533. PINE SISKIN. _Spinus pinus._

Range.--Breeds from northern United States northward, in the Alleghanies
and in the Rockies south to New Mexico. Winters throughout the United
States.

Siskins are of the size of the Goldfinch (5 inches long), and their
calls, songs and habits are similar to those of this bird. Their plumage
is grayish brown, streaked with dusky and the bases of the wings and
tail feathers are yellow. Like the Crossbills, they frequently feed
along our northern borders, but very sporadically. Their nests are built
on horizontal branches of pines or cedars at any elevation from the
ground, being made of grasses and rootlets lined with hair or pine
needles, and of rather frail and flat construction. Their eggs are laid
during May or June and are greenish white, specked with reddish brown;
size .68 x .48. Data.--Hamilton Inlet, Labrador, June 17, 1898. Nest on
branch of a spruce, 10 feet from the ground; made of grass, lined with
moss and feathers. Collector, L. Dicks.

534. Snow Bunting. _Plectrophenax nivalis nivalis._

Range.--Breeds in the Arctic regions, and winters irregularly in large
flocks through the United States to Oregon, Kansas and Georgia.

These birds are only seen in the United States in large roving flocks,
during the winter when they feed on weed seeds on side hills. Their
nests are built on the ground, being sunk into the sphagnum moss, and
made of grasses lined with feathers. Their four or five eggs are a light
greenish white, spotted and splashed with yellowish brown and lilac.
Size .90 x .65.

Range.--Pribilof and Aleutian Islands, Alaska.

A slightly larger variety which is resident on the islands in its range.
