MADISON, WI (WTAQ) - Wildlife experts in Madison have determined that a tundra swan found dead in Alaska had become extremely thin.
The swan was one of two found dead on New Year’s Eve at the Mendenhall Wetlands State Game Refuge in Juneau Alaska.
One of the swans was sent to the National Wildlife Health Center in Madison to be checked.
The center said the bird was emaciated, but it could not be determined why. Poisoning was ruled out.
Alaskan officials say about 100 swans visit Juneau each year on a migratory path.
State biologist Ryan Scott says they often head to the tidal salt marshes, where they feed on aquatic vegetation.
