VIDEO: Army of volunteers help with swan census

Around 200 volunteers, up to half paddling kayaks and canoes, have been draftedin to assist with the biennial round-up of swans at Abbotsbury Swannery on Saturday.

The round-up hopes to take a snapshot of the size and health of the swan population on the Fleet Lagoon at Chesil Beach - the world’s only managed colony of mute swans.

The swans are individually checked by vets, vaccinated, ringed, weighed and measured.

"Swanherd" Dave Wheeler said: "It is an amazing sight. We estimate there are around 700 swans on the Fleet at the moment, as well as 130 cygnets in the swannery itself.

"Visitors will still be able to watch and help feed the swans at 12 noon and 4pm."
