MR. SWEET'S ACCOUNT OF THE WHITE-THROAT. This is one of the most delightful and pleasing birds that can be imagined. If kept in a large cage with other birds it is so full of antics, in flying and frisking about, and erecting its crest, generally singing all the time, certainly nothing can be more amusing. It is also quite as hardy as the blackcap, and if a good one be procured, it is little inferior in song: but in this they vary considerably, the wild ones as well as those in a cage. I have now one in my possession that I have had about eleven years, in as good health, and singing as well as ever; and certainly no song need be louder, sweeter, or more varied. It is of the same temper as a nightingale, never suffering itself to be outdone. It will indeed sing for hours together against a nightingale, now in the beginning of January, and it will not suffer itself to be outdone; when the nightingale raises its voice, it also does the same, and tries its utmost to get above it; sometimes in the midst of its song it will run up to the nightingale, and stretch out its neck as if in defiance, and whistle as loud as it can, staring it in the face; if the nightingale attempts to peck it, away it is in an instant flying round the aviary, and singing all the time. In a wild state, the present species is generally to be found in hedges and gardens, and is the most common of our British warblers, visiting us the beginning or middle of April, and leaving us towards the end of September; sometimes a solitary one may be seen in October, but not frequently. It is particularly fond of flies, or a rose-branch covered with aphides will please it very much. THE BABILLARD. Sylvia curruca, BECHSTEIN; Motacilla dumetorum, LINNÆUS; La Fauvette babillarde, BUFFON; Das Müllerchen, BECHSTEIN. This bird somewhat resembles the white-throat, but is smaller, and has less rust colour on the wings. It is five inches long, the tail measuring more than two. The beak is five lines in length, very pointed, black above, and bluish below; the iris has two rings, the outer one pale yellow, the inner a brilliant golden yellow; the shanks, seven lines high, are raven black; the head and rump are dark ash grey; the rest of the upper part of the body is grey, with a reddish tint; the cheeks and the part behind the ears are darker than the head; the throat and under part of the body are white, but the sides of the breast are tinged with reddish grey, and those of the belly with reddish brown. The birds must be before you to be able to distinguish the two sexes; you can then only perceive that the head of the female is of a lighter colour, and the feet rather blue than black.
