The bat in question was (I beleive) a Mexican Freetail, which tend to be
in torpor from December through March in our warmer California
temperatures.   Pretty incredible little bat- "Mexican free-tailed bats
sometimes fly up to two miles high to feed or to catch tail-winds that
carry them over long distances at speeds of more than 60 miles per

The Bat Conservation International bat trivia page
(http://www.batcon.org/trivia.html ) refers to a Little Brown bat living
32 years.  "The common little brown bat of North America is the world's
longest lived mammal for its size, with life-spans sometimes exceeding
32 years"

There are nearly 1,000 species of bats, and lifespans are not known for
most of them.
