Reproductive characteristics of red-giant flying squirrels ( Petauristapetaurista ) were studied from December 1981 to November 1982 in Taiwan. We collected 216 adults (116 males, 100 females) and 65 immatures (23 males, 42 females). The sex ratio of adults did not deviate from 1:1 ratio ( P > 0.05). Adult females tended to be heavier than adult males (1,334 and 1,260 g, respectively, P 56 g. This species is a seasonal breeder with low reproductive rates, which may be a result of a low predation rate combined with their high degree of folivory.
