A 13-year study has found that the salmonella infection can build up on feeders and then spread among birds.
The study revealed that greenfinches and house sparrows appeared to be particularly vulnerable to the disease.
Bird lovers are being advised to disinfect feeders regularly to minimise the risk of infection.
