I have said nothing about it hitherto, but I had not driven five or six hours through strange woods and into the midst of strange hills without an ear open for bird notes. Even the rumbling of the heavy wagon and the uneasy creaking of the harness could not drown such music altogether, and once in a while, as I have said, I spelled myself on foot. At short intervals, too, when we came to some promising spot,--a swampy thicket, perhaps, or a patch of evergreens,--I called a halt to listen; the driver making no objection, and the horses less than none. The voices, to my regret rather than to my surprise, were every one familiar, and the single unexpected thing about it all was the dearth of northern species. The date was May 6, and the woods might properly enough have been alive with homeward-bound migrants; but the only bird that I could positively rank under that head was a Swainson thrush,--a free-hearted singer, whose cheery White Mountain tune I never hear at the South without an inward refreshment. From the evergreens, none too common, and mostly too far from the road, came the voices of a pine warbler and one or two black-throated greens; and once, as we skirted a bushy hillside, I caught the sliding ditty of a prairie warbler. Here, too, I think it was that I heard the distinctive, loquacious call of a summer tanager,--four happy chances, as but for them, and the single gnatcatcher by the half-way house gate, my vacation bird list would have been shorter by five species. After all, the principal ornithological event of the forenoon was, not the singing of the Swainson thrush, but the discovery of a humming-bird’s nest. This happened on the side of Stumphouse Mountain. I had taken a short cut by myself, and had come out of the woods into the road again some distance ahead of the wagon, when suddenly I heard the buzz and squeak of a hummer, and, glancing upward, put my eye instantly upon the nest, which might have been two thirds done from its appearance, and then upon its owner, whose reiterated squeakings, I have no doubt, expressed her annoyance at my intrusion. In truth, both owners were present, and in that lay the exceptional interest of the story.
