Metabolic power, mechanical power and efficiency during wind tunnel flight by the European starling Sturnus vulgaris.
We trained two starlings (Sturnus vulgaris) to fly in a wind tunnel whilst wearing respirometry masks. We measured the metabolic power (P(met)) from the rates of oxygen consumption and carbon dioxide production and calculated the mechanical power (P(mech)) from two aerodynamic models using wingbeat kinematics measured by high-speed cinematography. P(met) increased from 10.4 to 14.9 W as flight ...
متن کاملHeat transfer from starlings sturnus vulgaris during flight
Infrared thermography was used to measure heat transfer by radiation and the surface temperature of starlings (Sturnus vulgaris) (N=4) flying in a wind tunnel at 6-14 m s-1 and at 15-25 degrees C. Heat transfer by forced convection was calculated from bird surface temperature and biophysical modelling of convective heat transfer coefficients. The legs, head and ventral brachial areas (under the...
متن کاملOn the Estimation of Time Dependent Lift of a European Starling (Sturnus vulgaris) during Flapping Flight
We study the role of unsteady lift in the context of flapping wing bird flight. Both aerodynamicists and biologists have attempted to address this subject, yet it seems that the contribution of unsteady lift still holds many open questions. The current study deals with the estimation of unsteady aerodynamic forces on a freely flying bird through analysis of wingbeat kinematics and near wake flo...
متن کاملWingtip shape and flight performance in the European Starling Sturnus vulgaris
Although wingform is known to differ among individuals of the same species it is not known how intraspecific variation in wingtip shape is associated with flight performance. In this study, we have examined both amongand within-individual variation in wingtip shape in relation to changes in flight performance in the European Starling Sturnus vulgaris . We found that level flapping-flight speed ...
متن کاملNeuromuscular control and kinematics of intermittent flight in the European starling (Sturnus vulgaris)
Electromyographic (EMG) and kinematic data were collected from European starlings (Sturnus vulgaris) flying at a range of speeds from 8 to 18 m s-1 in a variable-speed windtunnel. Their flight at all speeds consisted of alternating flapping and non-flapping phases. Wing postures during non-flapping phases included glides, partial-bounds and bounds. Glides were performed proportionally more ofte...
