The word for "altitude-meter" is altimeter....
Vultures have an extremely acute sense of sight..far better that ours..
they can figure distance with their relation to the ground...
Also: I don't think a vulture cares how high it is per se but whether or
not it has a good vantage point...if he gets caught in a down-draft..he'll
just land or flap...if a glider gets in a down draft...it'll crash and the
pilot dies. So you can see that the answer to your question depends on
