A pair of nervous trumpeter swans give a head-bopping warning display with a cygnet (juvenile swan). Cygnets have a gray or brownish wash on their head and neck. This species almost went extinct due over hunting and habitat loss. Reintroduction programs in the Upper Midwest have had great success in bringing this species back from the brink.
