Data from: Ecology of tern flight in relation to wind, topography and aerodynamic theory ...

Flight is an economic mode of locomotion, because it is both fast and relatively cheap per unit of distance, enabling birds to migrate long distances and obtain food over large areas. The power required to fly follows a U-shaped function in relation to airspeed, from which context dependent ‘optimal...
