MUD LAKE, Idaho (KTVB) -- Wildlife officials say 2,000 migrating snow geese have died in eastern Idaho likely because of avian cholera.

The Idaho Department of Fish and Game says staff and volunteers collected the dead birds over the last several days at the Mud Lake Wildlife Management Area near Terreton and the Market Lake Wildlife Management Area near Roberts.

A smaller number of dead snow geese were reported Friday at the Camas National Wildlife Refuge near Dubois.

Authorities say the geese were migrating from the southwest United States and Mexico to breeding grounds on the north coast of Alaska.

Fish and Game spokesman Steve Schmidt says it's not clear where the geese picked up the avian cholera.

Health officials say humans aren't at a high risk of infection from the bacteria.
