Swan Collaring Protocol

There are extensive collaring efforts for both Trumpeter and Tundra Swans, while the introduced Mute Swan is rarely marked. The recent (1993) protocol for swans calls for different colors for each species as well as differences in the codes. Like Canada Goose collars, swan collars are unique and each collar combination of codes and color is used for only one band number.

Mute Swan

Because of the recent change in collar protocol for swans, there are Trumpeters with 4-digit collars from the previous protocol. These collars have an LLNN pattern and are often yellow and black. The Mute Swan protocol remains unchanged.
