Its a type of band, called an auxiliary marker.

"Nasal saddles and discs are auxiliary markers frequently used on ducks. Nasal saddles fit over the bill and are attached with a metal rod through the nares (nostrils). These markers are often inscribed with unique codes and come in various color combinations. Nasal discs, small plastic markers of various colors and shapes, are similarly attached on either side of the bill. These markers have been extremely useful in studying local movements, fidelity to nesting and wintering areas, survival, and behavior. Despite their somewhat cumbersome appearance, nasal saddles and discs do not seem to adversely affect the survival of birds wearing them."

I assumed it was installed.  I doubted anything random would have been balanced equally on each side.
