Since the introduction of new regulations in 1997, the number of zebra crossings and Belisha beacons has fallen in the northern counties of England, being replaced by pelican crossings or puffin crossings, with pedestrian-controlled traffic signals; a waiting pedestrian can stop vehicular traffic by pressing a button and waiting for the pedestrian signal of a red and green man to change to green. The green man can be accompanied by a green bicycle to indicate that the crossing is designated for pedestrians and cyclists; continuing the bird-name theme, this type of crossing is called a toucan crossing, as in, 'two can' cross. Another variation is the pegasus crossing where the pedestrian is accompanied by a green horse to indicate that the crossing is designated for pedestrians and horses, for example, at Hyde Park Corner, London.
