The song of the nightingale is peculiarly mellow and plaintive; and its compass, such as to reach through three octaves, and sometimes even more. In sprightliness it yields to the notes of the sky-lark, the linnet, goldfinch, and even the redbreast. A nightingale in singing its whole song was remarked to have sixteen different beginnings and closes; at the same time that the intermediate notes were generally varied in their succession with so much judgment, as to produce a most pleasing variety. It is to be remarked, that nightingales in general do not, in a wild state, sing more than ten weeks in the year; whilst those in cages continue their song for nine or ten months. Notwithstanding the naturally beautiful song of these birds, they readily adopt the notes of any other. They will even modulate their voice to a given key, and that so readily, that if any person whistle a note to it, the nightingale will immediately try in its strain an unison with that note. Delightful as the song of the nightingale is, it is certain that some people have a dislike to it. We have even been told of a person who entertained so great an abhorrence for these birds as to have all the trees in his neighbourhood cut down, that, being thus without shelter, they might be driven away. It may perhaps be worth while to remark, in addition, that this person was delighted with the croaking of frogs. The food of nightingales consists principally of insects, small worms, and the grubs of ants. They usually build their nests near the ground, among briers, in some low tree by a hedge or bush, and have four or five eggs. 148. _The WHEAT-EAR, or WHITE-RUMP_ (Motacilla oenanthe), _is a bird about the size of a sparrow, distinguished by its back being of a hoary colour; the forehead, a line above the eyes, and the rump being white, and by having a black band through each eye._ _These birds are migratory, and found in the southern parts of England from about the beginning of May till the middle or end of September. They are also found on the continent of Europe, in Asia, and Africa._ On the downs of Sussex the number of wheat-ears is sometimes so great that more than eighty dozen have been caught by one person in a day. They become fat in the autumn, and are then much esteemed for the table. During a rainy season they are fatter than in a dry one; this is accounted for by their feeding not only on insects, but on earth-worms, which come out of the ground in much greater numbers during wet than in dry weather. These birds are caught, by the shepherds, in snares made of horse-hair, and placed beneath a long turf. Part of them are eaten in the neighbourhood, part are pickled and sent to London for sale, and many are potted. When eaten fresh, they are generally roasted, wrapped up in vine leaves.
