Mike Roberts is the falconer at Great Hall of Peckforton Castle in Cheshire who has trained Ollie the barn owl to deliver the rings to the best man the moment the registrar asks for the rings. The owl has been taught to respond to Roberts' whistle and fly down from minister's gallery to the best man who will be wearing a falconry glove. The best man then will be able to remove the velvet pouch containing rings from the owl's leg. If you are interested in inviting Ollie to your wedding, contact Roberts here for a training session. They have trained eagles too.
