linensis._

Range.--Alleghanies in Virginia, the Carolinas and Georgia.

A slightly larger bird than the Slate-colored Junco and with the bill
horn color instead of pinkish white. They have been found to breed very
abundantly in the higher ranges of the Carolinas, nesting under banks,
in tufts of grass, or occasionally in small bushes, in fact in such
locations as are used by hyemalis. Their eggs which are laid during May,
June or July (probably two broods being raised) are similar to those of
the Slate-colored species but slightly larger.

567f. MONTANA JUNCO. _Junco hyemalis montanus._

Range.--From northern Idaho and Montana north to Alberta; winters south
to Mexico.

This variety is like _mearnsi_ but darker on the head and throat and
with less pink on the sides. Its nesting habits and eggs do not differ
from those of the Pink-sided Junco.

567g. PINK-SIDED JUNCO. _Junco hyemalis mearnsi._

Range.--Breeds in mountains of Idaho, Wyoming and Montana and winters
south to Mexico.

This species has the head and breast gray, the back brownish and the
sides pinkish brown. They breed at high altitudes in the ranges, placing
their nests of grasses under sods or overhanging rocks; their eggs are
pinkish white before being blown and are spotted over the whole surface
but more heavily at the large end with pale reddish brown and gray. Size
.80 x .60.

570. ARIZONA JUNCO. _Junco phaeonotus palliatus._

Range.--Mountains of western Mexico north to southern Arizona.

Similar to the preceding species but upper mandible blackish and the
gray on throat shading insensibly into the grayish white underparts.
They are quite abundant in the higher ranges of southern Arizona, where
they breed, placing their nests on the ground in similar locations to
those chosen by other Juncos; the three or four eggs are greenish white,
finely speckled chiefly about the large end with reddish brown. Size .76
x .60.

570a. RED-BACKED JUNCO. _Junco phaeonotus dorsalis._

Range.--Breeds in the mountains of New Mexico and Arizona and southward.

This variety is like the last but the reddish brown on the back does not
extend to the coverts or wings. The nesting habits are like those of the
last but the eggs are only minutely specked about the large end.

570b. GRAY-HEADED JUNCO. _Junco phaeonotus caniceps._

Range.--Rocky Mountain region from Wyoming south to Mexico.

This species is similar to the Slate-colored Junco but has a r
