One thing still remained unsettled: the mocking-bird decided to change his residence. No reason was apparent, but he preferred a special place in the room, a certain end of a particular shelf; and no matter what cage was there, he insisted on taking possession. The day he determined on this removal, he went in while the resident--the thrush--was out, and, having eaten, proceeded to the upper perches, and began jumping back and forth on them, as if at home. In due time the owner returned, visited the food-dishes, and started for the upper regions, but was met by a threatening attitude from the bird already there. He seemed to think the matter not worth quarreling over, since he readily settled himself on the middle perch, where he made a most elaborate and deliberate toilet, dressing every feather with care, and spending a half hour over the operation. All this time the invader stood on the top perch, backed against the wires, his long tail on one side like the train of a lady's dress, invincible determination in his manner. The calm indifference of the house-owner evidently did not please him, and the long drawn-out toilet was irritating; he grew thirsty, and dropped to the floor to drink, when the thrush remonstrated by a low, rapid "chook, chook, chook," and the mocking-bird made an impatient dive at him. This silenced but apparently did not hurt the bird, who stayed as long as he chose, and then quietly came out. From that moment the usurper claimed the cage, and the amiable owner easily contented himself with the one the other had deserted. When the mocking-bird had thoroughly established himself in every right and privilege he chose to consider his own, I hoped there would be peace, but I had not sounded the depths in his character; he began to tease. Not content with complete victory, life seemed dull without some object to worry. I really think it was his amusement; he certainly went at it as if it were. I noticed him one morning, standing on the ladder before his door, apparently working himself up to something. He first looked at me,--I had a book, and pretended not to see him,--then at the thrush, who was on the floor as usual; he jerked his body this way and that, puffed out his feathers, especially on the throat and breast, held his tail on one side and turned upward at an angle of forty-five degrees, which gave him a wicked expression. He looked full of life to the tips of his toes, and greatly excited. The other birds observed him; the Mexican in his cage rustled his wings, jerked his body, and at last gave his usual cry. Even the little goldfinch was impressed and looked on with interest.
