The English sparrow will sometimes worst the bluebird by getting possession of the box or cavity ahead of him. Once inside, the sparrow can hold the fort, and the bluebird will soon give up the siege; but in a fair field and no favor, the native bird will quickly rout the foreigner. Speaking of birds that build in cavities reminds me of a curious trait the high-hole has developed in my vicinity, one which I have never noticed or heard of elsewhere. It drills into buildings and steeples and telegraph poles, and in some instances makes itself a serious nuisance. One season the large imitation Greek columns of an unoccupied old-fashioned summer residence near me were badly marred by them. The bird bored into one column, and finding the cavity—a foot or more across—not just what it was looking for, cut into another one, and still into another. Then he bored into the ice-house on the premises, and in the sawdust filling between the outer and inner sheathing found a place to his liking. One bird seemed like a monomaniac, and drilled holes up and down and right and left as if possessed of an evil spirit. It is quite probable that if a high-hole or other woodpecker should go crazy, it would take to just this sort of thing, drilling into seasoned timber till it used its strength up. The one I refer to would cut through a dry hemlock board in a very short time, making the slivers fly. The sound was like that of a carpenter's hammer. It may have been that he was an unmated bird, a bachelor whose suit had not prospered that season, and who was giving vent to his outraged instincts in drilling these mock nesting-places. XVII THE WAYS OF SPORTSMEN I have often had occasion to notice how much more intelligence the bird carries in its eye than does the animal or quadruped. The animal will see you, too, if you are moving, but if you stand quite still even the wary fox will pass within a few yards of you and not know you from a stump, unless the wind brings him your scent. But a crow or a hawk will discern you when you think yourself quite hidden. His eye is as keen as the fox's sense of smell, and seems fairly to penetrate veils and screens. Most of the water-fowl are equally sharp-eyed. The chief reliance of the animals for their safety, as well as for their food, is upon the keenness of their scent, while the fowls of the air depend mainly upon the eye. A hunter out in Missouri relates how closely a deer approached him one day in the woods. The hunter was standing on the top of a log, about four feet from the ground, when the deer bounded playfully into a glade in the forest, a couple of hundred yards away. The animal began to feed and to move slowly toward the hunter. He was on the alert, but did not see or scent his enemy. He never took a bite of grass, says the sportsman, without first putting his nose to it, and then instantly raising his head and looking about.
