There is yet another feature of bird music which is characteristic of winter—the singing of passing flocks when high in the air. Day after day, of late, soon after sunrise, a merry company of bluebirds fly over the house, and each one sings as he passes by. Toward sunset they return to the cedar and pine woods across the river, and then, too, they may be heard. Their movements are as regular as those of the crows that roost somewhere in the same neighborhood. I have often failed to see them, they flew at so great an elevation, but their song is not to be confounded with that of any other bird; nor are they like the chats—ventriloquists. Somewhere in the upper regions they were floating along, and their music, drifting earthward, brightens the winter landscape until we think of early spring. But the bluebirds are not always so unsociable. There is a rick of cornstalks not far away, about which I find a pair almost daily, and did not the pestiferous house-sparrows worry them so much, I am sure they would sing more frequently. They appear to realize that their songs may be heard, and so bring down upon them an attack; so, if they warble at all, it is very softly, as though not quite discouraged, and hopeful of better times. They have held their little fort, however, since early autumn, and I am in hopes will outwit their enemies when nesting time arrives. No, it is not true that the country is desolate, even in midwinter. I heard a bluebird sing during the great storm of March, 1888, and since then have been hopeful, although for more than one mile, during my recent outings, comparative silence reigned. And now, what of to-day, the last one of the month? I heard the crested tit whistling in the far-off woods before the sun had risen, and not less musical was the distant cawing of the myriad crows that were just leaving their roost. Overhead, in the tops of the tall pines, were nuthatches and chicadees, and shortly after a host of pine finches. They were all fretting, as I fancied, because the wide reaches of meadow near by were still shut from view, but it was not harsh scolding, after all; and as the day brightened, their voices cleared, until later, when the birds had scattered among the hedges, they all sang sweetly; for at such a time the ear is not critical, and even the plaint of the nuthatch is not out of tune. On and on I walked, expecting in the wilder woods and about the marshy meadows to find birds and birds—many that sang and others that would interest by virtue of their ways. I confidently looked for the host of winter finches and the overstaying herons, but I saw none, heard none. By noon the whole country was sadly silent, and not even a crow passed by. Yet the day was perfect; save a little cooler, it was typical Indian-summer weather. Plant life responded to the inviting sunshine, and I gathered violets and spring beauty. Even the saxifrage shone through the brown leaves, its white buds almost unfolded. It is in vain
