The Department for the Environment, Food and Rural Affairs (Defra) plans to kill the 100-150 monk parakeets who live in the wild in Hertfordshire. Two years ago, Natural England added both the monk parakeet and the ring-necked parakeet to the General Licence, which means the birds can be shot without prior permission being obtained, as long as certain criteria were met. But now Defra plans to eradicate all monk parakeets saying they could pose a danger to crops, electricity pylons and other species. The RSPB backs the cull.
