Gliding behavior of Japanese giant flying squirrels, Petaurista leucogenys, was studied at Nara Park, Japan. We observed 150 glides. We were able to calculate glide ratios on 57 glides and airspeeds on 29 glides. Glide ratios (distance/[altitude lost]) averaged 1.87, and a glide ratio of 3–3.5 seems to represent an upper performance limit for P. leucogenys. Airspeeds (4.39–9.47 m/s) were substantially lower than reported in other studies, and glide angles were higher (17.74–34.99°). Aspect ratios of the animals in mid-glide averaged 1.42.
