We know that avian bird flu is affecting poultry and egg production in Australia, but what are the risks to native birds, and what can be done to stop the spread? 

The information below has been shared by Ingrid Marker from Cassowary Keystone Conservation. 

What we know so far:

• Avian flu is having a disastrous impact on migratory sea and shore birds, and penguins in Antarctica, global freshwater aquatic bird species, marsh and wetland species, waders etc.
• Many migratory species are migrating now from hot spots of the disease transmission to Australian shores and our wetlands, particularly in the north
• Currently we do not have any recorded cases in Australia in native bird species, only a few poultry producers
• The virus is most rapidly spread through gregarious species or large flocking species
• The virus is lethal and can wipe out an entire flock within 2-10 days
• The virus can survive in the environment if moisture or fresh or salt water is present for up to 100 days on many surfaces
• It can withstand freezing temperatures
• It is spread by aerosol
• It has crossed into mammals that eat carrion or prey on birds, such as seals, killer whales, dolphins, bears and wolves
• A few humans have contracted it (cause unknown) and have become very ill. 

Prevention

Good hygiene is important for prevention, with particular attention to washing all feeders and water containers with chlorine to disinfect.

Potential spreaders include:

• Backyard bird feeders, bird baths and ponds
• Backyard poultry hobby farmers
• Backyard breeders of pigeons/doves
• Fish/prawns farms
