Having wearied of annoying the enemy, he sprang back to the ladder, descended by the table and trunk to the floor as he had gone up, without a moment's hesitation as to the way, which proved him to possess unusual intelligence. He did not take the trouble to climb down, but put his two feet together and jumped heavily like a child, a very odd movement for a bird. It was his constant habit in the cage to jump from the perch to the floor, and from one that was two inches above the tray he often stepped down backwards, which I never before saw a bird do. When after three hours of exploration he returned to his home, the door was closed and the cage hung up. He was satisfied with his first outing, and refreshed himself with a nap at once. But the first thing the next morning he came down to his door and pecked the wires, looking over at me most intelligently, plainly asking to have it opened. He never mistook the position of the door, and if knocking had not the desired effect, he took hold of a wire and shook and rattled it till he was attended to. It was interesting to see how familiar he suddenly became, when no effort had been made to induce him to be so. I never had so much trouble to win the confidence of a bird, but when won, the surrender was complete. He came up to me freely and allowed me to catch him in my hand without resistance, which is very uncommon. (Perhaps I ought to say that I do not try to tame my birds.) He displayed a child-like, confiding disposition, both in his unreasoning terror at first, and his unquestioning faith at last. These investigations were conducted without a sound, for the bird was entirely silent while awake. But there came a day when he made a curious exhibition of his ability. It was the ninth of February, and the goldfinch was calling, as he often did. The woodpecker sat on his perch with wings held tightly against his sides, "humped" up as though he were high-shouldered. The plumage of his breast was puffed out so broadly that it came over the wings, and in a front view completely hid them, while the feathers of his shoulders were erected till he resembled a lady with a fur shoulder cape. Withal, his head was drawn down to his body, and his beak pointed upward at an angle of forty-five degrees. In this peculiar and absurd position he began a strange little song, ludicrously weak and low for a bird of his size. The tones were delivered in a sharp staccato style, like "picking" the strings of a violin very softly, several notes uttered with queer sidewise jerks of the head, and eyes apparently fixed on the goldfinch. After a phrase or two he scraped his bill violently and then began again.
