The bird was perhaps the most intelligent one I ever watched, the cat-bird being his only rival in that regard. Fear was unknown to him, and from the moment of his arrival he was interested in everything that took place around him; looking at each bird in succession; making close study of every member of the family; noticing the sounds of the street, including the sparrow broils on the porch-roof; in fact, extremely wide-awake and observing. To the goldfinch's song he gave attention, standing motionless except for a slight nervous jerk of one wing, looking and listening as intently as though studying the notes for future use. The freedom of the birds in the room surprised him, as he showed plainly by the eager glances with which he followed every movement and marked each act. Upon joining the party of the free, he took note of pictures in a newspaper, distinguishing objects in the cut, which he tried to pick up, as a small wheel and a bar. In colors he had a choice, and his selection was red; from a vase of roses of many hues he never failed to draw out the red one to pull it to pieces on the floor.
Liberty the mocking-bird emphatically enjoyed, and at once recognized a string attached to his door as a device to deprive him of it; after vainly trying to pick it apart, he betook himself to another cage, and refused to go back to his own. In any strange cage he stood quietly while I walked up to him, and made no attempt to leave his quarters, knowing perfectly well that I did not care to shut the door upon him; but when at home I could not lift my hands, or make the slightest movement, without causing him to dart out of the cage instantly. Having contention with his room-mates about the bits of apple put out for all to enjoy, he often carried away a piece to eat at his leisure. From habit he flew first to the top of a cage, that being his favorite perching place; but he evidently appreciated that, if he dropped the morsel, he should lose it through the wires; and after looking one side and the other, plainly satisfying himself of this fact, he went to the table with it. I never before saw a bird who did not have to learn the treacherous nature of cage roofs by experience. He appeared to work things out in his mind,--to reason, in truth. One cold morning in spring, when the furnace fire was out, a large, brilliant lamp was put by his cage to take off the chill, for he felt changes keenly. He seemed to understand it at once, and though, no doubt, it was his first experience of warmth from a light, he drew as near it as possible, and remained there perfectly quiet until the sun warmed the room and it was removed. Fear, as I said, he knew not, coming freely upon the desk, or even upon my lap, after apple or bread, or anything he fancied.
