I have heard of ducks getting upwards of 15 yrs old. My buddy shot a banded duck one day and the band was so old it was worn smooth and almost worn off...we took it to F&G office and they told us he could still send it in and they use some sort of acid wash to bring out the #s but it pretty much will destroy the band so my buddy just opted to keep it and not send it in. The biologist figured to be up in that range of 12+ just judging on the condition of the band.
Canada geese (canadian geese can't cross into the US
)can live past twenty, but on average it is much lower. Hell, probably 1/3 don't make it through the first year. I would think 8 - 12 years is probably a pretty good range for those making it the first year.
As for the worn bands, the USFWS can use a wash to distinguish the numbers and it will not destroy the band. I don't have a personal experience with it, but spoke to one of the technicians at the lab.

I am surprised the biologist guessed the band to be that old. In my opinion, more of an impact on the band is a correlation of what type of habitat the goose used. In other words, if this was a bird that spent most of the year in sandy or gravel bottom shallows then the band would wear much quicker than one that inhabited a soft mudded marsh.
Hell, I am no waterfowl biologist, so take it for its worth.
Anyway, cool band stories. How far away were these guys banded?
I shot 2 geese that were neck/leg banded. The cool thing is the numbers were in sequence following each other, but to top that I shot both geese almost a yr apart from each other. I shot one in december of one yr and the other in an early goose hunt in september of the following yr. I sent off the first band #s and it came from Ladd Marsh in La Grande OR and I killed both geese off same reservoir in Juntura OR about 100 miles away as the crow flys. One neck band got a few pellets to it but the other is mint, I planed on having them mounted someday but never have.
This is the site to go to if you have any waterfowl questions. If you do any dog training like I do then check out the gundog forum on this site as well. To find out all you want to know about the ages of waterfowl go on the Duck hunters forum on this site and ask all questions. Good luck.
The oldest duck I have ever killed is a Black Duck that I killed in 2000. When I called the band in the lady told me the bird was banded in 1986.Then she sent the certificate that said it. The band was paper thin almost to the point of breaking when I took it off.
A friend of mine killed a goose in SW MT that was twelve. It was banded about 6 miles from where it was shot. I couldn't belive it made through all those seasons. They get hunted pretty hard around there.
