A few birds, too familiar to have attracted any particular notice on their own account, became interesting because of the fact that they were not included among those found here by Mr. Brewster. One of these was the Maryland yellow-throat, of which Mr. Brewster saw no signs above a level of 2100 feet. (The elevation of Highlands, I may remind the reader, is 3800 feet.) At the time of my visit, the song, _witchery, witchery, witchery_, or _fidgety, fidgety, fidgety_ (every listener will transliterate the dactyls for himself), was to be heard daily from the hotel piazza, though so far away that, with Mr. Brewster’s negative experience in mind, I deferred listing the name till, after two or three days, I found leisure to go down to the swamp out of which the notes, whatever they were, evidently proceeded. Then it transpired that at least five males were in song, in four different places. And later (May 25) I happened upon one in still another and more distant spot. Probably the species had come in since Mr. Brewster’s day (eleven years before), with some change of local conditions,--the cutting down of a piece of forest, perhaps, and the formation of a bushy swamp in its place. A villager closely observant of such things, and well acquainted with the bird, assured me from his own recollection of the matter (and he remembered Mr. Brewster’s visit well) that such was pretty certainly the case. Another bird seen almost daily, though in limited numbers, was the red-winged blackbird, which Mr. Brewster noticed only in a few places in the lower valleys. It seemed well within the range of probability that the same changes which had brought in one lover of sedgy tussocks and button-bushes should have attracted also another. I made no search for nests, but the fact that the birds were seen constantly from May 7 to May 27 may be taken as reasonably conclusive evidence that they were on their breeding-grounds. Two or more pairs of phœbes had settled in the neighborhood, and two or more pairs of parula warblers. The former were not found by Mr. Brewster above a level of 3000 feet, and the latter he missed at Highlands, although, as he says, the presence of trees hung with usnea lichens made their absence a surprise.
