By prerogative right, the British Crown enjoys ownership of all unmarked mute swans in open water. Rights over swans may, however, be granted to a British subject by the Crown (accordingly they may also be claimed by prescription).[1] Until the 16th century, the ownership of swans in a given body of water was commonly granted to landowners. The only bodies who still exercise such rights are two livery companies of the City of London, the Worshipful Company of Vintners and the Worshipful Company of Dyers, who thus share equally with the Crown in the number of swans in the Thames that they own. The tradition of swan upping on the Thames began in the 12th century.[2][3]
Swan upping is the traditional means by which the swans on the Thames are apportioned among the three proprietors. Its main practical purposes today are to conduct a census of swans and check their health. It occurs annually in the third week of July. Over five days, the Crown's, the Vintners' and the Dyers' respective 'swan uppers' row up the river in skiffs (in recent centuries from Sunbury to Abingdon).[4][5][6]
The Crown's swans are recorded by the Marker of the Swans, who is rowed in a skiff by oarsmen from the Company of Watermen and Lightermen.[7] The Crown's swan uppers, who wear distinctive red uniforms, catch the swans, weigh and measure the cygnets, and check them for injuries.[4][8][9]
Cygnets are determined to belong to the Crown, the Dyers or the Vintners based on their parentage.[4] Swans belonging to the Crown are left unmarked, except for a lightweight ring linked to the database of the British Trust for Ornithology.[citation needed] Those belonging to the Dyers and Vintners receive a similar ring on the other leg.[citation needed] The rings have replaced nicks on the swans' bills, which used to be made with a metal implement, one nick for the Dyers and one on each side for the Vintners.[9] The former practice is reflected in the The Swan with Two Necks, the name of a former pub in the City connected with the Vintners, which was a corruption of "The Swan with Two Nicks".[citation needed]
On 20 July 2009, Queen Elizabeth II, as "Seigneur of the Swans", attended the Swan Upping ceremony, the first time a reigning monarch had done so.[9]
In 2012, exceptional high river flows for summer prompted a partial cancellation: between Sunbury and Windsor, the first time the tradition is known to have been cancelled (albeit partially).[3]
The first known full cancellation took place in 2020 due to COVID-19 social distancing measures.[10]
