KEEN PERCEPTIONS
Success in observing nature, as in so many other things, depends upon alertness of mind and quickness to take a hint. One's perceptive faculties must be like a trap lightly and delicately set; a touch must suffice to spring it. But how many people have I walked with, whose perceptions were rusty and unpracticed,—nothing less than a bear would spring their trap! All the finer play of nature, all the small deer, they miss. The little dramas and tragedies that are being enacted by the wild creatures in the fields and woods are more or less veiled and withdrawn; and the actors all stop when a spectator appears upon the scene. One must be able to interpret the signs, to penetrate the scenes, to put this and that together.
Then nature speaks a different language from our own; the successful observer translates this language into human speech. He knows the meaning of every sound, movement, gesture, and gives the human equivalent. Careless or hasty observers, on the other hand, make the mistake of reading their own thoughts or mental and emotional processes into nature; plans and purposes are attributed to the wild creatures which are quite beyond them. Some people in town saw an English sparrow tangled up in a horsehair, and suspended from a tree, with other sparrows fluttering and chattering about it. They concluded at once that the sparrows had executed
one of their number, doubtless for some crime. I have several times seen sparrows suspended in this way about their nesting and roosting places. Accidents happen to birds as well as to other folks. But they do not yet imitate us in the matter of capital punishment.
One day I saw a little bush sparrow fluttering along in the grass, disabled in some way, and a large number of its mates flitting and calling about it. I captured the bird, and, in doing so, its struggles in my hand broke the bond that held it—some kind of web or silken insect thread that tied together the quills of one wing. When I let it fly away, all its mates followed it as if wondering at the miracle that had been wrought. They no doubt experienced some sort of emotion. Birds sympathize with each other in their distress, and will make common cause against an enemy. Crows will pursue and fight a tame crow. They seem to look upon him as an alien and an enemy. He is never so shapely and bright and polished as his wild brother. He is more or less demoralized, and has lost caste. Probably a pack of wolves would in the same way destroy a tame wolf, should such an one appear in their midst. The wild creatures are human,—with a difference, a wide difference. They have the keenest powers of perception,—what observers they are! how quickly they take a hint—but they have little or no powers of reflection. The crows do not meet in parliaments and caucuses, as has been fancied, and try offenders, and discuss the tariff, or consider
ways and means. They are gregarious and social, and probably in the fall have something like a reunion of the tribe. At least their vast assemblages upon the hills at this season have a decidedly festive appearance.
The crow has fine manners. He always has the walk and air of a lord of the soil. One morning I put out some fresh meat upon the snow near my study window. Presently a crow came and carried it off, and alighted with it upon the ground in the vineyard. While he was eating of it, another crow came, and, alighting a few yards away, slowly walked up to within a few feet of this fellow and stopped. I expected to see a struggle over the food, as would have been the case with domestic fowls or animals. Nothing of the kind. The feeding crow stopped eating, regarded the other for a moment, made a gesture or two, and flew away. Then the second crow went up to the food, and proceeded to take his share. Presently the first crow came back, when each seized a portion of the food and flew away with it. Their mutual respect and good-will seemed perfect. Whether it really was so in our human sense, or whether it was simply an illustration of the instinct of mutual support which seems to prevail among gregarious birds, I know not. Birds that are solitary in their habits, like hawks or woodpeckers, behave quite differently toward each other in the presence of their food.
The lives of the wild creatures revolve about two facts or emotions, appetite and fear. Their keenness
in discovering food and in discovering danger are alike remarkable. But man can nearly always outwit them, because, while his perceptions are not as sharp, his power of reflection is so much greater. His cunning carries a great deal farther. The crow will quickly discover anything that looks like a trap or snare set to catch him, but it takes him a long time to see through the simplest contrivance. As I have above stated, I sometimes place meat on the snow in front of my study window to attract him. On one occasion, after a couple of crows had come to expect something there daily, I suspended a piece of meat by a string from a branch of the tree just over the spot where I usually placed the food. A crow soon discovered it, and came into the tree to see what it meant. His suspicions were aroused. There was some design in that suspended meat evidently. It was a trap to catch him. He surveyed it from every near branch. He peeked and pried, and was bent on penetrating the mystery. He flew to the ground, and walked about and surveyed it from all sides. Then he took a long walk down about the vineyard as if in hope of hitting upon some clew. Then he came to the tree again, and tried first one eye, then the other, upon it; then to the ground beneath; then he went away and came back; then his fellow came, and they both squinted and investigated, and then disappeared. Chickadees and woodpeckers would alight upon the meat and peck it swinging in the wind, but the crows were fearful. Does this show reflection? Perhaps
it does, but I look upon it rather as that instinct of fear and cunning so characteristic of the crow. Two days passed thus: every morning the crows came and surveyed the suspended meat from all points in the tree, and then went away. The third day I placed a large bone on the snow beneath the suspended morsel. Presently one of the crows appeared in the tree, and bent his eye upon the tempting bone. "The mystery deepens," he seemed to say to himself. But after half an hour's investigation, and after approaching several times within a few feet of the food upon the ground, he seemed to conclude there was no connection between it and the piece hanging by the string. So he finally walked up to it and fell to pecking it, flickering his wings all the time, as a sign of his watchfulness. He also turned up his eye, momentarily, to the piece in the air above, as if it might be some disguised sword of Damocles ready to fall upon him. Soon his mate came and alighted on a low branch of the tree. The feeding crow regarded him a moment, and then flew up to his side, as if to give him a turn at the meat. But he refused to run the risk. He evidently looked upon the whole thing as a delusion and a snare, and presently went away, and his mate followed him. Then I placed the bone in one of the main forks of the tree, but the crows kept at a safe distance from it. Then I put it back to the ground, but they grew more and more suspicious; some evil intent in it all, they thought. Finally a dog carried off the bone, and the crows ceased to visit the tree.
