Avian influenza spreads

On Jan. 12, 2026, the New York State Department of Environmental Conservation released an advisory for New Yorkers about rising cases of avian influenza (HPAI) as bird migrations continue through winter and spring. According to their press release, “HPAI has been confirmed in red fox, striped skunk, Virginia opossum, raccoon, fisher, gray squirrel, muskrat and bobcat, as well as a wide range of other mammals in New York State.”

“In November and December 2025, DEC received 69 reports of suspect mortalities through its online reporting platform, and presumptive positive cases were detected in wild birds in 10 counties.  With migration beginning, HPAI incidence may remain high through spring, particularly associated with the migration of large numbers of ducks and geese through the state.”

“We are definitely seeing a huge uptick in what we would characterize as avian flu amongst mostly waterfowl,” said Janine Bendicksen, director of Wildlife Rehabilitation, Sweetbriar Nature Center. “We received over 19 Canada geese last week alone, all presenting with avian flu. All were euthanized or died overnight in the Stony Brook area. These numbers are followed by swans, ducks, and gulls. It is very difficult to know if any mammals have been affected. We have no way of easily testing for the virus.”

Evelyn Alexander Wildlife Rescue Center has reported seven suspected cases to the DEC for testing as well, said Grace DeNatale. “I would say it’s a good idea to know what symptoms most often appear, but more important still is that the range of infection is wide. An infected animal could be anywhere from unresponsive, to seizing, to just a bit off, dull and sluggish. For the public, it is important to act with caution around wildlife, no matter the presentation.”

To help protect yourself and your pets, do not allow dogs to run off leash, especially in areas frequented by waterfowl like ducks, geese and swans.  Avoid stepping in feces since it can also be a source of transmission. Do not throw dead animals into waterways, since the virus can spread to other animals that way. And remember that cats are especially susceptible to this virus. Consult your veterinarian immediately if you suspect your pet has become sick or has had contact with a dead or sick animal.

If you come upon a sick or dead animal, contact a local wildlife rescue organization like EAWRC (631 728-WILD), STAR (631) 736-8207, or Sweetbriar (631) 979-6344. You may also contact a local DEC office to request removal of dead birds and help prevent further spread of the virus.

Birds of prey, like bald eagles, hawks, osprey and owls, and scavengers like crows and gulls are susceptible because they often consume the remains of infected animals. 

Farmers who keep chickens, have barn cats, or raise cows or ducks, are advised to monitor their animals for signs of illness as domestic poultry and dairy cows have been infected, as have barn cats.

According to the United States Centers for Disease Control and Prevention, “HPAI and H5N1 have been detected in more than 70 humans in the United States, including two mortalities; most of these cases involved close contact with infected domestic birds or cows.”

At present, it is not considered a serious risk to humans, although those who are immunocompromised would be at greater risk of infection.
