short jerks, which, when the birds are good, may be heard at a great distance. The ascendancy by this call is so great, that the wildest bird is stopped in his flight; and, if not a sharper, as the bird-catchers style a bird acquainted with the nets, lights boldly within twenty yards perhaps of three or four bird-catchers, on a spot which, otherwise, it would not have taken the least notice of. Nay, it frequently happens, that if only half a flock are caught, the remainder will immediately after light in the nets, and share the same fate, and should only one bird escape, that bird will suffer itself to be pulled at till it is caught, such a fascinating power have these call-birds. Here it is worth mentioning, that the bird-catchers frequently lay considerable wagers whose call-bird can jerk the longest, as that determines the superiority. They place them opposite to each other, by an inch of candle, and the bird who jerks the oftenest before the candle is burnt out, wins the wager. There have been instances of a bird giving 170 jerks in a quarter of an hour; and of a linnet, in such a trial, persevering in its emulation till it swooned from the perch. Birds, when near each other, and in sight, seldom jerk or sing. They either fight, or use short and wheedling calls; the jerking of these call-birds, therefore, face to face, is a most extraordinary instance of contention for superiority in song. Various methods are used to catch different kinds of birds. The bullfinch, though not properly a singing bird, or a bird of flight, as it does not move farther than from hedge to hedge, yet, as it sells well on account of its learning to whistle tunes, and sometimes flies over where the nets are laid, the bird-catchers have often a call-bird to ensnare it, though most of them can imitate the call with their mouths. It is remarkable that the female bullfinch answers the purpose of a call-bird as well as the male, which is not experienced in any other species of bird taken by the London bird-catchers. The nightingale is not a bird of flight, in the sense in which the bird-catchers use the term. Like the robin, wren, and many other singing birds, it only moves from hedge to hedge, and does not take the periodical flights in October and March. Those who catch these birds make use of small trap-nets, without call-birds, and are considered as inferior in dignity to other bird-catchers, who will not rank with them. The arrival of the nightingale is expected by the trappers in the neighbourhood of London, the first week in April; at the beginning, none but cocks are taken, but in a few days the hens make their appearance, generally by themselves, though sometimes with a few males. The latter are distinguished from the females, not only by their superior size, but by a great swelling of their vent, which commences on the first arrival of the hens. They are caught in a net-trap, the bottom of which is surrounded with an iron
