Granting the righteousness of the scientist's caution, however, we may still find a less rigorous code sufficient for our own non-scientific, though I hope not unscientific, purpose. For it is certain that no great enjoyment of bird study is possible for some of us, if we are never to be allowed to call our gentle friends by name until in every case we have gone through the formality of a _post-mortem_ examination. Practically, and for every-day ends, we may know a robin, or a redstart, or even a hermit thrush, when we see him, without first turning the bird into a specimen.
Probably there are none of our birds which afford more surprise and pleasure to a novice than the family of warblers. A well-known ornithologist has related how one day he wandered into the forest in an idle mood, and accidentally catching a gleam of bright color overhead, raised his gun and brought the bird to his feet; and how excited and charmed he was with the wondrous beauty of his little trophy. Were there other birds in the woods as lovely as this? He would see for himself. And that was the beginning of what bids fair to prove a life-long enthusiasm.
Thirty-eight warblers are credited to New England; but it would be safe to say that not more than three of them are known to the average New-Englander. How should he know them, indeed? They do not come about the flower-garden like the humming-bird, nor about the lawn like the robin; neither can they be hunted with a dog like the grouse and the woodcock. Hence, for all their gorgeous apparel, they are mainly left to students and collectors. Of our common species the most beautiful are, perhaps, the blue yellow-back, the blue golden-wing, the Blackburnian, the black-and-yellow, the Canada flycatcher, and the redstart; with the yellow-rump, the black-throated green, the prairie warbler, the summer yellow-bird, and the Maryland yellow-throat coming not far behind. But all of them are beautiful, and they possess, besides, the charm of great diversity of plumage and habits; while some of them have the further merit, by no means inconsiderable, of being rare.
It was a bright day for me when the blue golden-winged warbler settled in my neighborhood. On my morning walk I detected a new song, and, following it up, found a new bird,--a result which is far from being a thing of course. The spring migration was at its height, and at first I expected to have the pleasure of my new friend's society for only a day or two; so I made the most of it. But it turned out that he and his companion had come to spend the summer, and before very long I discovered their nest. This was still unfinished when I came upon it; but I knew pretty well whose it was, having several times noticed the birds about the spot, and a few days afterwards the female bravely sat still, while I bent over her, admiring her courage and her handsome dress. I paid my respects to the little mother almost daily, but jealously guarded her secret, sharing it only with a kind-hearted woman, whom I took with me on one of my visits. But, alas! one day I called, only to find the nest empty. Whether the villain who pillaged it traveled on two legs, or on four, I never knew. Possibly he dropped out of the air. But I wished him no good, whoever he was. Next year the birds appeared again, and more than one pair of them; but no nest could I find, though I often looked for it, and, as children say in their games, was sometimes very warm.
