Tracking The Lost; No transmitters?

Peter: Once the eagles lose their transmitters and eventually wingtags, do you know them well enough to be able to identify them or do they mostly look so much alike that you cannot tell at that point?

It is nearly impossible to tell the bald eagles apart without the wing tags, so we generally don't know who is who when that happens.

Further to this train of thought, if a nesting pair returns year after year to the same nest while still wearing identifiable wing-blings and then their IDs disintegrate, can it be assumed that they are still the original pair when observed in subsequent years at the same nest? Are there behaviours that would be specific enough that under the camera's 'eye' would be identifiable or would it be impossible to know if, 11 years from now, K-26 returned to the nest with a young stud in tow? I'm sure with the proliferation of 'cams' and more knowledgeable field observers, that we will all know a lot more in the coming years but what is known/assumed now?
