-THROATED SPARROW. _Zonotrichia albicollis._

Range.--North America east of the Plains and breeding from the northern
tier of states northward; winters from the Middle States southward.

To my mind this is the most beautiful of Sparrows, with its bright and
softly blended plumage and the pure white throat boldly contrasting with
its grayish breast and sides of the head; the lores are adorned with a
bright yellow spot. They are one of the most abundant of Sparrows in the
east during migrations and their musical piping whistle is heard from
hedge and wood. They nest most abundantly north of our borders, laying
their three or four eggs in grass lined hollows in the ground, or more
rarely in nests in bushes. The eggs are white or bluish white, thickly
spotted with several shades of brown. Size .85 x .62. They nest most
often in thickets or on the edge of swamps, in just such places as they
are met with on their migrations.

559. TREE SPARROW. _Spizella monticola monticola._

Range.--North America east of the Plains, breeding north of the United
States to the Arctic coast, east of the Rockies; winters within the
United States.

A larger bird but somewhat resembling the common Chipping Sparrow, but
browner above, with a black spot on the breast and no black on the head.
They are quite hardy birds and winter in many of the northern states
where they may be found in flocks upon the snow, feeding on seeds of
protruding weeds. They breed very abundantly in Labrador and about
Hudson Bay, placing their green nests in hollows on the ground or moss;
their three or four eggs are greenish white, abundantly speckled all
over the surface with reddish brown. Size .80 x .55. Data.--Foothills of
Black Mountains, McKenzie River, Arctic America, June 13, 1899. Nest on
the ground under a tuft of grass on level plain; made of grasses and
moss and lined with feathers.

559a. WESTERN TREE SPARROW. _Spizella monticola ochracea._

Range.--North America west of the Plains, breeding in Alaska and
wintering to Mexico. A paler form of the last, the nesting habits and
eggs of which are the same.

560. CHIPPING SPARROW. _Spizella passerina passerina._

Range.--North America east of the Plains, breeding from the Gulf to the
interior of Canada and Newfoundland.
