Mr. Forbush writes of the junco as follows: “The Snowbird does not often breed in Massachusetts, excepting on the higher lands of the north-central and western parts of the State. Pairs are said to nest occasionally in ice-houses, which are certainly cool, if not suitable situations. It is a bird of the Canadian fauna, and it winters in Massachusetts whenever conditions are favorable. In the southeastern portion of the State, where the ground is bare in sheltered places through much of the winter, or where weed seed, chaff, and other food can be secured, this bird is common in the colder months. Its notes at this season are chiefly sparrow like chirps.
“A flock of these dark birds on the new-fallen snow is an interesting sight on a cold winter’s day, as they come familiarly about the house or barnyard. Audubon says that in winter they burrow in stacks of corn or hay for shelter at night during the continuance of inclement weather. As spring comes they begin to sing much like the Chipping Sparrow. They converse together with a musical twittering, and about the first of May they leave for their northern breeding-ground.”[18]
THE SNOWFLAKE OR SNOW BUNTING
Finch Family—Fringillidæ
Length: A little less than 7 inches; slightly larger than the junco and the English sparrow.
General Appearance: A brown, black, and white bird; the white is conspicuous on wings and tail, especially in flight. The bird has a characteristic way of “hugging the ground” when walking or running—it does not hop.
Male and Female: In winter: head brown on top, lighter on neck; white on sides of head, with a brown thumb-mark below eye; back brown, streaked with black; throat and belly white; a broad brownish band across breast; a brownish wash on sides and rump; wings black and white, some of the feathers edged with brown—in flight, the wings appear white, broadly tipped with black; inner tail-feathers black, outer feathers white. In summer: back and shoulders black, the rest of the body white; wings and tail black and white.
Notes: Thoreau calls their note “a rippling whistle.” He says also, “Besides their rippling note, they have a vibratory twitter, and from the loiterers you hear quite a tender peep.”[19]
Habitat: The tundras of North America. Snow buntings breed in the treeless regions of the North; they migrate southward during the winter.
Range: Northern Hemisphere. In North America, they breed from 83° north (including Greenland), to the northern part of Canada and Alaska; winter from Unalaska and south-central Canada to northern United States, irregularly to northern California, Colorado, Kansas, southern Indiana and Ohio, and Florida.
SNOWFLAKE
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.
