Energetics and migration performance. The prerequisites for migration differ a lot between animals that swim, fly or run. To illustrate this, compare the performance of animals of e.g. one kilogram body mass: for a sea mammal or fish of this size, the typical swimming speed would be around 0.5 meters per second (m/s), while a would fly at 16 m/s and a mammal …
