Knowledge of the gliding performance of gliding mammals provides important insight into how these species have evolved to use their environment but it can also be used to guide tree retention and habitat restoration. We investigated the glide performance of the inland sugar glider (Petaurus notatus) in central Victoria. We measured 40 glides from untagged individuals during nest box monitoring. On average, gliders launched into a glide from a height of 14.7 m above the ground and landed at 6.2 m above the ground. The average horizontal glide distance was 18.1 m (range 8–41 m). The glide ratio (horizontal glide distance/height dropped) and glide angle averaged 2.2 and 26.4°, respectively. These values represent a better average glide performance than any previously measured for an Australian gliding mammal. These data are contrasted with those of other gliding mammals to explore the hypothesis that smaller species may be more capable gliders than larger related species. Understanding glide performance in gliding mammals provides useful knowledge. We investigated this in the inland sugar glider (Petaurus notatus) in central Victoria. From 40 glides, horizontal glide distance averaged 18.1 m (range 8–41 m), glide ratio (horizontal glide distance/height dropped) averaged 2.2 and glide angle averaged 26.4°.
