I do not think many animals show their kinship to us by exhibiting the trait I am here discussing. Probably birds do not show it at all. I have seen a nest-building robin baffled and delayed, day after day, by the wind that swept away the straws and rubbish she carried to the top of a timber under my porch. But she did not seem to lose her temper. She did not spitefully reclaim the straws and strings that would persist in falling to the porch floors, but cheerfully went away in search of more. So I have seen a wood thrush time after time carrying the same piece of paper to a branch from which the breeze dislodged it, without any evidence of impatience. It is true that when a string or a horsehair which a bird is carrying to its nest gets caught in a branch, the bird tugs at it again and again to free it from entanglement, but I have never seen any evidence of impatience or spite against branch or string, as would be pretty sure to be the case did my string show such a spirit of perversity. Why your dog bites the stone which you roll for him when he has found it, or gnaws the stick you throw, is not quite clear, unless it be from the instinct of his primitive ancestors to bite and kill the game run down in the chase. Or is the dog trying to punish the stick or stone because it will not roll or fly for him? The dog is often quick to resent a kick, be it from man or beast, but I have never known him to show anger at the door that slammed to and hit him. Probably, if the door held him by his tail or his limb, it would quickly receive the imprint of his teeth.
In reading Bostock on the "Training of Wild Animals," my attention was arrested by the remark that his performing lions and tigers are liable to suffer from "stage fright," like ordinary mortals, but that "once thoroughly accustomed to the stage, they seem to find in it a sort of intoxication well known to a species higher in the order of nature;" and furthermore, that "nearly all trainers assert that animals are affected by the attitude of an audience, that they are stimulated by the applause of an enthusiastic house, and perform indifferently before a cold audience." If all this is not mere fancy, but is really a fact capable of verification, it shows another human trait in animals that one would not expect to find there. Bears seem to show more human nature than most other animals. Bostock says that they evidently love to show off before an audience: "The conceit and good opinion of themselves, which some performing bears have, is absolutely ridiculous." A trainer once trained a young bear to climb a ladder and set free the American flag, and so proud did the bear become of his accomplishment, that whenever any one was looking on he would go through the whole performance by himself, "evidently simply for the pleasure of doing it." Of course there is room for much fancy here on the part of the spectator, but bears are in so many ways—in their play, in their boxing, in their walking—such grotesque parodies of man, that one is induced to accept the trainer's statements as containing a measure of truth.

THE DOWNY WOODPECKER
I
It always gives me a little pleasurable emotion when I see in the autumn woods where the downy woodpecker has just been excavating his winter quarters in a dead limb or tree-trunk. I am walking along a trail or wood-road when I see something like coarse new sawdust scattered on the ground. I know at once what carpenter has been at work in the trees overhead, and I proceed to scrutinize the trunks and branches. Presently I am sure to detect a new round hole about an inch and a half in diameter on the under side of a dead limb, or in a small tree-trunk. This is Downy's cabin, where he expects to spend the winter nights, and a part of the stormy days, too.
When he excavates it in an upright tree-trunk, he usually chooses a spot beneath a limb; the limb forms a sort of rude hood, and prevents the rainwater from running down into it. It is a snug and pretty retreat, and a very safe one, I think. I doubt whether the driving snow ever reaches him, and no predatory owl could hook him out with its claw. Near town or in town the English sparrow would probably drive him out; but in the woods, I think, he is rarely molested, though in one instance I knew him to be dispossessed by a flying squirrel.
On stormy days I have known Downy to return to his chamber in mid-afternoon, and to lie abed there till ten in the morning.
