THE FOLLOWING STATEMENT IS ISSUED BY THE PRESS SECRETARY TO THE QUEEN

Swan Upping, the annual census of the swan population on certain stretches of the River Thames, was announced today by David Barber, The Queen's Swan Marker. Swan Upping will start on Monday 15th July from Sunbury-on-Thames and finish in Abingdon, Oxfordshire on Friday 19th July.

The ceremony of Swan Upping dates from the twelfth century and takes place during the third week of July each year. It has always been the duty of the Sovereign's Swan Marker to count the young cygnets each year and to ensure that the swan population is maintained. With the assistance of the Swan Warden, Professor Christopher Perrins of the University of Oxford, the swans are also given a health check.

Announcing the dates for Swan Upping, David Barber said:

"There has been a significant increase in the number of breeding pairs nesting this year, with cygnets hatching earlier than usual. Fortunately the swans have avoided the spring floods that have washed away many nests in previous years.

"Vandalism has once again taken its toll on the swan population as nests have been destroyed and eggs broken. These incidents occur mainly where the swans have nested in unsuitable locations within easy reach of riverside towns.

"Fishing hooks and line are a significant factor in the injuries and deaths of many young cygnets. Discarded fishing tackle poses a severe threat of drowning and ingested hooks and line cause immense suffering which often results in death.

"The dedication and vigilance shown by swan rescue organisations, combined with the support of the public and the work of the Environment Agency, is helping to maintain swan numbers.

"Conservation continues to play a vital role in the ceremony of Swan Upping. It collates important data that reflects the enormous changes in the river's environment over past years, and a greater awareness of methods of conservation has resulted in a higher level of protection for the swans.

"Education will play an important role in Royal Swan Upping this year and several schools will be visiting the banks of the River Thames. This educational programme will give young children an insight into how to protect the welfare of the swans.

"Children from local schools will accompany the Swan Uppers as they carry out the swan census and health checks. They will have the opportunity to learn the history of Swan Upping and to understand the conservational impact of the ceremony today. I hope this will increase their awareness of the value of our wildlife and import a sense of the respect with which it should be treated."
