Orphaned Birds Taught To Sing

RSPCA centres are teaching orphaned baby birds how to sing, using CDs (of birds singing). It is very important for male birds to be able to sing, as they need to be able to do this to defend territory and find a mate. It is not clear whether the RSPCA's programme may accidentally teach female baby birds how to sing, leading to an outbreak of bird feminism.
