Observing that the goldfinch alone was not able to keep the robin away, I provided the cage with a roof of paper, which is usually a perfect protection, since birds dislike the rustle. It did not dismay this naughty fellow, however; on the contrary, it gave an added zest because of that very quality. He pranced across it in glee, making a great noise, and when the violence of his movements pushed it aside, he peered down on the tanager, who stood panting. The sight pleased him, and he resumed his pranks; he lifted the handle of the cage and let it drop with a clatter; he jerked off bits of paper and dropped them into the cage, and in every way showed a very mischievous spirit. Meanwhile, all through the confusion the goldfinch scolded furiously, flying around to get a peck at him, and in every way challenging him to fight. Occasionally, when he became too troublesome, the robin turned and snapped his beak at him, but did not choose to leave the bigger game. When at last he tired of his fun, or was driven away, the goldfinch flew to the side of the cage where the frightened tanager had taken refuge, though there was not even a strip of tin to hold on, uttered his loud cheerful call several times, plainly congratulating and reassuring him, and telling him all was safe; and here he clung with difficulty to the upright wires, all the time slipping down, till the tanager went to the upper regions again. Every time the robin so much as flew past, the tireless little fellow rushed out at him, scolding. When finally the robin went into his own cage, and the tanager returned to his usual place, the goldfinch at once assumed his uncomfortable perch and sang a loud sweet song, wriggling his body from side to side, and expressing triumph and delight in a remarkable way. The approach of spring made a change in the tanager. He had not so completely given up the world as it appeared. He began to chirp, to call, and at last to sing. He was still so shy he went down behind his screen to sing, but sing he must and did. Now, too, he began to resent the attentions of his admirer, occasionally giving the poor little toes a nip, as they clung to the tin band near his seat. He also went out now, and turned an open beak upon his friend. From simply enduring him, he suddenly began offensive operations against him. Poor little lover! an ungrateful peck did not drive him away, but simply made him move a little farther off, and stopped his gentle twittering talk a while. But the tanager grew more and more belligerent. He came out every day, took soaking baths, and returned to his examination of the windows, for the trees were green outside, and plainly he longed to be on them. He stood and looked out, and called, and held his wings up level with his back, fluttering them gently.
