Minnesota Trumpeter Swan Population Keeps Growing
A statewide aerial survey finds Minnesota's trumpeter swan population more than doubled in the last five years. The survey was conducted Jan. 5-8. It found more than 5,300 trumpeter swans in 14 Minnesota counties. But the actual number of trumpeter swans in Minnesota last September is estimated at 5,500.
