The Treadmill of Survival

Writes Louis-Pierre Vieillot,

The passenger pigeons have their own unique way of plucking acorns: they climb continuously up and down the oak trees; they ascend one after another, and each beats its wings two or three times to knock off then descends to eat its own or those that the others have knocked down. The activity of ascent and descent creates a perpetual motion.

And one we’ll never see again.
