But the chief singers were the olive-backed thrushes and the winter wrens. I should be glad to know on just what principle the olive-backs and their near relatives, the hermits, distribute themselves throughout the mountain region. Each species seems to have its own sections, to which it returns year after year, and the olive-backed, being, as is well known, the more northern species of the two, naturally prefers the more elevated situations. I have found the latter abundant near the Profile House, and for three seasons it has had exclusive possession of the White Mountain Notch,--so far, at least, as I have been able to discover.[9] The hermits, on the other hand, frequent such places as North Conway, Gorham, Jefferson, Bethlehem, and the vicinity of the Flume. Only once have I found the two species in the same neighborhood. That was near the Breezy Point House, on the side of Mount Moosilauke; but this place is so peculiarly romantic, with its noble amphitheatre of hills, that I could not wonder neither species was willing to yield the ground entirely to the other; and even here it was to be noticed that the hermits were in or near the sugar-grove, while the Swainsons were in the forest, far off in an opposite direction.[10]
It is these birds, if any, whose music reaches the ears of the ordinary mountain tourist. Every man who is known among his acquaintances to have a little knowledge of such things is approached now and then with the question, "What bird was it, Mr. So-and-So, that I heard singing up in the mountains? I didn't see him; he was always ever so far off; but his voice was wonderful, so sweet and clear and loud!" As a rule it may safely be taken for granted that such interrogatories refer either to the Swainson thrush or to the hermit. The inquirer is very likely disposed to be incredulous when he is told that there are birds in his own woods whose voice is so like that of his admired New Hampshire songster that, if he were to hear the two together, he would not at first be able to tell the one from the other. He has never heard them, he protests; which is true enough, for he never goes into the woods of his own town, or, if by chance he does, he leaves his ears behind him in the shop. His case is not peculiar. Men and women gaze enraptured at New Hampshire sunsets. How glorious they are, to be sure! What a pity the sun does not sometimes set in Massachusetts!
