The Mocking-Bird (_Turdus polyglottus_) is well known in the Middle and Southern States, but seldom passes a season in New England, except in the southern part of Rhode Island and Connecticut, which seem to be the northern limit of its migrations. Probably, like the Rose-breasted Grosbeak, which is constantly extending its limits in an eastern direction, the Mocking-Bird may be gradually making progress northwardly, so that fifty years hence both of these birds may be common in Massachusetts. The Mocking-Bird is familiar in his habits, frequenting gardens and orchards, and perching on the roofs of houses when singing, like the common Robin. Like the Robin, too, who sings at all hours excepting those of darkness, he is a persevering songster, and seems to be inspired by living in the vicinity of man. In his manners, however, he bears more resemblance to the Red Thrush, being distinguished by his vivacity, and the courage with which he repels the attacks of his enemies. The Mocking-Bird is celebrated throughout the world for his musical powers; but it is difficult to ascertain precisely the character and quality of his original notes. Hence some naturalists have contended that he has no song of his own, but confines himself to imitations. That this is an error, all persons who have listened to him in his native wild-wood can testify. I should say, from my own observations, not only that he has a distinct song, peculiarly his own, but that his imitations are far from being equal to his original notes. Yet it is seldom we hear him except when he is engaged in mimicry. In his native woods, and especially at an early hour in the morning, when he is not provoked to imitation by the voices of other birds and animals, he sometimes pours forth his own wild notes with full fervor. Yet I have often listened vainly for hours to hear him utter anything but a few idle repetitions of monotonous sounds, interspersed with some ludicrous varieties. Why he should neglect his own pleasing notes, to tease the listener with his imitations of all imaginable discords, is not easily explained.
