Another little charmer of the woodland, especially of thick second-growth timber, is the blue-winged warbler, which glories in the high-sounding Latin name of Helminthophila pinus. Wherever seen, he would attract attention on account of the peculiar cut and color of his clothes. A conspicuous black line reaching from the corner of the mouth back through the eye is a diagnostic feature of his plumage, while his crown and breast gleam in bright yellow, almost golden in the sunshine; his wings and tail are blue-gray, with some white trimmings, and his back and rump are bright olive There you have an array of colors that makes a picture indeed. Madame Blue-wing wears the same pattern as her lord, but the hues are less brilliant.
The manners of Sir Blue-wing—I call him so because of his distinguished air—are interesting, for they differ, in one respect at least, from those of most of the other warblers of my acquaintance. He flits about among the branches in rather a leisurely way—for a warbler; but his main characteristic is his unwarbler-like fashion of clinging back downward to the under side of the twigs, after the manner of the chickadee, in order to secure the nits and worms under the leaves. He acts decidedly like a diminutive trapeze performer.
His song consists of an insect-like buzz, divided into stanzas of two syllables each, with a pensive strain running through it, as if the heart of the little singer were filled with sadness. While it sounds rather faint at a distance, close at hand it has a strangely penetrating quality.
Although my numerous efforts to find a blue-wing's nest were unavailing, I had the satisfaction of proving beyond doubt that these birds breed in northeastern Kansas. A quaint, squeaking call attracted my attention one day, and I found that it proceeded from the throat of a young blue-wing perched in the bushes, for presently the mamma came and thrust a morsel into the open mouth of the bantling. Some young birds sit quietly and patiently, waiting for their rations, and utter only a faint twitter when they are fed; but the youthful blue-wings are not of so contented and silent a disposition. On the contrary, they are noisy little fellows, making their presence known to friend and foe alike, although they are very careful never to permit the human observer to come too close. They are duly warned of danger by their ever-vigilant parents. Sometimes a youngster will sit on the same perch for a long time, preening his feathers and uttering a little call at intervals, just to keep in practice, as it were; while at other times he will pursue his parents about in the woods, loudly demanding his dinner. One season I succeeded in finding at least five pairs of these warblers, in company with their clamorous broods. The nest is set on the ground in the bushes and grass of second-growth timber tracts. Lined with tendrils and fine strips of bark, it is "firmly wrapped with numerous leaves, whose stems point upward." Another haunter of the dusky depths of the woods is the ovenbird. His song is one of the most peculiar in warblerdom. Beginning in moderate tones, it grows louder and louder as it nears the end, and really seems like a voice moving toward you. This bird also walks about in the woods, and does not hop, as most of his relatives do. As he walks about on his leafy carpet, his head erect, he has quite a consequential air. He derives his name from the fact that his nest, set on the ground, is globular in form, with the entrance at one side, giving it the appearance of a small oven.
The gay redstarts, which seem to be so tame and confiding in the early spring, turn into veritable eremites in the breeding season, seeking the most secluded portions of the woods as their habitat. Their little nests are harder to find than one would suppose; yet I have had the good fortune to watch two females erecting the walls of their tiny cottages, and a pretty sight it was.
The redstart has some interesting ways. One of them is his habit of spreading out his wings and tail as he perches or flits about in the trees, as if he were anxious to display the fiery trimmings that so elegantly set off his little black suit. Blood will tell, for I have seen the young redstarts imitating their parents by spreading out their odd, croppy tails in a comical way.
How early in life young birds are taught some of the lessons that are needful for their own safety! One day I heard a young redstart chirping for his dinner. I quietly thrust my head into the thicket, and soon espied the birdkin perched on a twig only about a rod away. He either did not see me, or else decided that I was not a bugaboo. A few minutes later the mother darted into the enclosure and fed her baby. She was too much absorbed in her duties to notice me until the repast was over; then she suddenly caught sight of her unwelcome caller. She stood transfixed with astonishment for one breathless moment, then uttered a piercing cry of alarm that sent the little one dashing away like a streak of lightning. Plainly the youngster understood his mamma's signal, for until she uttered it he had sat perfectly quiet and unconcerned, perhaps not even aware of my presence. Birds are taught the language of fear at a tender age. Of course they learn it so readily because there is a basis of timidity in their natures, implanted by heredity.
