Swimmers urged to keep out of Hampstead Heath pond to protect nesting swans

Nature groups say cygnets and their parents need to be left alone by people trying to stay cool in heatwave

Nature groups have pleaded with swimmers to give wildlife a wide berth after dozens of people swam in a nature pond on Hampstead Heath among nests of baby birds.

Swans and their 12-day-old cygnets were disturbed by hordes of splashing revellers in the north London park on Monday as London reached record 35C temperatures. In one video, a swan was seen poking an unhatched egg with its beak after it fell into the water during the chaos.
