The traditional annual census of swans, known as "swan upping," has reported a significant decline in the number of cygnets on the River Thames compared to the previous year. The survey,

overseen by the King's swan marker, David Barber, revealed a 40% drop in cygnet numbers, with only 94 found during the five-day search along the Thames, from London to Abingdon in Oxfordshire.

The decrease has been attributed to avian flu, which has had a devastating impact on the swan population, along with other factors like violence against the birds. Incidents of shootings, catapult attacks, and dogs killing swans have raised concerns about their safety and well-being. Mr. Barber expressed disappointment in the results but noted that given the threat of avian flu, the decline was somewhat expected.

The total count of cygnets found this year is the lowest in seven years, dropping from 155 in 2022. Despite the decline, Mr. Barber stated that the cygnets that were found appeared to be in good condition.

High flood-water washing away nests also played a role in the decline. Additionally, acts of vandalism, including shooting swans with air rifles and other weapons, destroying eggs and nests, and harming swans with dogs off leads, have contributed to the challenges faced by the swan population.

"Swan upping" is an age-old tradition that began in the 12th century when the Crown sought to protect its ownership of swans. Today, the event has evolved into an effort for wildlife conservation. Teams, dressed in scarlet outfits, row up the river, stopping to count, weigh, and measure any cygnets they encounter. Swans, once considered a delicacy in medieval banquets, are now a protected species, and the "swan upping" exercise aims to monitor and safeguard their well-being. Photo by Arthena, Wikimedia commons.
