Argentavis

Argentavis did not flap. It did not need to. Its wings — wider than a small

dwelling, membranes of feather and bone stretched to impossible proportions

— caught the thermal currents that rose from the ancient Andes and carried

it upward without a single beat. From that height, the world was a map. The

herds below were specks. The rivers were silver threads. The predators and

prey that defined life on the ground were a pattern viewed from so far above

that the violence became almost beautiful. Argentavis was a soarer, not a

hunter — though it could hunt, and did, when the wind brought it close to

something slow enough to catch. But its true dominion was altitude. The sky

of the Resurgence was wider and emptier than it had been since Pteranodon

vanished, and Argentavis claimed it with the quiet authority of something

that had found the one place in the world where nothing could touch it. To

be the largest thing in the sky is to be, in a sense, the freest thing alive.
