The tanager sometimes strayed into a strange cage, and then the anxious guard followed to the steps and even within, talking earnestly, and no doubt pointing out the danger, yet if the owner unexpectedly appeared he met him at the threshold and fiercely defended the door against the proprietor himself. Occasionally the erratic recluse went to the floor--a place never visited by his little attendant, whose trouble was almost painful to see. He at once placed himself on the lowest perch, stretched out and looked over, following every movement with his eyes, in silence, as though the danger was too great to allow conversation, and when his charge returned to a perch, he uttered a loud and joyous call as though some peril had been escaped. The stanch little friend had many chances to show his loyalty. The other birds in the room were not slow to take advantage of one who never defended himself. In particular a Brazilian cardinal, a bold saucy fellow with a scarlet pointed crest and a loud voice, evidently considered the tanager cage common ground, open to everybody, until the goldfinch undertook its defense. It was amusing to see the small bird stand just inside, and rage, puff himself out, wave his wings, and fairly drive away the foe. So impertinent was the Brazilian that the finch declared general war upon him, and actually chased his big antagonist around the room and away from his favorite perches, hovering over his head, and flying around it in small circles, trying to peck it, till he flew away defeated, probably because he was too much amazed to think of resisting. This was not, however, the worst enemy he had to deal with. Next door to the tanager lived a robin, a big, rollicking, fun-loving fellow who considered such a retiring personage fair game. His pleasure was to see that the tanager went out every day, and he made it his business to enforce the regulation he had set up. His tactics were to jump upon the roof of the cage, coming down violently just over the head of the tanager, who, of course, hopped quickly to the other perch. Then the robin began a mad war-dance across the cage, wings held up, tail spread, bill clattering, and altogether looking as full of mischief as any bad boy one ever saw, while the tanager went wild below, flying in a panic back and forth, but not for some time thinking of leaving the cage. The instant this performance began, the little champion was upon him; he alighted at one end of the short tramping ground on the cage, and met his big foe with open beak and every sign of war. The robin simply lowered his head and went for him, and the little bird had to fly. He pluckily returned at once to the other end and faced him again.
