CLAP-NET, in birding, a sort of net contrived for the taking of larks with the looking-glass, by the method called daring or doring. The nets are spread over an even piece of ground, and the larks are invited to the place by other larks fastened down, and by a looking-glass composed of five pieces, and fixed in a frame so that it is turned round very swiftly backwards and forwards, by means of a cord pulled by a person at a considerable distance behind a hedge. See DORING.
