This boundary made by the tanager was never changed, but in the rest of the cage the goldfinch made himself at home, and at once assumed the position of protector. Seeing that the owner did not,--and sure it was somebody's duty,--he began to guard the door, warning away any one who wished to enter, with harsh scolding, fluttering of wings, and swelling up of his little body, amusing to see. The boldest bird in the room was awed by these demonstrations coming from the inside as though the cage were his own. The tanager looked on all this with some interest, but expressed no more gratitude at being protected than he had resentment at being driven from the bath. Soon I noticed a certain chattering talk from the small bird that he had never indulged in excepting to another of his kind--his companion when he first came to me. It was very low but almost continuous, and was plainly addressed to the tanager. As his friendliness progressed, he found the lower perch too far from his charmer, and not being allowed to sit beside him he took to clinging upon the outside of the cage as near to the tanager's usual seat as he could get. The only perching place he had there was a band of tin that held the wires steady, but in spite of what must have been the discomfort of the position, there he hung by the hour, talking, calling, and looking at his idol within. He left the spot only to eat and bathe, and I think if the cage had been supplied with seed he would never have gone at all. When the bird inside hopped to the perch at the other end of the cage, which was the extent of his wanderings, the finch at once followed on the outside, always placing himself as near as possible. It was really touching, to all but the object of it, who took it in the most indifferent way. When the tanager went down to eat, his escort accompanied him as far as the door perch, where he stood and looked on earnestly, ready to return to his old place the moment the luncheon was finished. On the rare occasions that the self-elected hermit went out, the goldfinch displayed great concern, evidently preferring to have his favorite at home where he could defend him. He flew uneasily across from the cage to his side, then back, as if to show him the way. He also desired to watch the empty house, to preserve it from intrusion, but was constantly divided between his duties of special porter, and bodyguard. But he did his best, even then; he followed the wanderer. If the tanager went to a perch the goldfinch at once alighted on the same, about a foot away, and sidled up as near as he was allowed. He was free to come within about three inches, but nearer he was driven off, so the little fellow placed himself at this distance and there stayed patiently as long as his friend remained. If the latter had been more responsive, I believe the goldfinch would have nestled up against him.
