A race against time is underway to tackle a potential bird flu outbreak among swans in the Thames Valley. This urgent situation has sparked a collaborative effort between concerned citizens and dedicated charity volunteers.
The Animal and Plant Health Agency (APHA), sponsored by the Department for Environment, Food and Rural Affairs (Defra), has recorded a concerning rise in bird flu cases among swans since October. With 324 cases reported so far, including 39 in the first month of 2026 alone, the outbreak is showing no signs of slowing down.
However, there are fears that the official figures may not reflect the true extent of the crisis. Swan Support, an animal charity, has reported finding 46 dead swans in the Windsor and Maidenhead area since mid-January, along with an additional 26 in Newbury. This suggests a much higher mortality rate than initially thought.
"The situation is dire," says Wendy Hermon, Operations Director at Swan Support. "We've witnessed swans exhibiting unusual behavior, such as spinning in circles and bleeding from their eyes. These symptoms, coupled with lethargy, strongly indicate bird flu as the culprit."
The charity has sent some of the recovered swan bodies to Defra for testing, but confirmation of bird flu as the cause of death is still pending.
The highly infectious H5N1 strain of bird flu has wreaked havoc on bird populations across the UK since 2021. Scientists warn that a single infected bird can transmit the virus to up to 100 others, and it can be spread through feces, mucus, blood, and saliva.
David Barber, the King's Swan Marker, who monitors swan populations, describes the situation as "one of the worst years we've had for bird flu." He estimates that over 40 swans have died in the Thames Valley region, but the actual number could be twice as high.
"We're all certain it's bird flu," Barber adds, expressing frustration at the lack of official confirmation from Defra.
Hermon commends the public for their proactive role in reporting suspected cases to Swan Support. The charity has been instrumental in collecting affected birds and removing them from waterways to prevent further spread.
"Without the public's help, the virus would likely have a much wider impact on other bird species," she emphasizes.
An APHA spokesperson has acknowledged the reported wild bird deaths in the Berkshire area and confirmed that several swans have tested positive for highly pathogenic avian influenza. The spokesperson advises the public to avoid touching dead or visibly sick birds and to practice good hand hygiene after any contact with wild bird feces, feathers, or during bird feeding.
Swan Support echoes these guidelines and encourages anyone who finds dead wild birds to report their findings online or contact Defra's helpline.
