Turs is another spring passenger through the United States to the 
north. This bird, as well as Fig. 67, from the particular form of its bill, 
ought rather to be separated from the Warblers ; or, along with several 
others of the same kind, might be arranged as a ‘sub-genera, or partic- 
ular family of that tribe, whjch might with propriety be called Worm- 
eaters, the Motacilla vermivora of ‘Turton having the bill exactly of ° 
this form. The habits of these birds partake a good deal of those of 
the Titmouse ; and, in'their language and action, they very much fe- 
semble them. All that can be said of this species is, that it appears 
in Pennsylvania for a few: days, about the last of April or beginning 
of May, darting actively among the young leaves and opening buds, 
and is rather a scarce species. 
The Golden-winged Warbler is five inches long, and seven broad ; 
the crown, golden yellow’ the first and second row of wing-coverts, 
of the same rich yellow; the rest of the upper parts, a deep ash, or 
dark slate color ; tail, slightly forked, and, as well as the wings, edged. 
with whitish; a "black band passes through the eyé, and is separated 
from. the yellow of the crown, by a fine line of white; chin and throat, 
black, between which and that passing through the eye runs a strip 
of white, as in the. figure; belly and vent, white ; bill, black, gradually 
tapering to a sharp point ; legs, dark ash ; irides, hazel. 
Pennant has described this species twice, first, as ‘the Golden- 
winged Warbler, and, immediately after, as the Yellow-fronted 
Warbler. See the synonymes at the beginning of this article.

I Know little of this bird. It is one of those transient visitors that, 
in the month of April, pass through Pennsylvania, on its way to the
