Since the 12th century, British rulers have claimed ownership of mute swans on open waters. That’s how the title Seigneur of the Swans came into being. Historically a luxury for lavish feasts, the practice evolved into a conservation ceremony over centuries.
Modern-Day Swan Upping
Each July, a flotilla of wooden skiffs sets off from Sunbury up the Thames to Abingdon. Led by the King’s Swan Marker, David Barber for over 30 years, roving teams from the Crown, and the historic Vintners and Dyers livery companies, row in distinctive scarlet, white and blue uniforms.
They raise a cry of “All up!”, surround swan families, and gently lift cygnets and adults ashore for health exams. This includes weighing, measuring, ringing and checking for injuries or disease. The ceremony spans about 80 miles over five days, providing vital data on population trends and bird health.
Health Insights & Conservation
Last year’s census saw only 86 young cygnets, down 45%, after a severe avian flu outbreak. This year began with 16 cygnets on day one, offering a hopeful sign amid ongoing concerns about pollution, wildlife cruelty, and disease.
It’s More Than Tradition
What began as a display of royal privilege has matured into a hands‑on environmental practice. The swan marker doesn’t just conduct the census, he advises fishing groups, coordinates rescues, and collaborates with organisations on swan welfare. Educational outreach, including Q&As with schoolchildren, forms a key part of the programme.
