Abstract

6 barnacle and 6 bar-headed geese will be trained to fly in a large wind tunnel and the relationship between heart rate (fH), heart mass, cardiac output, arterial oxygen uptake, oxygen consumption (VO2), carbon dioxide production and flight speed will be investigated. Wing morphology and wing beat frequency will be measured and comparisons made between steady-state VO2 and aerodynamic power output models. As VO2 has not been measured directly from birds with a mass greater than 0.5 kg while flying at a range of speeds in an aerodynamic wind tunnel, this study will increase this body mass range by up to 7-fold. The derived relationship between fH and VO2 (walking/running and flying) will subsequently be used to estimate the energy expenditure of free-living wild geese based on their recorded fH.
