarcely any yellow about the head and neck, this color being replaced 
by dirty white ; the crown streaked with brown. 
This species in its immature state bears some resemblance to D. tigrina, but is distinguishable 
by the chestnut crown, browner back, less vivid yellow of the rump, much brighter yellow of 
under tail coverts, smaller blotches on the tail feathers, absence of white bands on the wings, &c. 
It is almost certain that the present species is not the Motacilla petechia of Linnaeus, as quoted 
by authors. The diagnosis of Linnaeus, M. olivacea, subtus flava rubro guttata, pileo rubro, 
applies much better to the red crowned variety of D. aestiva than to the present bird. The 
fuller description of Pennant (Arctic Zool. II, 401) says, " crown scarlet, cheeks yellow, hind part 
of neck, back, and rump olive green ; wings and tail dusky, edged with yellow ; beneath rich 
yellow speckled with red, except the vent, which is plain." Vieillot describes Sylvia petechia in 
much the same words, and adds that the tail feathers are brown, margined with yellow, which 
extends furthest in on the inner web. This totally ignores the white terminal spots. The 
S. palmarum is described in detail by Vieillot, and is undoubtedly the present bird.
