A beautifully executed project here, I bought Neal a coffee.

What evolutionary advantage, I wonder, is there to Ruppell's griffon vulture flying at 11400 meters?

Not every behavior has an evolutionary advantage.

If anything, "evolution" filters out disadvantages (eg: can't survive because your neck's too short and that pesky giraffe is eating all the leaves you could reach).

Evolution kills what doesn't work.

but every behaviour has a cost. In cast of flight altitude its energy and distance to food, water, mating zones.

Having a cost and being too costly aren't the same thing though.
