Royals The Queen's Swans May Have Been Killed by Bird Flu Outbreak at Harry and Meghan's Wedding Site More than 20 of Queen Elizabeth's swans from her Windsor flock have died amid fears that they succumbed to a bird flu outbreak sweeping the area By Erin Hill Erin Hill Twitter Senior News Editor, PEOPLE People Editorial Guidelines Published on February 5, 2018 12:09 PM Share Tweet Pin Email More than 20 of Queen Elizabeth’s swans from her Windsor flock have died amid fears that they succumbed to a bird flu outbreak sweeping the area. Scientists from the Department for Environment, Food and Rural Affairs (Defra) are currently investigating the suspected case of H5N6 avian influenza, according to reports. David Barber, the Queen’s official Swan Marker, who is responsible for the 800-year tradition of carrying out an annual census of Thames swans, said in a statement: “Over 20 swans have died now and there’s a lot which are seriously ill which will die — well over 20 more.” Defra confirmed that seven of the swans that died were currently being tested for bird flu. “We are deeply saddened by the loss of these swans,” Barber continued. “We’re waiting to hear from Defra, but yes it is bird flu. I’m sure the Queen would be concerned. You cannot do anything about it. It will burn itself out. They’re wild birds and it is spread by wild birds and we’ve been very unlucky.” Queen attends annual Swan Upping in 2009.

The Queen, who is a known animal lover, takes great interest in the Windsor swans. The Crown owns all mute swans (the most common of three local species) found on open water in the U.K. as part of a tradition dating back to the 12th century. Each year, a Swan Upping takes places in which the animals are weighed and measured. Queen attends annual Swan Upping in 2009.

The swans are then set free again.” After the Swan Upping has been completed every July, the Queen’s Swan Marker releases a report that provides data about the number of all swans that were accounted for.
