As I sit here day after day, bending over my work, I get many glimpses of the little rills of wild life that circulate about me. The feature of it that impresses me most is the life of fear that most of the wild creatures lead. They are as alert and cautious as are the picket-lines of opposing armies. Just over the line of stone wall in the orchard a woodchuck comes hesitatingly out of his hole and goes nibbling in the grass not fifty feet away. How alert and watchful he is! Every few moments he sits upright and takes an observation, then resumes his feeding. When I make a slight noise he rushes to the cover of the stone wall. Then, as no danger appears, he climbs to the top of it and looks in my direction. As I move as if to get up, he drops back quietly to his hole.
A chipmunk comes along on the stone wall, hurrying somewhere on an important errand, but changing his course every moment. He runs on the top of the wall, then along its side, then into it and through it and out on the other side, pausing every few seconds and looking and listening, careful not to expose himself long in any one position, really skulking and hiding all along his journey. His enemies are keen and watchful and likely to appear at any moment, and he knows it, not so much by experience as by instinct. His young are timid and watchful the first time they emerge from the den into the light of day.
Then a red squirrel comes spinning along. By jerks and nervous, spasmodic spurts he rushes along from cover to cover like a soldier dodging the enemy's bullets. When he discovers me, he pauses, and with one paw on his heart appears to press a button, that lets off a flood of snickering, explosive sounds that seem like ridicule of me and my work. Failing to get any response from me, he presently turns, and, springing from the wall to the bending branch of a near apple-tree, he rushes up and disappears amid the foliage. Presently I see him on the end of a branch, where he seizes a green apple not yet a third grown, and, darting down to a large horizontal branch, sits up with the apple in his paws and proceeds to chip it up for the pale, unripe seeds at its core, all the time keenly alive to possible dangers that may surround him. What a nervous, hustling, highstrung creature he is—a live wire at all times and places! That pert curl of the end of his tail, as he sits chipping the apple or cutting through the shell of a nut, is expressive of his character. What a contrast his nervous and explosive activity presents to the more sedate and dignified life of the gray squirrel! One of these passed us only a few yards away on our walk in the woods the other day—a long, undulating line of soft gray, silent as a spirit and graceful as a wave on the beach.
A little later, in the fine, slow-falling rain, a rabbit suddenly emerges into my field of vision fifty feet away. How timid and scared she looks! She pauses a moment amid the weeds, then hops a yard or two and pauses again, then passes under the bars and hesitates on the edge of a more open and exposed place immediately in front of me. Here she works her nose, feeling of every current of air, analyzing every scent to see if danger is near. Apparently detecting something suspicious in the currents that drift from my direction, she turns back, pauses again, works her nose as before, then hurries out of my sight.
Yesterday I saw a rat stealing green peas from my garden in the open day. He darted out of the stone wall six or eight feet away to the row of peas, rushed about nervously among the vines; then, before I could seize my rifle, darted back to the cover of the wall. Once I cautiously approached his hiding-place in the wall and waited. Presently his head emerged from the line of weeds by the fence, his nose began working anxiously, he sifted and resifted the air with it, and then quickly withdrew; his nose had detected me, but his eye had not. The touchstone of most animals is the nose, and not the eye. The eye quickly detects objects in motion, but not those at rest; this is the function of the nose.
A highhole alights on the ground in full view in the orchard twenty yards away, and, spying my motionless figure, pauses and regards me long and intently. His eye serves him, and not his nose. Finally concluding that I am not dangerous, he stoops to the turf for his beloved ants and other insects, but lifts his head every few seconds to see that no danger is imminent. Not one moment is he off his guard. A hawk may suddenly swoop from the air above, or a four-footed foe approach from any side. I have seen a sharp-shinned hawk pick up a highhole from the turf in a twinkling under just such conditions. What a contrast between the anxious behavior of these wild creatures and the ease and indifference of the grazing cattle!
All the wild creatures evidently regard me with mingled feelings of curiosity and distrust. A song sparrow hops and flirts and attitudinizes and peers at me from the door-sill, wondering if there is any harm in me. A phœbe-bird comes in and flits about, disturbed by my presence. For the third or fourth time this season, I think, she is planning a nest. In June she began one over a window on the porch where I sleep in the open air. She had the foundation laid when I appeared, and was not a little disturbed by my presence, especially in the early morning, when I wanted to sleep and she wanted to work. She let fall some of her mortar upon me, but at least I had no fear of a falling brick. She gradually got used to me, and her work was progressing into the moss stage when two women appeared and made their beds upon the porch, and in the morning went to and fro with brooms, of course. Then Phœbe seemed to say to herself, "This is too much," and she left her unfinished nest and resorted to the empty hay-barn. Here she built a nest on one of the bark-covered end timbers halfway up the big mow, not being quite as used to barns and the exigencies of haying-times as swallows are, who build their mud nests against the rafters in the peak. She had deposited her eggs, when the haymakers began pitching hay into the space beneath her; sweating, hurrying haymakers do not see or regard the rights or wants of little birds. Like a rising tide the fragrant hay rose and covered the timber and the nest, and crept on up toward the swallow's unfledged family in the peak, but did not quite reach it.
Phœbe and her mate hung about the barn disconsolate for days, and now, ten days later, she is hovering about my open door on the floor below, evidently prospecting for another building-site. I hope she will find me so quiet and my air so friendly that she will choose a niche on the hewn timber over my head. Just this moment I saw her snap up a flying "miller" in the orchard a few rods away. She was compelled to swoop four times before she intercepted that little moth in its unsteady, zigzagging flight. She is an expert at this sort of thing; it is her business to take her game on the wing; but the moths are experts in zigzag flying, and Phœbe missed her mark three times. I heard the snap of her beak at each swoop. It is almost impossible for any insectivorous bird except a flycatcher to take a moth or a butterfly on the wing.
Last year in August the junco, or common snowbird, came into the big barn and built her nest in the side of the haymow, only a few feet from me. The clean, fragrant hay attracted her as it had attracted me. One would have thought that in a haymow she had nesting material near at hand. But no; her nest-building instincts had to take the old rut; she must bring her own material from without; the haymow was only the mossy bank or the wood-side turf where her species had hidden their nests for untold generations. She did not weave one spear of the farmer's hay into her nest, but brought in the usual bits of dry grass and weeds and horsehair and shaped the fabric after the old pattern, tucking it well in under the drooping locks of hay. As I sat morning after morning weaving my thoughts together and looking out of the great barn doorway into sunlit fields, the junco wove her straws and horsehairs, and deposited there on three successive days her three exquisite eggs.
Why the bird departed so widely from the usual habits of nest-building of her species, who can tell? I had never before seen a junco's nest except on the ground in remote fields, or in mossy banks by the side of mountain roads. This nest is the finest to be found upon the ground, its usual lining of horsehair makes its interior especially smooth and shapely, and the nest in the haymow showed only a little falling-off, as is usually the case in the second nest of the season. The songs of the birds, the construction of their nests, and the number of their eggs taper off as the season wanes.
