They're back.


Large numbers of Tundra swans have arrived at Rondeau Provincial Park, Ontario, Canada, March 12, 2019.
This is a small portion of the swans roosting on the ice. They were about a mile out.


Cygnus columbianus
Based on banding records, the oldest known Tundra Swan was a female and at least 23 years, 7 months old when she was identified by her band in the wild, in Ohio. She had been banded in the same state.
