A pair of wintering Trumpeter Swans taken a couple of weeks ago. There are several sightings of wintering Trumpeters in OK this year. Significant to their long-term survival because the birds in the Central Flyway have all been transplanted with birds from the Rocky Mtns. and eggs from Alaska. Migration is a learned behavior passed from generation to generation. Looks like they are learning to migrate south.
