Utah is just one of nine states that allow swan hunting, and until this year, that included trumpeter swans, considered North America’s largest bird. The trumpeter swans are still struggling to reestablish migratory populations nearly a century after hunters blasted them to near extinction.But now Utah wildlife officials have proposed banning the taking of trumpeter swans. Tundra swans would remain legal to shoot during Utah’s 73-day fall swan-hunting season.
