ODFW reports increase in bird flu cases among ducks and geese in Willamette Valley
SALEM, Ore. (KTVZ) — Reports of highly pathogenic avian influenza (HPAI) are increasing among ducks and geese migrating through Oregon, with the majority of sick and dead birds being reported in the Willamette Valley.
The Oregon Department of Fish and Wildlife (ODFW) says the Cackling goose, a smaller subspecies of the Canada goose, appears to be the most heavily affected.
ODFW is urging the public to avoid contact with sick birds and keep pets away from them. People are also advised not to capture or transport sick birds to wildlife rehabilitation centers, as there is no effective treatment for infected wild or domestic birds.
The virus can spread rapidly among bird populations and potentially to other wildlife.
Signs of avian influenza in birds
Symptoms in wild waterfowl can include:
Lethargy or inability to fly Erratic behavior or loss of coordination Cloudy eyes Swimming in circles Head shakingSome ducks may carry and spread the virus without showing symptoms. Birds that develop clinical signs typically die within 72 hours.
Infected wild mammals may also appear sick, show neurological abnormalities or be found dead after consuming infected birds.
How to report sick or dead birds
ODFW says its Wildlife Health staff have been collecting and testing birds to monitor the outbreak. The agency does not need additional bird collections for testing at this time.
However, the public is encouraged to report groups of dead birds that show no obvious signs of illness before death.
Reports can be made by calling 866-968-2600 or emailing wildlife.health@odfw.oregon.gov. Due to the high volume of reports, staff may not be able to return calls.
If disposing of a dead bird, ODFW recommends wearing disposable gloves and a mask and double-bagging the carcass before placing it in the trash.
The public should also report sick or dead domestic birds, including chickens, turkeys and guinea fowl, to the Oregon Department of Agriculture at 503-986-4711 or 800-347-7028.
Risk to people remains low
According to the U.S. Centers for Disease Control and Prevention (CDC), the risk of avian influenza to people remains low.
Since 2024, there have been 74 confirmed human cases of avian influenza in the United States, including three deaths.
