thickets. It arrives in Pennsylvania about the middle, or last week, of 
April, and begins to build its nest about the middle of May: this is 
fixed on the ground, among the dried leaves, in the very depth of a 
thicket of briers, sometimes arched over, and a small hole left for en- 
trance; the materials are dry leaves and fine grass, lined with coarse 
hair; the eggs are five, white, or semi-transparent, marked with 
specks of reddish brown. The young leave the nest about the 22d of 
June; and a second brood is often raised in the same season, ' Early 
in September they leave us, returning to the south. 
This pretty. little species is four inches and three quarters long, and 
six inches and a quarter in extent ; back, wings, and tail, green olive, 
which also covers the upper part of the neck, but approaches to cine-: 
reous on the crown; the eyes are inserted in a band of black, which 
passes from the front, on both sides, reaching half way down the neck ; 
this is bounded above by another band of white, deepening into light 
blue; throat, breast, and vent, brilliant yellow; belly, a fainter tinge 
of the same color; inside coverts of the wings, ‘also yellow; tips 
and inner vanes of the wings, dusky brown; tail, cuneiform, dusky, 
edged with olive green; bill, black, straight, slender, of the true 
Motacilla form, though the bird itself was considered as a species of. 
Thrush by Linneus, but very properly removed to the genus Mota- 
cilla by Gmelin; legs, flesh colored; iris of the eye, dark hazel. 
The female wants the black band through the eye, has the bill brown, 
-and the throat of a much paler yellow. This last, I have good reason 
to suspect, has been described by Europeans as a separate speciés; 
and that from Louisiana, referred to in the synonymes, appears evidently 
the same as the former, the chief difference, according to Buffon, be- 
ing in its wedged tail, which is likewise the true form of our own 
species; so that this error corrected will abridge the European 
nomenclature of two species. Many more examples of this kind will 
occur in the course of our descriptions.
