 The field may be divided into two groups, with one group, the "First Field," that takes a more direct but demanding route that involves jumps over obstacles while another group, the "Second Field" (also called "Hilltoppers" or "Gaters"), takes longer but less challenging routes that utilise gates or other types of access on the flat.In the United Kingdom, since the introduction of the hunting ban, a number of hunts have employed falconers to bring birds of prey to the hunt, due to the exemption in the Hunting Act for falconry.Many experts, such as the Hawk Board, deny that any bird of prey can reasonably be used in the British countryside to kill a fox which has been flushed by (and is being chased by) a pack of hounds.
