Trumpeter Swan Restoration

Prior to the settlement of Iowa, trumpeter swans (Cygnus buccinator) nested throughout the state. However, wetland drainage and unregulated hunting of trumpeters soon brought their demise. Until 1998, the last wild nesting trumpeter swan in Iowa occurred in 1883 on the Twin Lakes Wildlife Area southwest of Belmond, Iowa in Hancock County. In 1998, three cygnets hatched from a wild nesting trumpeter pair in Dubuque County. This pair hatched 5 in 1999 and 5 again in 2000.
