amiss by even the most fastidious taxpayer. He replied that it would be of no use; we hadn't any birds now, and we shouldn't have any so long as the English sparrows were here to drive them away. But it would be of use, notwithstanding; and certainly it would afford a pleasure to many people to see flocks of goldfinches, red-poll linnets, tree sparrows, and possibly of the beautiful snow buntings, feeding in the Garden in midwinter.

Even as things are, however, the cold season is sure to bring us a few butcher-birds. These come on business, and are now welcomed as public benefactors, though formerly our sparrow-loving municipal authorities thought it their duty to shoot them. They travel singly, as a rule, and sometimes the same bird will be here for several weeks together. Then you will have no trouble about finding here and there in the hawthorn trees pleasing evidences of his activity and address. Collurio is brought up to be in love with his work. In his Mother Goose it is written,—

and however long he may live, he never forgets his early training. His days, as the poet says, are "bound each to each by natural piety." Happy lot! wherein duty and conscience go ever hand in hand; for whose possessor

In appearance the shrike resembles the mocking-bird. Indeed, a policeman whom I found staring at one would have it that he was a mocking-bird. "Don't you see he is? And he's been singing, too." I had nothing to say against the singing, since the shrike will often twitter by the half hour in the very coldest weather. But further discussion concerning the bird's identity was soon rendered needless; for, while we were talking, along came a sparrow, and dropped carelessly into a hawthorn bush, right under the shrike's perch. The latter was all attention instantly, and, after waiting till the sparrow had moved a little out of the thick of the branches, down he pounced. He missed his aim, or the sparrow was too quick for him, and although he made a second swoop, and followed that by a hot chase, he speedily came back without his prey. This little exertion, however, seemed to have provoked his appetite; for, instead of resuming his coffee-tree perch, he went into the hawthorn, and began to feed upon the carcass of a bird which, it seemed, he had previously laid up in store. He was soon frightened off for a few moments by the approach of a third man, and the policeman improved the opportunity to visit the bush and bring away his breakfast. When the fellow returned and found his table empty, he did not manifest the slightest disappointment (the shrike never does; he is a fatalist, I think); but in order to see what he would do, the policeman tossed the body to him. It lodged on one of the outer twigs, and immediately the shrike came for it; at the same time spreading his beautifully bordered tail and screaming loudly. Whether these demonstrations were intended to express delight, or anger, or contempt, I could not judge; but he seized the body, carried it back to its old place, drove it again upon the thorn, and proceeded to devour it more voraciously than ever, scattering the feathers about in a lively way as he tore it to pieces. The third man, who had never before seen such a thing, stepped up within reach of the bush, and eyed the performance at his leisure, the shrike not deigning to mind him in the least. A few mornings later the same bird gave me another and more amusing exhibition of his nonchalance. He was singing from the top of our one small larch-tree, and I had stopped near the bridge to look and listen, when a milkman entered at the Commonwealth Avenue gate, both hands full of cans, and, without noticing the shrike, walked straight under the tree. Just then, however, he heard the notes overhead, and, looking up, saw the bird. As if not knowing what to make of the creature's assurance, he stared at him for a moment, and then, putting down his load, he seized the trunk with both hands, and gave it a good shake. But the bird only took a fresh hold; and when the man let go, and stepped back to look up, there he sat, to all appearance as unconcerned as if nothing had happened. Not to be so easily beaten, the man grasped the trunk again, and shook it harder than before; and this time Collurio seemed to think the joke had been carried far enough, for he took wing, and flew to another part of the Garden. The bravado of the butcher-bird is great, but it is not unlimited. I saw him, one day, shuffling along a branch in a very nervous, unshrikely fashion, and was at a loss to account for his unusual demeanor till I caught sight of a low-flying hawk sweeping over the tree. Every creature, no matter how brave, has some other creature to be afraid of; otherwise, how would the world get on?

The advent of spring is usually announced during the first week of March, sometimes by the robins, sometimes by the bluebirds. The latter, it should be remarked, are an exception to the rule that our spring and autumn callers arrive and depart in the night. My impression is that their migrations are ordinarily accomplished by daylight. At all events I have often seen them enter the Common, alight for a few minutes, and then start off again; while I have never known them to settle down for a visit of two or three days, in the manner of most other species. This last peculiarity may be owing to the fact that the European sparrows treat them with even more than their customary measure of incivility, till the poor wayfarers have literally no rest for the soles of their feet. They breed by choice in just such miniature meeting-houses as our city fathers have provided so plentifully for their foreign protégés; and probably the latter, being aware of this, feel it necessary to discourage at the outset any idea which these blue-coated American interlopers may have begun to entertain of settling in Boston for the summer.

The robins may be said to be abundant with us for more than half the year; but they are especially numerous for a month or two early in the season. I have counted more than thirty feeding at once in the lower half of the parade ground, and at nightfall have seen forty at roost in one tree, with half as many more in the tree adjoining. They grow extremely noisy about sunset, filling the air with songs, cackles, and screams, till even the most stolid citizen pauses a moment to look up at the authors of so much clamor.

By the middle of March the song sparrows begin to appear, and for a month after this they furnish delightful music daily. I have heard them caroling with all cheerfulness in the midst of a driving snow-storm. The dear little optimists! They never doubt that the sun is on their side. Of necessity they go elsewhere to find nests for themselves, where they may lay their young; for they build on the ground, and a lawn which is mowed every two or three days would be quite out of the question.

At the best, a public park is not a favorable spot in which to study bird music. Species that spend the summer here, like the robin, the warbling vireo, the red-eyed vireo, the chipper, the goldfinch, and the Baltimore oriole, of course sing freely; but the much larger number which merely drop in upon us by the way are busy feeding during their brief sojourn, and besides are kept in a state of greater or less excitement by the frequent approach of passers-by. Nevertheless, I once heard a bobolink
