OMAHA, Neb (AP) — The Nebraska Game and Parks Commission is investigating after about 300 snow geese were killed and left piled on a road in Richardson County.

According to a release from the agency, the dead birds were discovered west of Falls City.

Thousands of snow geese are migrating through Nebraska and there is no hunting limit on the birds. But Nebraska game and parks officials say it is illegal not to clean and properly dispose of the birds.

Those who were involved could face misdemeanor charges if they didn't have proper hunting permits or stamps. They also could face misdemeanor charges for littering a waterway and wanton waste.
