Show Notes
This story begins thousands of feet up in the air with migratory birds, and ends with a robotic fish swimming through the water below. To prepare for their journeys, birds fatten up big time, perhaps doubling their weight, essentially turning themselves into feathered batteries. Over many days and many miles, they burn that energy reserve to power their wings and keep themselves from starving and freezing. Eventually they reach their destinations emaciated.
