The effect of daytime rain on the Indian Flying Fox (Mammalia: Chiroptera: Pteropodidae Pteropus giganteus)

Main Article Content
Abstract
Excessive water loss during the day due to heat stress in bats of the genus Pteropus appears to be inevitable, because these bats are exposed to direct sunlight. Rain also affects the rest pattern of the Indian Flying Fox Pteropus giganteus during the day. When rain occurred during the day, most of the bats hung in a slanting position and did not exhibit any movements. After rain, they licked both ventral and dorsal surfaces of the wing membrane and scratched their body with their thumb claws. They also licked the water droplets that remained on the leaves and branches of the tree. Even though their rest had been affected by the rain the bats utilized the water droplets to quench their thirst, cool their body and clean their fur. The construction of water reservoirs near Pteropus roosts will help to assure their long-term conservation.
