232 AUTUMNAL WARBLER 
ety of the Yellow-fronted Warbler, a very different species. The 
specimen sent to Europe, and first described by Pennant, appears also 
to have been a female, as the breast is said to be yellow, instead of 
the brilliant orange with which it is ornamented. Of the nest and 
habits of this bird I can give no account, as there.is not more than one 
or two of these birds tobe found here in a season, even with the most 
diligent search. ; 
The Blackburnian Warbler is four inches and a half long, and sev- 
en in extent; crown, black, divided by a line of orange; the black 
again bounded on the outside by a stripe of rich orange passing over 
the eye; under the eye, a small touch of orange yellow; whole throat 
and breast, rich, fiery orange, bounded by spots and streaks of black; 
belly, dull yellow, also streaked with black; vent, white ; back, black, 
skirted with ash; wings, the same, marked with a large lateral spot of 
white ; tail, slightly forked; the interior vanes of the three exterior 
feathers, white; cheeks, black; bill and legs, brown. The female is 
yellow where the male is orange; the black streaks are also more 
obscure and less numerous.

Tus plain, little species regularly visits Pennsylvania from the 
north, in the month of October, gleaning among the willow leaves; 
but, what is singular, is rarely seen in spring. . From the Ist to the 
15th of October, they may be seen. in considerable numbers, almost 
every day, in gardens, particularly among the branches of the weeping- 
willow, and seem exceedingly industrious. They have some resem- 
blance, in color, to the Pine-creeping Warbler; but do not run along 
the trunk like that bird, neither do they give a preference to the pines. 
They are also less. After the first of November, they are no Jonger 
to be found, unless the season be uncommonly mild. These birds, 
doubtless, pass through Pennsylvania in spring, on their way to 
the north; but either make a very hasty journey, or frequent the tops 
of the tallest trees; for I have never yet met with one of them in that 
season, though in October I have seen more than a hundred in an 
afternoon’s excursion. : 
Length, four inches and three quarters; breadth, eight inches; 
whole upper parts, olive green, streaked on the back with dusky 
stripes; tail-coverts, ash, tipped with olive; tail, black, edged with 
dull white ; the three exterior feathers, marked near the tip with white ; 
wings, deep dusky, edged with olive, and crossed with two bars of 
white ; primaries, also tipped, and three secondaries next the body, 
edged with white; upper mandible, dusky brown; lower, as well as 
the chin and. breast, dull yellow; belly and vent, white; legs, dusky 
brown; feet and claws, yellow; a pale, yellow ring surrounds the 
eye. The males of these birds often warble out some low but very 
sweet notes, while searching among the leaves in autumn.
