sts are made of slender pieces of twigs,
rootlets and strips of bark, and lined with either hair or feathers, the
eggs are three to five in number, pale greenish white, specked about the
large end with reddish brown and gray. Size .70 x .50. Data.--Raleigh,

663a. SYCAMORE WARBLER. _Dendroica dominica albilora._

Range.--Mississippi Valley, breeding north to Ohio and Illinois, and
west to Kansas and Texas; winters south of the United States.

This bird is precisely like the last except that the superciliary stripe
is usually white. Their nesting habits are precisely like those of the
last, and the nests are usually on horizontal branches of sycamores; the
eggs cannot be distinguished from those of the Yellow-throated Warbler.

664. GRACE'S WARBLER. _Dendroica graciae._

Range.--Southwestern United States, abundant in Arizona and New Mexico.

This Warbler is similar in markings and colors to the Yellow-throated
variety except that the cheeks are gray instead of black. The nesting
habits of the two species are the same, these birds building high in
coniferous trees; the nests are made of rootlets and bark shreds, lined
with hair or feathers; the eggs are white, dotted with reddish brown and
lilac. Size .68 x .48.

665. BLACK-THROATED GRAY WARBLER. _Dendroica nigrescens._

Range.--United States from the Rockies to the Pacific coast and north to
British Columbia; winters south of our borders.

The general color of this species is grayish above and white below as is
a superciliary line and stripe down the side of the throat; the crown,
cheeks and throat are black and there is a yellow spot in front of the
eye. They inhabit woodland and thickets and are common in such
localities from Arizona to Oregon, nesting usually at low elevations in
bushes or shrubs; the nests are made of grasses and fibres, woven
together, and lined with hair or fine grasses, resembling, slightly,
nests of the Yellow Warbler. The eggs are white or greenish white,
specked with reddish brown and umber. Size .65 x .52. Data.--Waldo,
Oregon, June 1, 1901. Nest 3 feet from the ground in a small oak in
