Flying, Vigilance
"The surely exist. Indeed, what else can account for
the complete and absence of half a herd of elephants?
Yet many sightings are probably just tricks of the eye.
Birds closer than they seem. The most likely sightings
are impassibly high mountains or far out at sea.
Barring one falling out of the sky somewhere civilized
they are an impossible study."
