SPECIES 27 . SYLVM RJiRJi. 
BLUE-GREEN WARBLER. 
[Plate XXVII.— Fig. 2.] 
Pkale’s Museum, JVo. 7788 . 
This new species, the only one of its sort I have yet met 
with, was shot on the banks of Cumberland river, about the be- 
ginning of April; and the drawing made with care immediately 
after. Whether male or female I am uncertain. It is one of 
those birds that usually glean among the high branches of the 
tallest trees, which render it difficult to be procured. It was 
darting about with great nimbleness among the leaves, and ap- 
peared to have many of the habits of the Flycatcher. After 
several ineffectual excursions in search of another of the same 
kind, with which I might compare the present, I am obliged 
to introduce it with this brief account. 
The specimen has been deposited in Mr. Peale’s museum. 
The Blue-green Warbler is four inches and a half long, and 
seven and a half in extent; the upper parts are verditer, tinged 
with pale green, brightest on the front and forehead; lores, line 
over the eye, throat, and whole lower parts very pale cream; 
cheeks slightly tinged with greenish; bill and legs bright light 
blue, except the upper mandible, which is dusky; tail forked, 
and, as well as the wings brownish black; the former marked 
on the three exterior vanes with white and edged with greenish; 
the latter having the first and second row of coverts tipt with 
white. Note a feeble chirp.
