No ear tufts. Plumage white, more or less heavily spotted with black, the female usually being quite strongly barred on the back. They are locally abundant in the far north, preferring low, mossy lands to the more timbered districts. Here they find an abundance of food during the summer months, living upon hares, lemmings, ptarmigan and ducks. They are about the equal of the [Horned Owl] in strength, and usually will weigh a few ounces more; they will frequently kill animals or birds as heavy, or heavier, than themselves. They also catch a great many fish; these they get in shallow water among the rock-weed covered stones, by reaching down quickly and seizing their prey in their strong claws.

Nest.—On the ground in dry portions of marshes; the 2 to 8 eggs are pure white.

Range.—Breeds from Labrador and Hudson Bay, northward, and possibly farther south; winters casually to the Middle States, and commonly to Minnesota and Maine.

AMERICAN HAWK OWL

377a. Surnia ulula caparoch. 15 in.

Tail long and rounded; plumage mottled black, white and gray, with little, if any, brownish tinge; heavily barred with black. These owls, curiously resembling a hawk in build, and more so in flight, are very active and hunt more during the daytime than after dark. They feed largely upon small rodents and lemmings which are very abundant in their summer home, and also kill a great many small birds. They seem to be impartial to wooded districts, or open marshes and low lands, where they may be seen skimming about close to the ground.

Nest.—Either of sticks in the tops of trees, or in hollow cavities. The eggs are white, as are those of all owls, and nearly globular in shape (1.40 × 1.25).

Range.—Breeds from Newfoundland and Manitoba northward, and possibly farther south on the mountains. Winters south to northern United States, rarely to New York and Illinois.
