On the 18th I found a single olive-backed thrush, silent, in company with a flock of robins, or in the same grove with them--a White Mountain bird, thrice welcome; and this morning a few white-throated sparrows appeared. The first one that I saw--the only one, in fact--was a young fellow, and as I caught sight of him facing me, with his clear white throat, and his breast prettily streaked, with a wash of color across it, I was half in doubt what to call him. While I was taking observations upon his plumage, trying to make him look like himself, he began to _chip_, as if to help me out, and a second one unseen fell to singing near by; a very feeble and imperfect rendering of the dear old tune, but well marked by the “Peabody” triplets. It was a true touch of autumn, a voice from the hills. Shortly before this I had spent a long time in watching the actions of a Lincoln finch. He was feeding upon Roman worm-wood seeds by the roadside, in company with two or three chipping sparrows; very meek and quiet in his demeanor, and happily not disposed to resent my inquisitiveness, which I took pains to render as little offensive as possible. I had not seen the like of him since May, and have seen so few of his race at any time that every new one still makes for me an hour of agreeable excitement. In the same neighborhood an indigo-bird surprised me with a song. He was as badly out of voice as the white-throat, but his spirit was good, and he sang several times over. One would never have expected music from him, to look at his plumage. The indigo color was largely moulted away--only the rags of it left. It was really pitiful to see him; so handsome a coat, now nothing but shreds and patches. Most likely he was not a traveler from farther north, but a lingering summer resident of our own, as I remember to have seen three birds of his name in the same spot fifteen days ago. It would be interesting to know whether bright creatures of this kind do not feel humiliated and generally unhappy when they find their beauty dropping away from them, like leaves from the branch, as the summer wanes.
