The areas deemed most at risk of triggering an outbreak are beaches, estuaries and other wetlands where gulls,
geese,
swans,
ducks and waders gather in large numbers and which are near poultry farms.
Britain has stepped up its defences against the deadly strain of avian flu and plans to increase surveillance at the most likely disease hotspots.
Debby Reynolds, the Chief Veterinary Officer, has ordered intensive sampling of birds in priority areas, including the East of England coast, Morecambe Bay and the Solway Firth in the North West, the eastern coast of Scotland and the South Coast.
Teams of wildlife experts are being enlisted for the testing programme. Live birds will be tested and then released, and dead birds found in hotspots and birds shot for sport or pest control will also be examined.
