Slowly then I walked up the cañon, looking for my singer. Humming-birds were hovering before the bare rock as before a flower, perhaps sipping the water-drops that here and there trickled down, and large hawks, like mere specks against the blue, were soaring, but no wren could I see. At last I reached the end, with its waterfall fountain. Close within this ceaseless sprinkle, on a narrow ledge that was never dry, was placed--I had almost said grew--a bird's nest; whose, it were needless to ask. One American bird, and one only, chooses perpetual dampness for his environment,--the American dipper, or water ouzel. Here I paused to muse over the spray-soaked cradle on the rock. In this strange place had lived a bird so eccentric that he prefers not only to nest under a continuous shower, through which he must constantly pass, but to spend most of his life in, not on the water. Shall we call him a fool or a philosopher? Is the water a protection, and from what? Has "damp, moist unpleasantness" no terrors for his fine feathers? Where now were the nestlings whose lullaby had been the music of the falling waters? Down that sheer rock, perhaps into the water at its foot, had been the first flight of the ouzel baby. Why had I come too late to see him? But the hours were passing, while I had not seen, and, what was worse, had not heard my first charmer, the cañon wren. Leaving these perplexing conundrums unsolved, I turned slowly back down the walk, to resume my search. Perhaps fifty feet from the ouzel nest, as I lingered to admire the picturesque rapids in the brook, a slight movement drew my attention to a little projection on a stone, not six feet from me, where a small chipmunk sat pertly up, holding in his two hands, and eagerly nibbling--was it, could it be a strawberry in this rocky place?
