"It gives one a genuine sense of relief to turn from this Apache, this treacherous scalper of birds, to those genuinely useful little songsters, the tree and the song sparrow. The former is essentially a Northern bird, and breeds in the high arctic regions. He has a fine song, which we hear in early April as his parting souvenir. The song sparrow will be a great favorite with you, Miss Amy, for he is one of our finest singers, whose song resembles the opening notes of a canary, but has more sweetness and expression. Those that remain with us depart for the North at the first tokens of spring, and are replaced by myriads of other migrants that usually arrive early in March. You will hear them some mild morning soon. They are very useful in destroying the worst kinds of insects. A fit associate for the song sparrow is the American goldfinch, or yellow-bird, which is as destructive of the seeds of weeds as the former is of the smaller insect pests. In summer it is of a bright gamboge yellow, with black crown, wings, and tail. At this time he is a little olive-brown bird, and mingles with his fellows in small flocks. They are sometimes killed and sold as reed-birds. They are brilliant singers. "The snow-bird and snow-bunting are not identical by any means; indeed, each is of a different genus. The bunting's true home is in the far North, and it is not apt to be abundant here except in severe weather. Specimens have been found, however, early in November, but more often they appear with a late December snowstorm, their wild notes suggesting the arctic wastes from which they have recently drifted southward. The sleigh tracks on the frozen Hudson are among their favorite haunts, and they are not often abundant in the woods on this side of the river. Flocks can usually be found spending the winter along the railroad on the eastern shore. Here they become very fat, and so begrimed with the dirt and grease on the track that you would never associate them with the snowy North. They ever make, however, a singular and pretty spectacle when flying up between one and the late afternoon sun, for the predominant white in their wings and tail seems almost transparent. They breed at the extreme North, even along the Arctic Sea, in Greenland and Iceland, and are fond of marine localities at all times. It's hard to realize that the little fellows with whom we are now so familiar start within a month for regions above the Arctic Circle. I once, when a boy, fired into a flock feeding in a sleigh track on the ice of the river. Some of those that escaped soon returned to their dead and wounded companions, and in their solicitude would let me come very near, nor, unless driven away, would they leave the injured ones until life was extinct. On another occasion I brought some wounded ones home, and they ate as if starved, and soon became very tame, alighting upon the table at mealtimes with a freedom from ceremony which made it necessary to shut them up.
