In a rather unusual experiment llamas have been brought in to protect birds at a RSPB reserve. The reserve has problems with predators such as foxes taking the birds eggs and chicks. It is hoped that the llamas will act as guards during the nesting season. Llamas are known to be highly territorial and are already used as livestock guards in some areas. The Prince of Wales for example uses alpacas to protect lambs from foxes during the lambing season on his farm at Highgrove.
