Now straight before me, up a woody aisle, an olive-backed thrush stands in full view and a perfect light, facing me and singing, a lovely chorister. Looking at him, I catch a flutter of yellow and black among the leaves by the streamlet; a Kentucky warbler, I suspect, but I dare not go forward to see, for now the thrushes are in chorus again. By and by he comes up from his bath, and falls to dressing his feathers: not a Kentucky, after all, but a Canadian flycatcher, my first one here. He, too, is an exquisite, with fine colors finely laid on, and a most becoming jet necklace. While I am admiring him, a blue yellow-back begins to practice his scales--still a little blurred, and needing practice, a critic might say--somewhere at my right among the hillside oaks; another exquisite, a beauty among beauties. I see him, though he is out of sight. And what seems odd, at this very moment his rival as a singer of the scale, the prairie warbler, breaks out on the other side of me. Like the chat and the indigo-bird, he is abundantly at home hereabout. All this woodland music is set off by spaces of silence, sweeter almost than the music itself. Here is peace unbroken; here is a delicious coolness, while the sun blazes upon the dusty road above me. How amiable a power is contrast--on its softer side! I think of the eager, bloody, sweaty, raging men, who once stormed up these slopes, killing and being killed. The birds know nothing of all that. It might have been thousands of years ago. The very trees have forgotten it. Two or three cows come feeding down the glade, with the lazy tinkle of a bell. And now my new friend, the blue-winged yellow warbler, sings across the path (across the aisle, I was going to say), but only two or three times, and with only two insignificant lisping syllables. The chary soul! He sings to the eye, I suppose. I go over to look at him, and my sudden movement startles the thrushes, who, finding themselves again in the singers' gallery, cannot refrain from another chorus. At the same moment the Canadian warbler comes into sight again, this time in a tupelo. The blue-wings are found without difficulty; they have a call like the black-and-white creeper's. A single rough-winged swallow skims above the treetops. I have seen him here before, and one or two others like him.
