Albatrosses are monogamous, so a particular bird can be recognized both by its band and its mate. Apparently Wisdoms mate only recently stopped appearing with her, so any shenanigans like are alleged to have happened with Jeanne Calment would be complicated. You'd have to fake the survival of two beings, not one, by, for example, capturing both members of the pair and swapping their bands onto the legs of another, similar bonded pair.
