A national Avian Influenza Prevention Zone (AIPZ) came into force for the whole of England and Scotland at noon on Saturday.

All bird keepers, from people with pet birds to farmers with huge flocks, are now required to follow strict hygiene measures imposed by the government - and in some counties, birds must be kept indoors.

England and Scotland have been placed under mandatory prevention zones amid an alarming surge in cases of bird flu.

A strain of avian flu that has infected humans in the past, H5N1, have been confirmed in Scotland and England in recent weeks. The widespread effect of the outbreak has prompted the Department for Environment, Food and Rural Affairs to extend protection, surveillance and mandatory housing orders across the two countries.
