the neck. Its size, too, is about five
inches shorter. The nesting habits are the same as the Loons and the
eggs have rather more of an olive tint besides having the majority of
spots at the larger end. Size 3.10 x 2.00.

10. PACIFIC LOON. _Gavia pacifica._

Range.--Western North America along the coast chiefly, breeding from
Alaska south to British Columbia. In winter, south along the coast to
Mexico.

This species differs from the Black-throated only in the tint of the
head reflections. The habits are the same as those of the other members
of the family. They lay two eggs of a greenish brown or greenish gray
hue with black spots. Size 3.10 x 1.90. Data.--Yukon River, Alaska, June
28, 1902. Nest of rubbish on an island; found by a miner.

11. RED-THROATED LOON. _Gavia stellata._

Range.--Northern parts of North America, breeding from southern Canada
northward in the interior on both coasts. South to the middle portions
of the United States in winter.

This is the smallest of the Loon family, being twenty-five inches in
length. In plumage it is wholly unlike any of the other members at all
seasons of the year. In summer the back, head and neck are gray, the
latter being striped with white. A large chestnut patch adorns the front
of the lower part of the neck. In winter the back is spotted with white,
whereas all the others are unspotted at this period. The nesting habits
are identical with the other species; the ground color of the two eggs
is also the same. Size 2.00 x 1.75.

PUFFINS, AUKS and MURRES.
Family ALCIDAE

Puffins, Auks and Murres are all sea birds and are only found inland
when blown there by some severe storm of winter. At this season numbers
of them are apt to lose their bearings and may sometimes be found with
their feet frozen in some of our inland ponds. Puffins are heavily built
birds in appearance, but are very active both on the wing and in the
water. Their wings are much larger comparatively than those of the other
members of this family, so they are enabled to perform evolutions in the
air, which are withheld from the others.
