The aerodynamic effect of the furled avian tail on the parasite drag of a bird's body was investigated on mounted, frozen European starling Sturnus vulgaris in a wind tunnel at flight speeds between 6 and 14 m s(-1). Removal of tail rectrices and dorsal and ventral covert feathers at the base of the tail increased the total parasite drag of the body and tail by between 25 and 55%. Flow visualization and measurements of dynamic pressure in the tail boundary layer showed that in the intact bird a… CONTINUE READING
