ST. LOUIS Trumpeter swans are back at the Audubon Center Riverlands Migratory Bird Sanctuary near the Alton Bridge.
According to Patricia Lueders, volunteer coordinator of the Great Rivers Trumpeter Swan Watch, more than 400 of the waterfowl were seen there this week.
They are called trumpeters because of their vocalization, which sounds like a trumpet. It s estimated that they live for 20 years.
Lueders said the oldest swans at Riverlands are more than 15 years old. Volunteers have been counting and monitoring the birds winter behavior for the Trumpeter Swan Society since 2012.
