Since coming back to Ohio, I imagine that the eastern robins are better singers than their western relatives. Their voices, to my ear, are clearer and more ringing, less apt to break into a squeak at the top of their register, and there is more variety of expression as well as greater facility in managing the technique. I think this is not all fancy, yet I would not speak with the assurance of the dogmatist.
In the good Jayhawker state the orchard orioles are more abundant than they are in the eastern and northeastern part of the state of Ohio. Indeed, the range of this species is more southerly than that of their congeners, the Baltimore orioles. In their proper latitude no birds, or at least few of them, are more lavish of their melody than the orchard orioles. What a ringing voice the oriole possesses! His song has a saucy note of challenge running through it, and also a human intonation that makes it rarely attractive. All day long the male sings his cheery solos, scarcely pausing for breath or food, now sitting on the topmost twig of a dead apple tree in the orchard, now amid the screening foliage of a maple in the yard, and anon on the other side of the street in a stately cottonwood. But where is that modest little personage, his wife? She is seldom heard, and almost as seldom seen. It is really remarkable—her gift of concealment. When she builds her nest is a mystery. It is often so deftly hidden that you would not be likely to find it in a long hunt. In the spring of 1898 a pair of orchard orioles took up their residence in the trees about my house, the male singing his brisk overtures, the female seen only at flitting intervals and never heard. Watch as I would, I could not surprise her laying the timbers of her cottage, which I felt sure was being built somewhere in the trees. Indeed, I did not discover it until autumn came, long after the orioles, old and young, had taken flight to a balmier clime, and the trees were stripped of their leaves, when, lo! it appeared in plain view on one of the trees on the opposite side of the street, the very place where I had not thought of looking for it.
The Baltimore orioles as a rule are not so secretive; yet during the summer of 1898 a pair of these firebirds led me a fruitless chase. Their secret was not divulged until the leaves had fallen the next autumn, when there the nest hung in the midst of a tall cottonwood in my back yard close to the house. Lord Baltimore and his mate usually suspend their nests on the outer branches of the trees, where they are not hard to discover, but this pair did not follow the common formula, for the nest was placed in the thickest part of the foliage, so that it was impossible to see it from the ground until the branches were bare.
Of all the malaperts of birddom none excel and few equal the white-eyed vireo for volubility and downright audacity. All his songs—and he has quite a respectable list of them—seem to be either a protest or a challenge; a protest against your intrusion into his precincts, a challenge to find him and his nest if you can. Again and again in Kansas I crept into their bushy coverts just for the purpose of receiving a sound scolding. Such a berating did they give me, telling me of all my faults and foibles, that I certainly ought to remain humble all the rest of my days. A half dozen viragoes could not have done better—that is, worse. They would flit about in the bushes above my head, their little white eyes gleaming with fire, and call me all the names they could lay their tongues to. I wonder whether the white-eyes have a dictionary of epithets. Nature has done an odd thing in making the white-eyed vireo.
Their nests are not easy to find, although they do not always make a great deal of effort at concealment. Like all the vireo tribe, they suspend their tiny baskets from the fork or crotch of a horizontal twig. The nest is somewhat bulkier than the compact little cup of the red-eyed vireo, and is apt to be more carefully concealed in the foliage, although I have found more than one nest that was hung in plain sight. I remember one in particular. It was dangling from the outer twigs of a small bush by the side of the woodland path which I was pursuing. In fact, it could be distinctly seen from the path. In spite of the mother's pleadings, protests, and objurgations, I stepped over to inspect her pendant domicile, whose holdings were four baby white-eyes, their eyelids still glued together. As the twigs stirred, they opened their mouths for food, and I decided to accommodate them. Taking a bit of cracker from my haversack, I moistened it, and rolled it into a pellet between my finger and thumb; then, gently swaying the bushes, I induced the bantlings to open their mouths, when I dropped the morsel into one of the tiny throats. You ought to have seen the wry face baby made as it gulped down the new kind of food, which had such an odd taste. It was plain that the callow nestling was able to distinguish this morsel from the palatable diet it had been accustomed to. Possibly it suffered from a temporary fit of indigestion, but no permanent harm was done by my experiment, for when I called on them again a few days later, the birdkins four were safe and well, their eyes open, and their instincts sufficiently developed to cause them to cuddle low in their basket instead of opening their mouths.
The rambler who would hear a real outdoor concert should rise early, swallow a few bits of cracker and a cup of coffee, and seek some bird-haunted hollow or woodland just as day begins to break. One morning I pursued this plan, and was more than compensated for the loss of an hour or two of sleep. Just as the east began to blush I found myself in a favorite wooded hollow.
What a potpourri of bird song greeted my ear! How many choralists took part in the matutinal concert I cannot say, but there were scores of them. The volume of song would sometimes swell to a full-toned orchestra, and then for a few moments it would sink almost to a lull, all of it like the flow and ebb of the tides of a sea of melody. It was interesting to note how several voices would sometimes run into a chime when they struck the same chord.
Let me call the roll of the members of that feathered choir. First, and most gifted of all, were a couple of brown thrashers, whose tones were as strong and sweet as those of a silver cornet, making the echoes ring across the hollow. I have listened to many a thrasher song in the North, the South, and the West, but have never heard a voice of better timbre than that of one of the tawny vocalists singing that morning, as he sat on the topmost twig of an oak tree and flung out his medley upon the morning air. It is wonderful, anyway, with what an ecstasy the thrasher will sometimes sing. Nothing could be plainer than that he sings for the pure pleasure of it—an artist deeply in love with his art.
