But why was not the grass-finch, his relative of the fields, in just as good voice when he arrived on the thirty-first? The last two springs this bird had to be on his singing-grounds several days before he recovered his full powers of voice. On the twenty-ninth the phœbe came with his burden of sweet song, and the first of April brought Bewick’s wren—sweet-voiced Arion of the suburbs—and the chipping sparrow, whose slender peal of song rang through my study window. Here my record stops for the present year; but by reference to my last year’s notes (1891) it appears that Bewick’s wren did not then arrive until April tenth, and chippy not until April twelfth. The difference in the seasons is doubtless the primary cause of this divergence in the time of arrival. April brings many other winged pilgrims,—the white-throated and white-crowned sparrows, the thrushes, the orioles, the tanagers, the cat-birds, the swallows and swifts, and some of the hardier warblers, while the great army of warblers delay their coming till the first and second weeks in May. And all the while we are having bird concerts, cantatas, oratorios, and opera festivals, mingled with some tragedy and a great deal of comedy, and there are love songs and cradle songs, matins and vespers, and twitterings expressive of every shade and variety of feeling.
I yield to the temptation to add a brief article entitled “Watching the Parade,” which was published in a New England journal in the summer of 1893, and contains a record of some observations made during the previous spring. By comparison with the preceding part of this chapter, it will indicate the versatile character of bird study in the same season of different years. I shall give it almost verbatim as first published, hoping the rather “free and easy” style will be generously overlooked by critical readers.
Every spring and autumn for many years I have been watching the parade; not a parade of soldiers, or of civic orders, or even of a menagerie; but one of far more interest to the naturalist,—the procession of the army in feathers. A wonderful cortége it is, this army in bright array; and every time you witness it, you add something new to your knowledge of bird life. The last spring has been no exception, although, when the pageant began, I wondered if I should see any new birds or hear any new songs, and even felt a little doubtful about it.
But quite early a new bird was added to my list. It was the blue-winged warbler, which carries about a scientific name big enough to break its dainty back. Just think of calling a tiny bird Helminthophila pinus! But happily it does not know its own name, and, like some of my readers, would not be able to pronounce it if it did, and therefore no serious harm is done. This bird may be known by the bright olive-green of its back, the pale blue of its wings, the pure yellow of its under parts, and the narrow black line running back through its eye. It seemed to be quite wary, yet I got near enough to see it catch insects on the wing like a wood-pewee, as well as pick them from the leaves of the trees.
The bird student must sometimes let problems go unsolved. For nearly, perhaps quite a week, three or four large, heavy-beaked birds flitted about in several tall tree-tops of the woods, but were so far up that, try as I would, I could not identify them even with my opera-glass. In my small collection of mounted birds there is a female evening grossbeak; and the tree-top flitters looked more like it than any other bird of my acquaintance. If they were evening grossbeaks, it was a rare find; for these birds are almost unknown in this part of the country, only a few having ever been discovered in this State. Their usual locale is thought to be west of Lake Superior. I was sorely tempted to use a gun, but decided that it was just as well not to know some things as to massacre an innocent bird.
However, other finds were more satisfactory. Strolling through the woods one day, I caught the notes of a bird song that did not sound familiar. Surely it was a vireo’s quaint, continuous lay; but which of the vireos could it be? It was different from any vireo minstrelsy I had ever heard. Peering about in the bushes for the author of those elusive notes, I at length espied a little bird form, and the next moment my glass revealed the blue-headed or solitary vireo. It was the first time I had ever heard this little vocalist sing in the spring, although we have met—he and I—on familiar terms every season for many years. Here is a query: Why was blue-head silent other years, and so tuneful that spring? For he was often heard after that day.
The song was varied and lively, sometimes running high in the scale, and had not that absent-minded air which marks the roundelay of the warbling vireo. It is much more intense and expressive, and some notes are quite like certain runs of the brown thrasher’s song. The bird did two other things that were a surprise: he chattered and scolded much like the ruby-crowned kinglet. Then he caught a miller, and, as it was too large to be swallowed whole, placed it under his claws precisely like a chickadee or blue jay, and pulled it to pieces. This was a new trick to me, nor have I ever read, in any of the bird manuals, of his taking his dinner in this way.
The red-eyed vireo also chanted a little roundel that spring, as he pursued his journey northward, his song being slower in movement and less expressive and varied than that of his cousin just referred to.
Indeed, the procession seemed to be especially musical during that spring. One day, in the last week in April, a new style of music rang out at the border of the woods, and I fairly trembled lest the jolly soloist should scud away before I could identify him; but he had no intention of making his escape, and giving the credit of his vocal efforts to somebody else in the bird world. At length I got my glass upon him. He proved to be the purple finch,—rosy little Mozart that he was! For years he has passed through these woods with the vernal procession, but this was the first time he had ever been obliging enough to sing in my hearing. And what a rolling, rollicking little song it was, just as full of good cheer as bird song could be! He continued his vocal rehearsal for many minutes on that day, but afterward he and his fellows were as mute as the inmates of a deaf and dumb asylum. A purple finch once sang here in the fall; but the music was quite harsh and squeaking, very different from his springtime melody.
One of the most beautiful birds that have a part in the vernal parade is the rose-breasted grossbeak,—a bird that you will recognize at once by his white-and-black coat and the rosy shield he so bravely bears on his bosom. In his summer home, farther north, I have often heard his vivacious music (this was in northern Indiana); but until the past spring he has always been silent as he passed through this neighborhood, save that he would sometimes utter his sharp, metallic Chip. However, on the fourteenth of May two of these grossbeaks sang a most vigorous duet in the grove near my house; and I wish you could have heard it, for it would have made you almost leap for joy, it was so jolly and rollicksome. At first you may be disposed to think the grossbeak’s song much like the robin’s, but you will soon find that it is finer in several respects, the tones being clearer and fuller, the utterance more rapid and varied, and the whole song much more spirited; and that is saying a good deal, considering Cock Robin’s cheery carols. No one should fail to hear this rosy-breasted minstrel, whatever else he may miss. It will make him feel that life is worth living; that if God made this bird so happy, he must intend that his rational creatures, who are of more value than a bird, should also be cheerful.
