There are in North America four other species of the genus Leucosticte; the Aleutian, whose habitat is the Aleutian and Prybilof islands and east as far as the island of Kadiak; the gray-crowned, which breeds in British America near the Rocky Mountains, comes to Colorado in winter, and has been taken as far east as western Iowa; the Hepburn, dwelling chiefly in the mountain ranges of the Pacific coast, breeding mostly in the far North, and in winter coming as far south and east as Nevada and Colorado; and, lastly, the black leucosticte, which winters in the central latitudes in the Rocky Mountains and whose summer range and breeding home is unknown to men of science.
HAPPENINGS BY THE WAY
If one were to keep on writing monographs of all our interesting avian species, the books that would result would make a good-sized library. The few examples that have been given will illustrate what can be done in this direction with the help of the field glass and the handbook. A few chapters will now be given on what might be called "odds and ends of bird life," and these are written not only for the information they may impart, but also for the purpose of showing how many interesting facts can be gathered along the way by the method of bird study commended in our opening chapter.
The prince of American ornithologists, Dr. Elliott Coues, has somewhere said that he would travel a long distance to discover a new kind of bird, or even to ascertain a new fact about a familiar species. I would applaud and echo that sentiment, for by all means let us have bird news that really is news, instead of revamping the familiar facts again and again, as some amateurish writers do. While I am not able to add any new species to science, I have made note of many pleasing incidents in the bird realm, and these, I venture to hope, may be of not a little general interest.

There is the companionable white-breasted nuthatch which goes scudding up and down the tree trunks with as much ease and aplomb as a fly gliding over a window-pane. I have already told you something about him. I had long been aware that he wedged grains of corn, sunflower seeds, and kernels of nuts in the crannies of the bark; but one day he invented a trick that was a surprise to me. It occurred at a summer resort in northern Indiana, where I noticed a nuthatch hitching up and down and around the slender stem of a sapling, pausing at intervals to thrust something into the crevices of the bark. My curiosity led me to pry into the bird's affairs. Stepping smartly forward, I drove him away, not heeding his vigorous protest of "yank, yank," and examined the bark of the sapling. What did I discover? A colony of black ants were scuttling up and down the tree, apparently under stress of great excitement; and good reason they had, for here and there one of their number was tightly wedged into a chink of the bark, often doubled up into a bow or an angle. They were not killed, at least not all of them, for they were still wiggling their legs and antennas; but they were evidently benumbed, or some of their backs were broken, and they were fastened so securely in the fissures that they could not escape. Does it not look as if the forehanded nuthatch was laying by a supply of ants for a coming time of hunger?
One day a family of wood pewees visited the dooryard of my tent. A multitude of gnats circling about in the air, seemed to be precisely to the taste of the pewee parents and their hungry bairns. The bantlings sat chirping in the saplings, or flitted from twig to twig, twinkling their wings in the coaxing way that is characteristic of young birds, while the papa and mamma swung out into the air, nabbed the insects on the wing, and flew back to the trees, describing many circles, ellipses, and festoons of rare grace and beauty. The snapping of their mandibles could often be heard as they closed upon the fated insects. Most of the gnats thus captured were thrust into the mouths of the young birds, the parents dashing up to them and feeding them without alighting. As lavish a minstrel as the pewee pater familias is under most circumstances, that morning he was too busy to tune his wind harp.
Speaking of the voracious appetites of birds, as exhibited by the young pewees, which never seemed to get enough, I am reminded of something I witnessed one day in a deep, wooded hollow. A red-eyed vireo suddenly appeared in the branches above me, holding an immense green worm in his beak. Then followed a tussle for the "upper hand" that was worth seeing. The bird, holding its squirming victim by one end, proceeded to beat it against the limb, though it was almost too big and recalcitrant for him to handle. Presently the vireo, after a good deal of effort, succeeded in passing his quarry through his bill from end to end, thus reducing it to somewhat smaller dimensions. Still, it was a large morsel for so small a diner.
However, there were some intimations that the bird intended to bolt the worm whole. And that was just what he was planning to do! What a struggle ensued! I would have wagered that the little gourmand had reckoned without his host when he undertook to swallow that immense worm. He twisted his neck this way and that, gulped and squeezed and pried, until I feared he would burst his throat open. At length the worm was partly bolted, but it seemed to stick fast, and the bird stood there with his mandibles pressed far apart, the end of his dinner bulging out of his mouth, and I felt uneasy for a time lest he should choke to death before my very eyes. But, after resting a minute, he gave his neck a number of convulsive twists, and at last succeeded in forcing the unwilling worm down his throat, after which he wiped his bill on the limb with a self-satisfied air and flitted away as happy as a lark, knowing that his faithful craw would do the rest.
