Our winter sparrows are easy to identify. The song sparrow may, of course, be known by the streaks of black and brown upon his breast and sides, and by the blotch which these form in the centre of the breast. The tree sparrow, which comes to us from Hudson Bay and Labrador, lacks the stripes, but has the centre spot. This is one of our commonest field birds in winter, notwithstanding his name. The most omnipresent and abundant of all our winter visitors from the north are the juncos, or snowbirds. Slate coloured above and white below, perfectly describes these birds, although their distinguishing mark, visible a long way off, is the white V in their tails, formed by several white outer feathers on each side. The sharp chirps of juncos are heard before the ice begins to form, and they stay with us all winter. We have called the junco a snowbird, but this name should really be confined to a black and white bunting which comes south only with a mid-winter's rush of snowflakes. Their warm little bodies nestle close to the white crystals, and they seek cheerfully for the seeds which nature has provided for them. Then a thaw comes, and they disappear as silently and mysteriously as if they had melted with the flakes; but doubtless they are far to the northward, hanging on the outskirts of the Arctic storms, and giving way only when every particle of food is frozen tight, the ground covered deep with snow, and the panicled seed clusters locked in crystal frames of ice. The feathers of these Arctic wanderers are perfect non-conductors of heat and of cold, and never a chill reaches their little frames until hunger presses. Then they must find food and quickly, or they die. When these snowflakes first come to us they are tinged with gray and brown, but gradually through the winter their colours become more clear-cut and brilliant, until, when spring comes, they are garbed in contrasting black and white. With all this change, however, they leave never a feather with us, but only the minute brown tips of the feather vanes, which, by wearing away, leave exposed the clean new colours beneath. Thus we find that there are problems innumerable to verify and to solve, even when the tide of the year's life is at its lowest ebb. From out the white and pulsing storm I hear the snowbirds calling; The sheeted winds stalk o'er the hills, And fast the snow is falling. On twinkling wings they eddy past, At home amid the drifting, Or seek the hills and weedy fields Where fast the snow is sifting. Their coats are dappled white and brown Like fields in winter weather, But on the azure sky they float Like snowflakes knit together.
