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 × 1.75. [Illustration 021: Pacific Loon.

Family ALCIDÆ 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. They stand upright on the sole of the foot and are able to walk quite easily on land. Puffins have very heavy and deep but thin bills, which are entirely unlike those of any other bird and often give then the name of Parrot Auks. Puffins, Auks and Murres are otherwise recognized by the presence of but three toes which are webbed.

TUFTED PUFFIN. _Lunda cirrhata._ Range.--Pacific Coast from Alaska southward to southern California, breeding locally throughout their range. Tufted Puffins are the largest of the Puffins. In the breeding plumage, they are a sooty brownish or black color; the cheeks are white, and a long tuft of straw colored feathers extends back from each eye; the bill is bright red and greenish yellow. They breed commonly on the Farallones, where two or three broods are raised by a bird in a single season, but much more abundantly on the islands in the north. Their single eggs are laid in burrows in the ground or else in natural crevices formed by the rocks. The eggs are pure white or pale buff and are without gloss. They very often have barely perceptible shell markings of dull purplish color. The eggs are laid about the middle of June. Size 2.80 × 1.90. Data.--Farallone Is., May 27, 1887. Single egg laid in crevice of rocks. Collector, W. O. Emerson.
