Swans and cygnets are caught, measured, assessed and tagged on the River Thames during Swan Upping on Monday in London. Swan Upping, the annual census of the River Thames’ swan population, is led by David Barber, The Queens Swan Marker. It begins on July 15 in Sunbury and ends at Abingdon, Oxfordshire, on July 19. The Queen’s Swan Marker and the accompanying Swan Uppers of the Vintners’ and Dyers’ Livery Companies use six traditional Thames rowing skiffs in their five-day journey upstream to ensure that the swan population is maintained.
