Although thus immobile and silent, the grosbeak was far from being stupid. He had decided opinions and tastes as well defined as anybody's. For example, when he came to me his cage stood on a shelf next to that occupied by two orchard orioles, and he was never pleased with the position. He was hardly restless even there, while suffering what he plainly considered a grievance, but he was uneasy. I saw that something was wrong, and guessed at once that it was because his upper perch was three inches lower than that in the next cage, and to have a neighbor higher than himself is always an offense to a bird. As soon as I raised his cage he was satisfied on that score, and no more disturbed me in the early morning by shuffling about on his perch and trying to fly upward. But still things were not quite to his mind, and he showed it by constantly going into the cage of the orioles and settling himself evidently with the desire of taking up his residence there. He was so gentle and unobtrusive everywhere, that no one resented his presence in the cage, and he could have lived in peace with almost any bird. But I wanted him contented at home, and moreover, I was curious to find out what was amiss, so I tried the experiment of removing his cage from its position next to the lively orioles, and hanging it alone between two windows, where, although not so light, it had the advantage of solitude. The change completed the happiness of the grosbeak. From that day he no more intruded upon others, but went and came freely and joyously to his own cage, and from being hard to catch at night he became one of the most easy, proceeding the moment he entered his home toward dark to the upper perch to wait for me to close the door before going to his seed-dish. In fact, he grew so contented that he cared little to come out, and often sat in his favorite corner of the cage by the hour, with the door wide open and the other birds flying around. Now, too, he began to sing in a sweet voice a very low and tender minor strain. Among his other peculiarities this bird scarcely ever seemed to feel the need of utterance of any soft. On the rare occasions of any excitement he delivered a sharp, metallic "click"; a sudden alarm, like the attack of another bird, called out a war-cry loud and shrill, and very odd; and in the contest over the important question of precedence at the bath he sometimes uttered a droll squeal or whining sound. Besides these, he made singular noises in bathing and dressing his feathers, which are not uncommon among birds, but are difficult to describe. They always remind me of the rubbing of machinery in need of oil.
