Red crossbills and pine siskins were calling in the larch trees near the house as I left the piazza. The siskins have never been a frequent sight with me in the summer season, and finding almost at once a flock in the grass by the roadside, feeding upon seeds, as well as I could make out, and delightfully fearless, I stopped for a few minutes to look them over. Some of the number showed much more yellow than others, but none of them could have been dressed more strictly in the fashion if their costumes had come straight from Paris. Every bird was in stripes. Both they and the crossbills are what writers upon such themes agree to pronounce “erratic” and “irregular.” Of most birds it can be foretold that they will be in certain places at certain times; their orbits are known; but crossbills and siskins wander through space as the whim takes them. If they have any schedule of times and seasons, men have yet to discover it. When I come to Franconia, for example, I never can tell whether or not I shall find them; a piece of ignorance to be thankful for, like many another. The less knowledge, within limits, the more surprise; and the more surprise--also within limits--the more pleasure. At present I can hardly put my head out of the door without hearing the wheezy calls of siskins and the importunate cackles of crossbills. They are among the commonest and most voluble inhabitants of the valley, and seem even commoner and more talkative than they really are because they are so incessantly on the move. An alder flycatcher is calling as I go up the first hill (he, too, is very common and very free with his voice, although, unlike siskin and crossbill, he knows where he belongs, and is to be found there, and nowhere else), and when I reach the plateau a sapsucker alights near the foot of a telegraph post just before me; a bird in Quakerish drab, with no trace of red upon either crown or throat. He (or she) is only two or three months old, I suppose, like more than half of all the birds now about us. Not far beyond, as the road runs into light woods, with a swampy tract by a brook on the lower side, I hear a chickadee’s voice and look up to see also two Canadian warblers, bits of pure loveliness, the first ones of my present visit. I talk to them, and one, his curiosity responsive to mine, comes near to listen. The Canadian warbler, I have long noticed, has the bump of inquisitiveness exceptionally well developed.
