Bird shows are banned from Monday, following the spread of bird flu across the UK.
Defra has released new guidelines today that no gatherings involving poultry, ducks, geese, pheasants, turkeys, guinea fowl, partridge and quail are allowed.
Gatherings involving other birds are allowed, but organisers must apply for a licence at least seven days before the event.
Gatherings include bird fairs, markets, shows, sales, exhibitions and some premises used for dealing or internet sales.
Vehicles used to transport live birds where the birds are brought together from multiple premises (so called many-to-one or many-to-many activities) are also considered gatherings.
On Wednesday, new measures were rolled out to help stop the spread of avian influenza.
It is now a legal requirement for all bird keepers in Great Britain to follow strict biosecurity measures to help protect their flocks.
The Avian Influenza Prevention Zone means that keepers with more than 500 birds will need to restrict access for non-essential people on their sites, workers will need to change clothing and footwear before entering bird enclosures and site vehicles will need to be cleaned and disinfected regularly to limit the risk of the disease spreading.
Avian influenza circulates naturally in wild birds and when they migrate to the UK from mainland Europe over the winter they can spread the disease to poultry and other captive birds.
Backyard owners with smaller numbers of poultry including chickens, ducks and geese must also take steps to limit the risk of the disease spreading to their animals.
UK health agencies advise that the risk to public health from the virus is very low and the UK food standards agencies advise that avian influenzas pose a very low food safety risk for UK consumers.
Properly cooked poultry and poultry products, including eggs, are safe to eat.
The introduction of the AIPZ comes after the disease was detected in captive birds at premises in England, Wales and Scotland.
The disease has also been detected in wild birds at multiple sites across Great Britain.
