CONCERNS have been raised over a "nasty" strain of bird flu that is killing flocks worth of swans and other birds.

WeCare Wildlife Rescue Centre in Brantham has spotted dead swans at The Walls, Mistley, and advised residents on what to do if a dead bird is encountered.

After reporting a low amount of cases at the start of the year, a new strain has caused deaths to rise quickly in recent weeks.

Gill Lewis, who runs WeCare Wildlife Rescue Centre, said: “There is a very nasty bird flu strain around, it’s heartbreaking as in some areas whole flocks have died.

“We have worked very hard to feed extra, good quality food and our feeders have been careful while feeding.

“Caring for sick and injured swans or other birds has been challenging as we have to take care not to spread the disease.”

Vets are limited with what they can do in terms of care and a lot of sanctuaries cannot take sick swans in, which has led WeCare to work even harder at The Walls

The WeCare team has cared for and rehabilitated a lot of birds this year but can only do so much as they are unable to handle dead animals.

Gill added: “Defra advise not to handle birds and if we did and brought avian flu back to the rescue all our animals on site would be culled.

“The whole situation is devastating and stressful, as volunteers we are doing everything possible within Defra guidelines.”

WeCare has advised residents who come across a bird whose death looks suspicious to leave it alone and report the incident to Defra and if on public land, environmental services at Tendring Council.

It is the responsibility of those bodies to dispose of the birds and WeCare cannot and is not allowed to do so.

A spokesman for Defra said: “If you suspect bird flu in poultry or other captive birds, you must report it immediately by calling.

“Bird flu is a notifiable in poultry and other captive birds. If you do not report it, you’re breaking the law.”
