(Salem, OR) -- Oregon Department of Fish and Wildlife says many rehabilitation centers for birds aren't accepting waterfowl, because of bird flu risks. They can carry the virus without showing symptoms and potentially infect other birds in the facilities. If you find ducklings or goslings without a parent nearby, leave them alone because the parents will usually return. Injured ducks or geese should be brought to an ODF&W office for euthanasia. If you see sick or dead wild birds, leave them where they are and call ODF&W.
