A little later a scattering flock of tree sparrows were skipping about on the snowy floor of the woods, picking up at quick intervals a palatable tidbit. Birds often find edibles on the surface of the snow when our duller eyes can see nothing but immaculate whiteness. What long leaps the little birds took across the snow, which looked like a marble pavement with fairies dancing upon it! Near by, on one of the lower twigs of a thorn bush, a sparrow sat with feathers fluffed up and wings hanging negligently at his side, as if he were taking a siesta after a hearty meal of weed seeds and winter berries. Two of his companions soon joined him in his noonday rest, the trio making a pretty picture sitting there within an inch or two of the ground. It was not very long before a tree sparrow perpetrated another surprise, proving that this species is not without character, as indeed no species is. He leaped to the bole of a sapling, clinging there a few moments like a chickadee or a wren, while he pecked an appetizing morsel from the bark; then he dropped down to the snow for a brief breathing spell, after which he sprang up again to the sapling for a few more bits, repeating the little performance a number of times. In the same part of the woods a company of chickadees was flitting about in the trees, plunging into the little snowbanks on the twigs, sometimes standing in them up to their white bosoms, and often brushing a segment to the ground, thus making numerous breaches in the white drifts. The racket they made with their scolding and piping might have been called a musical din. Deciding to watch them a while, I flung myself down upon the snow. This act was the signal for a precious to-do among the nervous little potherers. Did any one ever hear or read of such a performance in all the annals of birdland? What in the world did it mean--a man lying flat on the ground out there in the woods? I was highly amused at the hurly-burly, and decided to add still more variety to it. Suddenly I sprang to my feet with a shout. Several of the birds dropped, as if shot, into a thorn bush below them, where they set up a hubbub that would have made on old-time Puritan laugh, even at the risk of being censured for levity. By and by they quieted down, and one of them began to whistle his pretty minor tune with as much serenity as if he had never been excited in his life. My winter outing proved that the Frost King and the hardy birds often go cheek by jowl, as if they were on terms of the most cordial fraternity. ODDS AND ENDS The ornithologist is always interested in noting how the conduct of birds of the same species differs and agrees in different localities. In a previous chapter some of the differences between the avifauna of Ohio and Kansas have been described, but a good deal still remains to be said, teaching more than one lesson in comparative ornithology.
