A boy brought me a dead bird the other morning which his father had picked up on the railroad. It had probably been killed by striking the telegraph wires. As it was a bird the like of which he had never seen before, he wanted to know its name. It was a wee bird, mottled gray and brown like nearly all our ground birds, as the sparrows, the meadowlark, the quail: a color that makes the bird practically invisible to its enemies in the air above. Unlike the common sparrows, its little round wings were edged with yellow, with a tinge of yellow on its shoulders; hence its name, the yellow-winged sparrow. It has also a yellowish line over the eye. It is by no means a common bird, though there are probably few farms in the Middle and Eastern States upon which one could not be found. It is one of the birds to be looked for. Ordinary observers do not see it or hear it. It is small, shy, in every way inconspicuous. Its song is more like that of an insect than that of any other of our birds. If you hear in the fields in May and June a fine, stridulous song like that of a big grasshopper, it probably proceeds from this bird. Move in the direction of it and you will see the little brown bird flit a few yards before you. For several mornings lately I have heard and seen one on a dry, gravelly hillock in a field. Each time he has been near the path where I walk. Unless your ear is on the alert you will miss his song. Amid the other bird songs of May heard afield it is like a tiny, obscure plant amid tall, rank growths. The bird affords a capital subject for the country boy, or town boy, either, when he goes to the country, to exercise his powers of observation upon. If he finds this bird he will find a good many other interesting things. He may find the savanna sparrow also, which closely resembles the bird he is looking for. It is a trifle larger, has more bay about the wings, and is more common toward the coast. Its yellow markings are nearly the same. There is also a variety of the yellow-winged sparrow called Henslow's yellow-winged sparrow, but it bears so close a resemblance to the first-named that it requires a professional ornithologist to distinguish them. I confess I have never identified it. I never see the yellow-wing without being reminded of a miniature meadowlark. Its short tail, its round wings, its long and strong legs and feet, its short beak, its mottled coat, the touch of yellow, as if he had just rubbed against a newly-opened dandelion, but in this case on the wings instead of on the breast, the quality of its voice, and its general shape and habits, all suggest a tiny edition of this large emphatic walker of our meadows. The song of this little sparrow is like the words "chick, chick-a-su-su," uttered with a peculiar buzzing sound. Its nest is placed upon the ground in the open field, with four or five speckled eggs. The eggs are rounder and their ground color whiter than the eggs of other sparrows.
