The takeaway: Could avian flu be present at your smart bird feeder? Songbirds do get avian flu. Here’s what you should know and how you can help stop its spread.

Large birds like raptors, shorebirds, and waterfowl–as well as domestic poultry–tend to grab headlines when it comes to avian flu. But other birds can be impacted, and that can even include the birds that visit your smart bird feeder.

What Is Avian Flu?

Avian flu is a contagious viral disease that mainly affects poultry and wild waterfowl. It is caused by the influenza type A virus, most notably H5N1 although there are others. Some strains cause just a mild illness, while more severe or pathogenic strains can cause severe outbreaks and high rates of bird death. Although rare, avian flu can infect humans and other animals through direct contact with infected birds.

Where Is Avian Flu Most Common?

Avian flu is most common in situations where wild waterfowl mix with domestic poultry, particularly in Asia, Africa, and Europe. China, Vietnam, Indonesia, and Egypt have frequent outbreaks due to dense poultry farming methods and the presence of live bird markets. In recent years, North America and Europe have also seen major outbreaks among wild birds and poultry farms, with these outbreaks commonly being blamed on migrating waterfowl that carry the disease over long distances.

Can Songbirds Get Avian Flu?

Yes, songbirds like those who visit your FeatherSnap smart bird feeder can get avian flu, although it is not common. Songbirds like sparrows, finches, robins, and cardinals are less susceptible to avian flu than waterfowl or poultry. They can become infected, especially with highly pathogenic strains like H5N1, but they rarely spread the virus. 

What Happens to Songbirds When They Get Avian Flu?

What happens to songbirds if they happen to get avian flu depends on which strain it is and which bird species it is.

  • Mild strains: Songbirds may have no symptoms at all, or just mild symptoms like ruffled feathers.

  • Severe strains: Songbirds may experience serious illness or death, although this is rare. Symptoms can include lethargy, weakness, trouble flying or balancing, swollen eyes or head, tremors, or twisting of the neck.

Because songbirds are generally less susceptible to avian flu they are not considered major carriers or spreaders. But, if one does get sick, it can die quickly. This is because their bodies are not well adapted to handle the virus. Highly pathogenic flu strains can multiply quickly in a bird’s organs and tissues and overload their immune system before any defense can be summoned.

Once established, the virus can quickly spread from the respiratory or digestive tract to the brain, heart, and other vital organs, causing them to fail. Further, songbirds are tiny and have limited energy reserves, meaning that once sickness sets in, their energy is quickly depleted and recovery becomes unlikely.

Do Hummingbirds Get Avian Flu?

Yes, hummingbirds can and do get avian flu. As with songbirds, the infection rate is generally low, but once infected, disease rates tend to be high. Transmission typically occurs at feeders through saliva, mucus, and droppings. Symptoms that you might observe at your smart hummingbird feeder include lethargy, inability to hover, and loss of coordination.

How Does Avian Flu Affect Birds at the Cellular Level?

So here’s what really happens when a songbird catches avian flu. Avian flu virus attacks a bird's respiratory and digestive cells: the virus is composed of RNA and a cluster of proteins that stick to receptors in the bird’s body, enter the cells, and replicate rapidly. This causes cell death, inflammation, and tissue damage. In advanced cases, the virus then travels through the bloodstream to vital organs like the brain, heart, and liver, leading to organ failure. The process that the bird’s immune system uses to fight the infection can lead to additional inflammation, causing shock and quick death.

How to Prevent Avian Flu From Spreading at Your Feeder

Follow these steps to help prevent the spread of avian flu at your smart bird feeder:

  • Clean your feeder regularly. Wash every week or two with a mild dish soap and water, then rinse thoroughly. Sanitize the feeder using a 10% bleach solution, then rinse and dry everything thoroughly. Use a dedicated brush and bucket for cleaning your feeders, not the kitchen sink or brushes that you use for dishes.

  • Remove waste. Keep the area under the feeder free of droppings, shells, and moldy seed.

  • Avoid crowding. Is your feeder super busy? Get a second one and space it a few feet away.

  • Pause feeding if you notice sick or dead birds. Look for signs of avian flu by monitoring the health of your birds through the feeder app. See something? Take the feeder down for a week or so.

  • Provide fresh seed or nectar. Replace old or damp seed to discourage bacteria and fungus buildup.
