Good question; do you mean maximum observed altitude or maximum 
expected based on planform and mass?

The maximum observed altitude would, I think, be that recorded for 
molossid bats during long distance foraging.  I don't know what the 
figure is off the top of my head, but I can find it easily enough 
(perhaps someone onlist has it handy).  Maximum altitude expected from 
morphology and flight dynamic is going to be trickier... I'm not sure 
what that would be for bats without doing some calculations.

I'll look up that molossid tracking work and get the altitude report as 
soon as I have a chance.
