The first chipmunk in March is as sure a token of the spring as the first bluebird or the first robin; and it is quite as welcome. Some genial influence has found him out there in his burrow, deep under the ground, and waked him up, and enticed him forth into the light of day. The red squirrel has been more or less active all winter; his track has dotted the surface of every new-fallen snow throughout the season. But the chipmunk retired from view early in December, and has passed the rigorous months in his nest, beside his hoard of nuts, some feet underground, and hence, when he emerges in March, and is seen upon his little journeys along the fences, or perched upon a log or rock near his hole in the woods, it is another sign that spring is at hand. His store of nuts may or may not be all consumed; it is certain that he is no sluggard, to sleep away these first bright warm days. Before the first crocus is out of the ground, you may look for the first chipmunk. When I hear the little downy woodpecker begin his spring drumming, then I know the chipmunk is due. He cannot sleep after that challenge of the woodpecker reaches his ear. Apparently the first thing he does on coming forth, as soon as he is sure of himself, is to go courting. So far as I have observed, the love-making of the chipmunk occurs in March. A single female will attract all the males in the vicinity. One early March day I was at work for several hours near a stone fence, where a female had apparently taken up her quarters. What a train of suitors she had that day! how they hurried up and down, often giving each other a spiteful slap or bite as they passed. The young are born in May, four or five at a birth. The chipmunk is quite a solitary creature; I have never known more than one to occupy the same den. Apparently no two can agree to live together. What a clean, pert, dapper, nervous little fellow he is! How fast his heart beats, as he stands up on the wall by the roadside, and, with hands spread out upon his breast, regards you intently! A movement of your arm, and he darts into the wall with a saucy _chip-r-r_, which has the effect of slamming the door behind him. On some still day in autumn, the nutty days, the woods will often be pervaded by an undertone of sound, produced by their multitudinous clucking, as they sit near their dens. It is one of the characteristic sounds of fall. The chipmunk has many enemies, such as cats, weasels, black snakes, hawks, and owls. One season one had his den in the side of the bank near my study. As I stood regarding his goings and comings, one October morning, I saw him, when a few yards away from his hole, turn and retreat with all speed. As he darted beneath the sod, a shrike swooped down and hovered a moment on the wing just over the hole where he had disappeared. I doubt if the shrike could have killed him, but it certainly gave him a good fright.
