Snow Buntings, or “Brown Snowbirds” as they are called to distinguish them from the juncos, or “Gray Snowbirds,” are not generally known because of the infrequency and irregularity of their visits. They belong to the Sparrow family, but have so much black and white on their wings and tail as to appear very unlike their relatives.

Snowflakes are gentle, fearless little birds, possibly because they come from the sparsely settled regions of the North, where they need not learn to fear human beings. Like chickadees, they appear to love driving storms, and to frolic during February blizzards with as keen delight as warmly clad children; like tree sparrows, they are protected by a layer of fat that keeps out the cold. As they, too, are seed-eaters, snow buntings must journey southward during the winter to regions where deep snows do not bury the weeds.

Few people are aware that in the treeless plains of the north there lives a bird that resembles the much-admired skylark of England in its way of singing. Both snow buntings and skylarks begin to sing as they rise from the ground, sing while on the wing or high up in the air, then drop swiftly to the ground.

Dr. Judd writes as follows about the snowbird: “The snowflake is a bird of the arctic tundra, above the limit of tree growth. In North America it breeds about Hudson Bay, in the northernmost parts of Labrador and Alaska, and to the northward. In its northern home it is a white, black-blotched sparrow, of whose habits very little is known, except that it makes a feather-lined nest on the ground, in which it rears four or five young on a diet which probably consists principally of insects. After the breeding season, however, a buffy brown comes mixed with the black and white, and the birds assume a more sparrowlike aspect. They migrate southward with the first severe cold weather, some of them coming as far south as the northern half of the United States, where their appearance is regarded as a sure sign that winter has begun in earnest. Often a flock of a thousand will come with a blizzard, the thermometer registering 30° to 40° below zero; and in their circling, swirling flight, as they are borne along by the blast, they might well be mistaken at a distance for veritable snowflakes. They settle in the open fields and along railroad tracks, where they secure some food from hayseed, grain that has sifted out of the grain cars, and seeds of weeds that grow along the tracks. Here they remain until April, when, in obedience to the migrating instinct, they journey north to nest on the treeless plains of the arctic regions.

“The snowflake differs from many other winter sparrows, such as the tree sparrow, junco, and white-throated sparrow, in that its flocks act more nearly as units, the alarm of a single member causing the whole flock to whirl up into the air and be off. A further difference may be noted in its strictly terrestrial habits. When not flying, it is almost invariably found on the ground; and when it does happen to alight in a tree, awkward wobblings betray its discomfort. Where the feeding conditions are favorable, immense flocks of snowflakes may be seen apparently rolling like a cloud across the land, this curious effect being due to the rear rank continually rising and flying forward to a point just in advance of the rest of the flock.”[20]

Dr. Judd says that little information can be given concerning the summer food of this bird, but that it probably feeds on the seeds of shore or marsh plants. The winter food consists of grain, mostly gleanings or waste, and of weed seed which is consumed in enormous quantities. “On account of its good work as a weed destroyer and the apparent absence of any noticeably detrimental food habits, the snowflake seems to deserve high commendation, and should receive careful protection.”
