Swan upping, the queen's tradition of protecting swans on the thames

The video discusses the tradition of Swan Upping in the UK, where all swans belong to the Queen, particularly on the River Thames. David Barber, responsible for the Queen's swans, conducts an annual census called Swan Upping. This involves a 79-mile journey in rowing skiffs to weigh, measure, and check swans for injuries before releasing them. The tradition dates back to the 12th century when swans were a food source. Today, they are protected, and the event focuses on conservation. The Queen has participated in the past, and the video concludes with a toast to her.
