Hi Jim,

The longevity record from banding data (bird in the wild) is now 30
years 9 months. The reference for the 48 years for a captive bird
appears to come from the Handbook of Birds of the World, Vol. 1. 1992.

All the best,

Lance

	JUNE 24, 2008 - Today on "As It Happens" on CBC Radio, there was
an interesting report on BALD EAGLES IN THE ASSINIBOINE ZOO IN WINNIPEG:
Bob Wrigley reported that they have a reproducing pair of  ELDERLY
eagles there that go all the way back to 1973, when both of them got to
the zoo as already in adult plumage (thus at least 5 years old, born in
1968 or earlier, thus at least 40 years old this year); in 1973 they
were from two different provinces (Manitoba and ??) and needed
rehabilitation (both were injured and unreleasable); a NINE-YEAR
COURTSHIP ensued, after which they produced their first eaglets in
1983?; this year, 2008, they have remarkably produced their 22nd and
23rd youngsters, after a couple of years of no successful reproduction
(3 or 4 years ago they had one youngster); both adults still look to be
healthy and vital; their current ages of 40+ years can be compared with
the maximum known longevity in captivity of 48 years, I believe, and up
to 27 years for wild bald eagles; thus these two are pretty remarkable,
it seems.  I haven't yet tried to check on this via Googling or other
Internet sources nor my books and articles.

	I'm wondering if anyone else also heard this radio report and
can comment further on my notes or other relevant information??

	Cheers from Jim in Wolfville.
