Really? Not 7 months in at least one of these cases? :)
OK, I'm kidding, because longetivity records are just that, RECORDS.
For all we know they can live to 128 years and 129 months...
A question, though, has anyone (not here, I mean academically which
could also mean here, of course) worked out the longetivity records
vs. banded birds/recovered at other ages to determine a statistically
acceptable higher limit on age for such species? I'd think that given
enough banding data one would end up with a standard distribution that
could at least assign probabilities of older birds than those known to
have been recovered being banded yet not recovered.
(that's convoluted, but hopefully some will understand).
