Beauty and miraculous evolution of avian flight

A photo of a frigatebird in flight, sent from Ecuador by my daughter-in-law, set me to thinking about the beauty and miraculous evolution of avian flight.

How extraordinary it is that a creature only minutes hatched from an egg can take to the air, while we humans, however long we’ve been out of the womb, can fly no higher than two feet above the earth, and even Olympiad high jumpers and long jumpers can stay airborne for no more than a few seconds.
