SpletFlight is the characteristic adaptation of birds. The energetic cost of moving a unit of weight a unit distance in air (the dimensionless cost of transport) is rather low. For a given body mass, flying is a far more inexpensive way to move than is running, although it is more expensive than swimming (Schmidt-Nielsen 1984).
