Reference has already been made to the now obsolete use of nets for the capture of these birds when "roding." The cock-shuts, as they were called, were spread so as to do their work after sundown, and this is the meaning of Shakespeare's allusion to "cock-shut time." This "roding" is a curious performance on the part of the males only, and it bears some analogy to the "drumming" of snipe. It is accompanied indeed by the same vibrating noise, which may be produced from the throat as well, but is more probably made only by the beating of the wings. There appears to be some divergence of opinion as to its origin in both birds, though in that of the snipe such sound authorities as Messrs. Abel Chapman and Harting are convinced that it proceeds from the quivering of the primaries, as the large quill-feathers of the wings are called. Other naturalists, however, have preferred to associate it with the spreading tail-feathers. Whether these eccentric gymnastics are performed as displays, with a view to impressing admiring females, or whether they are merely the result of excitement at the pairing season cannot be determined. It is safe to assume that they aim at one or other of these objects, and further no one can go with any certainty. The word "roding" is spelt "roading" by Newton, who thus gives the preference to the Anglo-Saxon description of the aerial tracks followed by the bird, over the alternative derivation from the French "roder," which means to wander. The flight is at any rate wholly different from that to which the sportsman is accustomed when one of these birds is flushed in covert. In the latter case, either instinct or experience seems to have taught it extraordinary tricks of zigzag man[oe]uvring that not seldom save its life from a long line of over-anxious guns; though out in the open, where it generally flies in a straight line for the nearest covert, few birds of its size are easier to bring down. Fortunately, we do not in England shoot the bird in springtime, the season of "roding," but the practice is in vogue in the evening twilight in every Continental country, and large bags are made in this fashion.
