Identifying Illness in UK Garden Birds: Key Symptoms and Essential Action Steps

As we enjoy the vibrant presence of birds in our gardens, it's crucial to be aware of the health of these feathered friends. With the increasing global concern about avian influenza, particularly the highly pathogenic avian influenza (HPAI) H5N1, it's more important than ever to know how to identify illness in garden birds and what actions to take.

Understanding Avian Influenza

Avian influenza, or bird flu, is a highly contagious viral infection that affects birds. The HPAI H5N1 subtype is particularly alarming due to its high mortality rate among birds and potential transmission to other species, including humans.

What is Avian Influenza?

Avian influenza is caused by viruses that are grouped by two surface proteins, haemagglutinin (HA) and neuraminidase (NA). The H5N1 subtype is one of the most concerning due to its high pathogenicity and global spread. Wild birds are considered the natural hosts for these viruses, but they can also infect domestic poultry and other bird species.

Key Symptoms of Avian Influenza in Garden Birds

Identifying the symptoms of avian influenza in garden birds is the first step in taking action to protect both the birds and human health.

Visible Symptoms

Here are some key symptoms to look out for:

Lack of Coordination and Neurological Signs: Birds may exhibit tremors, swim in circles, or show twisted necks or other unusual postures.
Respiratory Issues: Noisy or rapid breathing, coughing, sneezing, and increased nasal secretions.
General Health Decline: Diarrhoea, difficulty breathing, swelling around the head, neck, and eyes, and a rapid decrease in feed and water intake.
Behavioral Changes: Lethargy, depression, unresponsiveness, lying down, and dragging legs.
Physical Changes: Ruffled feathers, closed and excessively watery eyes, and purple discolouration of the comb and wattles in domestic birds.

Reporting Sick or Dead Birds

If you notice any of these symptoms or find dead birds in your garden, it is essential to report them immediately.

How to Report

In the UK, you should contact the Animal and Plant Health Agency (APHA) or the local animal health office. Here are the steps to follow:

Contact Details: Call the Defra helpline on 03459 33 55 77 or report online through the GOV.UK website.
Provide Detailed Information: Include the location, number of birds affected, and any photos or videos that can help in the identification.
Do Not Handle the Birds: It is crucial to avoid handling sick or dead birds to prevent the risk of transmission.

Surveillance and Control Measures

Surveillance and control measures are critical in managing avian influenza outbreaks.

Surveillance Activities

Surveillance involves monitoring bird populations for signs of illness. Here are some key activities:

Bird Monitoring: Regularly check for sick or dead birds in your garden and nearby areas.
Wild Bird Surveillance: Collaboration with birdwatchers, land managers, and researchers is essential for early detection of outbreaks.
Commercial Poultry Surveillance: Farms and commercial poultry premises must conduct regular health checks and report any suspicious signs immediately.

Control Zones

In the event of a confirmed outbreak, control zones may be established to contain the spread of the disease.

Surveillance Zone: An area around the outbreak where enhanced surveillance and biosecurity measures are implemented.
Control Zone: A restricted area where movement of birds and bird products is controlled to prevent the spread of the disease.
Example from Breckland, Norfolk: In cases where an outbreak is confirmed in a specific area, such as Breckland in Norfolk, a surveillance zone and control zone may be established to ensure the disease does not spread to other areas.

Biosecurity Measures for Garden Bird Enthusiasts

Maintaining good biosecurity practices can help prevent the spread of avian influenza to your garden birds.

Cleaning and Disinfection

Regular cleaning and disinfection of bird feeders, baths, and other equipment can reduce the risk of virus transmission.

Use Disinfectants: Use approved disinfectants to clean all bird-related equipment.
Change Water Frequently: Ensure that water in bird baths is changed regularly to prevent contamination.

Avoiding Contact with Wild Birds

Minimize contact between your garden birds and wild birds to reduce the risk of disease transmission.

Use Netting or Covers: Cover bird feeders and baths with netting to prevent wild birds from accessing them.
Keep Domestic Birds Indoors: During high-risk periods, consider keeping your domestic birds indoors to prevent exposure to wild birds.

Practical Insights and Actionable Advice

Here are some practical tips and advice to help you manage the risk of avian influenza in your garden birds:

Measure	Description
Clean and Disinfect	Regularly clean and disinfect bird feeders, baths, and other equipment using approved disinfectants.
Change Water Frequently	Change water in bird baths daily to prevent contamination.
Use Netting or Covers	Cover bird feeders and baths with netting to prevent wild birds from accessing them.
Keep Domestic Birds Indoors	During high-risk periods, keep domestic birds indoors to prevent exposure to wild birds.

Quotes from Experts

Dr. Carol Booth, Invasive Species Council Principal Policy Analyst: "We’ve been campaigning for over a year to get the government to prepare for the looming H5N1 catastrophe. This $100 million of federal funding is a significant step, but more will be required if this disease hits our shores."
Agriculture Victoria: "All bird owners need to be vigilant for any signs of avian influenza in their flocks. Early detection and reporting are crucial in managing outbreaks."

Identifying illness in garden birds and taking prompt action is vital in the fight against avian influenza. By understanding the symptoms, reporting sick or dead birds, and implementing robust biosecurity measures, we can protect both our garden birds and the broader bird population.

Completion of Disease Control Measures

Following the successful completion of disease control measures, such as the establishment of surveillance and control zones, the risk of avian influenza can be significantly reduced.

Zone Revoked: Once the outbreak is under control, the surveillance and control zones can be revoked, and normal activities can resume.
Activities Surveillance: Continuous surveillance activities ensure that any future outbreaks are detected early, allowing for swift action to be taken.

By staying informed, taking proactive steps, and collaborating with local authorities, we can ensure the health and well-being of our garden birds and contribute to the broader effort to control avian influenza.
