I guess the question then becomes: which final air forms will really want to avoid high-altitude fights against which other air forms.

This is complicated by the fact that some air forms are *neither* predator *nor* prey. Unless the info on the wiki is just outdated.

Predators: Golden Eagle, Falcon, Vulture
Neither: Great Horned Owl, Vampire Bat
Prey: Tiny Hummingbird, Giant Wasp

So in theory a hummingbird should find it "very" difficult to flee from a Vulture and an Owl/Bat should find it "somewhat more" difficult to flee from a Vulture, by virtue of the vulture being a predator?

Bleh. So confusing.
