In the suburbs of London there are many persons, who, during the months of October and March, get their livelihood by an ingenious, and we may add, a scientific, method of bird-catching, which is totally unknown to other parts of Great Britain. The reason of this trade being confined to so small a compass, arises from there being no considerable sale for singing birds except in the metropolis; and as the apparatus for their purpose is heavy, and must be carried on a man’s back, it prevents the bird-catchers going to above three or four miles’ distance. This method of bird-catching must have been long practised, as it is brought to a most systematic perfection, and is attended with very considerable expense. The nets are a most ingenious piece of mechanism, are generally twelve yards and a half long, and two and a half wide; and no one, till he becomes eye-witness of the puller’s success, would imagine that a bird, which is so very quick in all its motions, could be caught by the nets flapping over each other. The wild birds fly, as the bird-catchers term it, chiefly during the month of October, and part of September and November, as the flight in March is much less considerable than that of Michaelmas. The several species of birds do not make their appearance precisely at the same time during the months of September, October, and November. The pipet, a small species of lark, but inferior to the others in singing, for example, begins to fly about Michaelmas, and then the woodlark, linnet, goldfinch, chaffinch, greenfinch, and other birds of flight, succeed; all of which are not easily caught, or in any numbers at any other time, and more particularly the pipet and the woodlark. These birds, during the Michaelmas and March flights, are chiefly on the wing from day-break to noon, though there is afterwards a small flight from two till night, but this is so inconsiderable, that the bird-catchers take up their nets at noon. It well deserves the attention of the naturalist whence these periodical flights of certain birds arise. As the ground, however, is ploughed during the months of October and March for sowing the winter and spring corn, it should seem that they are thus supplied with a profusion both of seeds and insects, which they cannot so easily procure at any other season. It has been observed, too, that, during their sitting, they fly always against the wind; hence, there is great contention amongst the bird-catchers, who shall gain that point. If, for example, it is westerly, the bird-catcher who lays his nets most to the east, is sure almost of catching every thing, provided his call birds are good; a gentle wind to the south-west generally produces the best sport. The bird-catcher generally carries with him five or six linnets, of which more are caught than any other singing-bird, two goldfinches, two greenfinches, one woodlark, one redpole, a yellow hammer, titlark and aberdevine, and perhaps a
