A Berkshire charity say they're concerned bird flu is effecting swans on the Thames and River Kennet.
Swan support - a charity based in Maidenhead - say dozens of swans have died in Newbury, Maidenhead and Windsor.
The charity says many swans are showing symptoms and they've sent samples to government laboratories for testing.
Symptoms for the most serious form of bird flu include swollen head, runny eyes and breathing difficulties.
