People swam in a wildlife pond on Hampstead Heath during a heatwave, disturbing nesting swans and other birds. Conservationists and the City of London said the scene threatened wildlife and broke pond rules.
A pond on Hampstead Heath is home to baby swans and other birds. When many people jumped in to cool off during hot weather, the birds were scared and their nests were disturbed.
That matters because baby birds need quiet, safe water and nearby food. If parent birds leave their nests, the eggs or chicks can be in danger, like leaving a sleeping baby alone in a noisy room.
The people in charge said the pond is not for swimming and that visitors should use safe swimming places instead. The problem is not just about people having fun; it is also about keeping the birds alive.
Analysis
What happened
During London’s record 35C May heat, dozens of people entered a pond on Hampstead Heath that is meant as a wildlife conservation area. The pond contains nests, eggs, and young birds, including swans with 12-day-old cygnets.
Why conservationists objected
Nature groups said the timing was especially sensitive because it is peak nesting season for water birds. According to the RSPB, disturbance can cause adult birds to abandon nests, leaving eggs and chicks exposed to predators or starvation. The organization urged swimmers to use authorised, lifeguarded places instead of nature reserves.
The Instagram account Swans of Hampstead Heath said the birds were being squeezed into a small part of the pond, making it harder for them to reach natural food. In one video described by the Guardian, a swan appeared to prod an unhatched egg that had fallen into the water during the disturbance.
Official response
The City of London called the conduct “utterly appalling” and said swimming in non-lifeguarded ponds is dangerous, against bylaws, and harmful to habitats. Alderman Gregory Jones KC said enforcement could include fines or arrests if needed.
Wider context
A campaigner quoted in the piece argued that the problem reflects a shortage of accessible outdoor swimming space in London, especially after the loss of lidos and pollution in rivers. The article also notes a safety warning: open water can be much colder than the air, raising the risk of cold water shock and drowning.
