As spring approaches, many bird lovers begin to replenish their feeders, hoping to attract various species to their backyards. For both dedicated birdwatchers and casual observers, witnessing the beauty of birds visiting is truly delightful. However, following the emergence of a potent strain of avian influenza in 2022, some specialists have recommended that bird feeders be put away. This raises the question: should you really consider stowing your bird feeder for the time being?
What is avian influenza?
Avian influenza, commonly known as bird flu, is a severe illness that primarily affects birds. Its outbreaks can impact commercial poultry farms, smaller flocks, as well as wild and pet birds. There are numerous strains of avian influenza, each differing in severity. The H5N1 strain circulating in North America is particularly concerning, with a mortality rate for infected birds ranging from 90 to 100 percent.
How does avian influenza spread?
The virus can easily be transmitted by an infected bird through its droppings and respiratory secretions. Remarkably resilient, the virus can survive on various surfaces for extended periods, making it possible to infect other birds. Waterfowl like geese and ducks, along with raptors such as hawks and eagles, are especially vulnerable, although virtually any bird species can contract the virus.
Is avian influenza dangerous to humans?
While avian influenza can potentially be harmful to humans, it is notoriously challenging to contract and even trickier to transmit. Symptoms in humans can vary significantly, ranging from none to mild flu-like signs, including fever, cough, sore throat, nasal congestion, body aches, and fatigue. There have been instances of more serious conditions like pneumonia, but severe outcomes are rare, making avian influenza mostly non-threatening to people.
What’s the deal with bird feeders?
Interestingly, certain wildlife experts, including those from the BC Society for the Prevention of Cruelty to Animals (SPCA), advise that bird feeders should be offered primarily during the colder winter months. With ample natural food available in the spring and summer, feeders are often unnecessary. Instead, to attract birds, consider cultivating a variety of native plants and flowers in your garden.
What can I do to help?
The current advice to take down bird feeders and empty birdbaths mainly pertains to properties with poultry and other domesticated animals. While songbirds are less likely to contract or spread avian influenza, the BC SPCA cautions that feeders and baths can lead to crowded gatherings of birds, thereby increasing the risk of transmission. Additionally, seeds that fall to the ground may attract birds to droppings that accumulate below feeders.
Is there anything else I should do?
In addition to removing bird feeders and baths, ensure that any outdoor surfaces with droppings are cleaned thoroughly. Avoid handling or feeding wild birds directly. Stay vigilant for any signs of sick birds in your vicinity; if you encounter ill or deceased birds, it’s important to report them to your local wildlife agency. For instance, in Canada, you can utilize the Canadian Wildlife Health Cooperative’s online tool or call 1-800-567-2033.
By taking these precautions, we can contribute to the safety and well-being of our beloved avian companions while enjoying their charming melodies.
