Large Flying-fox (Pteropus vampyrus) lives in tropical rainforest across Southeast Asia. It feeds on nectar and fruit. Its conservation status is Endangered.
Fascinating facts about the Large Flying-fox
- Its wingspan can reach up to 1.5 m (4 ft 11 in). That size pairs with a body that tips the scales at 0.65-1.1 kg (1.4-2.4 lb), making it one of the biggest bats on Earth. Its massive wings are short and rounded, giving it slow but highly maneuverable flight, crucial for navigating dense forest canopies while foraging on fruit and nectar. This sheer size lets the bat carry heavy food loads and disperse seeds over long distances, shaping tropical forest regeneration.
- These bats can travel up to 50 km (31 mi) in a single night to reach feeding sites. Such nightly journeys let them exploit scattered fruiting trees, especially coconut, durian, and fig. By moving far and repeatedly, they spread seeds across vast areas, linking fragmented habitats and boosting forest connectivity.
- A single colony can swell to tens of thousands of individuals; one mangrove roost in Timor held around 2,000 bats, while other sites have reported 10,000-20,000. Such massive gatherings create noisy, noisy feeding aggregations. The sheer number of foragers amplifies their role as seed dispersers.
- Despite being called a "vampire" bat, it never drinks blood; its diet is 100 % plant-based, favoring flowers and nectar when all three food types are present. This preference for nectar means the bat can sip coconut and durian blossoms without harming the flower, acting as a pollinator for high-value crops. Their pollination helps sustain both wild forest trees and commercially important fruit trees.
- Legal hunting in Peninsular Malaysia once allowed 87,800 bats to be killed over five years, about 22,000 each year, far exceeding sustainable limits. Modeling predicts that at that rate the regional population could vanish in as few as 6 years or up to 81 years, underscoring how current harvest levels threaten the species' survival.
