![]() australis' flight speeds fall within the range of other fast-flying molossids such as Tadarida brasiliensis (14.3 m s −1 McCracken et al., 2016) and T. We propose a range of lift and drag coefficient values for use in models of metabolic power output. The frugivore and the carnivore appear to be discrete optimisations while the emballinurid had a long and broad leading edge flap in combination with a high-aspect-ratio tip. ![]() Surface bats were characterised by their low-aspect-ratio wingtips and the absence of optimisations for either low section drag or high lift. The air-superiority bats had leading-edge fences optimised for maximum lift generation while maintaining low drag. The interceptors had the point of maximum camber well forward and no trailing edge wing fences, optimisations for minimum drag generation. Wing relative cleanliness was consistent with, and functionally appropriate to, species foraging strategy. All species assessed had thin, low-camber airfoil sections, an optimisation appropriate to the range of Reynolds Numbers in which bats fly. We present values for bat wing camber (typically 6.5-9%) and its location, measurements of wing planform and tip shape (typically elliptical but with two different tip designs), dimensions of wing leading-edge flaps (typically 8-10.5% of hand wing chord but with some species having much larger flaps up to 18%) and then discuss several features related to airflow separation control. In this paper we examine 12 species of Western Australian bat for anatomical and morphometric attributes related to wing lift and drag characteristics.
