Trumpeter swans released in Teton Valley (Driggs Area) as part of a reintroduction program over the past 4 or 5 years also (unfortunately) have green collars w white lettering, and, too, the alphanumeric code starts with R.

> Very cool, Chuck! If the green collar had white letters/numbers, the bird was collared by our staff on Two-way Pond at Camas National Wildlife Refuge on July 25, 2018. The collaring is being done as part of a study we are engaged in to determine the cause of low reproductive success of Trumpeter Swans at refuges in the Complex.
