If you happened to be near the Thames River in Southern England from July 19th to the 23rd, you may have witnessed a rather unusual event - Swan Upping, an annual census of swans commissioned by the order of her Majesty, Queen Elizabeth II.

The count was led by the Queen's chief Swan Marker, David Barber, whose main job is to ensure that England's swan population is maintained. Assisting him in this rather tricky chore, is Swan Warden, professor, Christopher Perrins from Oxford University and a number of part-time Swan Uppers, who ride aboard skiffs (small boats), dressed in traditional scarlet and white uniforms.

The team's main task is to row up the Thames for five days, counting, weighing and measuring the swans and cygnets (baby swans), as well as, checking them for diseases and injuries.

While this whole thing may sound a little strange, Swan Upping is an important royal tradition that dates all the way back to the 12th century, and stems from the premise (which still holds true today) that all unmarked swans swimming in the open waters, belong to the Royal family. In the past, the Swan Markers also captured a few to be served as a tasty feast for banquets. Now, it is more about conserving the swans, educating people and also attractng tourists.

Also now the Royal family lays claim to only the swans that are swimming on the Thames and its tributaries - However, we do wonder if the swans of the 21st Century are as obedient and show up for the summons to be counted !
