This is the third case of bird flu to be confirmed in the UK this week, with the virus being found in both flocks of pheasants and turkeys earlier this week.
A fourth case of avian influenza (bird flu) was confirmed in Ireland this week.
The case was identified in a whooper swan around the Leitrim/Longford border. It is the second case to be identified in a whooper swan in Ireland.
Last week, the Department of Agriculture confirmed a third case of bird flu in a whooper swan in the Borrisokane area of Tipperary.
The two other cases of the disease were found in wigeons, one in Wexford and one in Galway.
The Department has warned poultry owners and those with backyard flocks to confine their birds, even if they only keep a few chickens.
