The Combined Effects Of Air Temperature, Wind, And Radiation On The Resting Metabolism Of Avian Raptors, Steven R. Hayes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
American kestrels, Falco sparverius; red-tailed hawks, Buteo jamaicensis; and golden eagles, Aguila chrysaetos, were perched in a wind tunnel and subjected to various combinations of air temperature, wind, and radiation. Oxygen consumption was measured under the various combinations of environmental variables, and multiple regression equations were developed to predict resting metabolism as a function of body mass, air temperature, wind speed, and radiation load. Heat transfer analysis of the bird-thermal environment relationship was conducted to produce a biophysical model describing resting metabolism as a function of feather thermal conductance.
Because of differences in surface area to mass …
