Fig. 7. Scatter plot showing how the glide angle increases with horizontal range until it reaches approximately 45°, represented by a broken line, after which the glide ratio begins to improve slightly. High take-off angles and limited time spent in the air are the factors responsible for the low vales of glide angle across low ranges. Glide angle is strongly negatively correlated with range above 4 m (r=–0.816, P<0.001) where higher glide speeds enable northern flying squirrels to exhibit superior lift to drag ratios.
