Bird feeding's 'health warning'

Help

Wild birds can suffer if humans feed them too much unhealthy food according to wildlife charities.

The RSPB and Wildfowl and Wetlands Trust are warning the public to think what they put out for the birds over the winter period because too much white bread and starchy food is not good for them.

Radio Wales' Felicity Evans asked Dr Alex Pollard from RSPB Cymru what it wrong with white bread for birds.
