The power that the birds can use for flight (available power) and the power required for flight according to physical laws (requisite power) grow with an increase in body mass, the exponents of the corresponding functions being different. Small birds can follow different strategies, either improving the aerodynamic quality of the body (thereby saving the excess available power) or sacrifice aerodynamic quality in favor of morphological adaptation to factors other than the demands of flight… Expand
