Poultry farmers are being warned to keep birds indoors as a precaution against a deadly bird flu strain in mainland Europe.
The Scottish Government has declared an avian influenza prevention zone requiring that all poultry and captive birds are kept separate from wild birds.
For England, government chief vet Nigel Gibbens has declared a "prevention zone", with requirements for commercial and individual poultry and captive bird keepers to keep their birds inside, or take steps to separate them from wild birds.
It comes amid reports of a highly pathogenic strain of H5N8 avian influenza causing high mortality in wild birds in mainland Europe, mostly affecting waterfowl.
There have been no cases of this strain detected in the UK.
No cases have yet been identified in the UK and the prevention zone applies to all of Scotland and will remain in place for 30 days. Similar measures have also been declared in England.
In January, about 40,000 birds were culled at a farm near Dunfermline, Fife, after a case of H5N1 avian influenza was identified among chickens.
Food and health experts said the current threat to the public is "very low" and there is no danger in consuming eggs or poultry.
