eaves, bark and grass, lined with
hair; the four or five eggs are white, specked with reddish brown and
neutral tints; size .70 x .50. Data.--Doddridge Co., Mo., May 29, 1897.
Nest one foot from the ground in a small bush; made of leaves, strips of
bark and fine grasses.

685. WILSON'S WARBLER. _Wilsonia pusilla pusilla_.

Range.--Eastern North America, breeding from northern United States
northward; south to Central America in winter.

These handsome little black-capped flycatching Warblers are abundant
during migrations, especially in the spring, being found on the edges of
woods and in orchards. They nest on the ground, usually on the edges of
swamps, embedding their nests in the ground under the shelter of low
branches or on the edges of banks; the nest is of bark strips, fibres
and leaves, and the eggs are white, specked with reddish brown; size .60
x .50.

685a. PILEOLATED WARBLER. _Wilsonia pusilla pileolata._

Range.--Western United States, breeding in the Rocky Mountain region
from Mexico to Alaska; winters south of the United States.

Similar to the eastern form but the yellow underparts and greenish back
are brighter. Like the last species, this form nests on the ground or
very close to it, in weeds or rank undergrowth, in swamps. Their eggs
which are laid in May or June are not distinguishable from those of the
last.

685b. GOLDEN PILEOLATED WARBLER. _Wilsonia pusilla chryseola._

Range.--Pacific coast of North America, breeding from southern
California in mountain ranges north to British Columbia.

686. CANADIAN WARBLER. _Wilsonia canadensis._

Range.--Eastern North America, breeding from Mass., New York, and
Michigan north to Labrador and Hudson Bay; winters in Central America.

This handsome Warbler is plain gray above and yellow below, with a black
stripe down the sides of the neck and across the breast in a broken
band. They frequent swamps or open woods with a heavy growth of
underbrush, where

they build their nests on or very close to the ground. I have always
found them in Massachusetts nesting about the roots of laurels, the
nests being made of strips of bark, leaves and grass; in June or the
latter part of May they lay from three to five white eggs, specked and
wreathed with reddish brown and neutral tints
