Rise in Swan Numbers on the River Thames
After a concerning decline, the population of swans on the River Thames has started to show signs of recovery, according to the latest annual survey. The traditional five-day event known as swan upping recorded 115 young swans this year, compared to just 86 in 2024. This marks a positive shift in the numbers of these iconic birds, which have faced challenges in recent years.
The drop in swan numbers has been attributed to several factors, including avian flu and instances of human cruelty. However, the latest data from the King’s swan marker, David Barber, indicates that the sharp decline observed over the past two years has begun to reverse. Despite this improvement, the current numbers are still lower than the 155 swans counted in 2022.
Mr. Barber expressed optimism about the results, stating that the situation has improved compared to last year. He noted that the bird flu, which had affected the swan population for several years, appears to be less prevalent on the Thames now. “Last year was the lowest number we’ve had for years and years and years, with only 86 cygnets across the entire count,” he said.
Swan upping is an important annual event that involves counting the swan population, checking the health of the young cygnets, and ensuring that their numbers remain stable. The process involves a five-day journey upstream along the River Thames to Abingdon Bridge in Oxfordshire, using traditional rowing skiffs. This practice dates back to the 12th century when the Crown claimed ownership of all unmarked mute swans in Britain to ensure a supply for royal feasts.
Today, the focus of swan upping has shifted towards conservation and education. Local primary school children are invited to participate in Q&A sessions throughout the week, learning about the importance of protecting these graceful birds. Mr. Barber emphasizes the need to discourage young people from mistreating swans, highlighting recent incidents where individuals have used catapults and air guns to harm the birds.
The event has also become a popular attraction, drawing crowds along the banks of the River Thames. People gather to witness the traditional ceremony and learn more about the history and significance of swan upping. As the swan population continues to recover, the event serves as a reminder of the importance of preserving wildlife and maintaining a balance between nature and human activity.
With ongoing efforts to protect the swans and raise awareness about their plight, there is hope that the numbers will continue to rise in the coming years. The success of this year’s survey is a positive sign, but continued vigilance and community involvement will be essential to ensure the long-term survival of these beloved birds on the River Thames.
