Chuuk Flying Fox

The Chuuk flying fox (Pteropus pelagicus) is a large fruit bat in the family Pteropodidae, endemic to Chuuk (Truk) Lagoon in the Federated States of Micronesia, central Pacific Ocean. It occupies forested islands within the lagoon, roosting in large trees and foraging nocturnally on ripe fruits, nectar, and flowers of native tropical vegetation. As one of the few native pollinators and seed dispersers on these small island ecosystems, the Chuuk flying fox plays an essential ecological role in maintaining forest regeneration. The species is classified as Endangered by the IUCN, primarily due to its extremely restricted range—confined to a small island group—and ongoing hunting pressure for bushmeat, which is traditional in parts of Micronesia. Habitat loss from typhoons, agricultural conversion, and human development further threatens its already limited habitat. Pteropus bats across the Pacific have faced severe declines from overhunting, with several island species now extinct. The Chuuk flying fox has a wingspan that can exceed one meter, and roosts colonially in forest canopy trees. International agreements and national legislation within the Federated States of Micronesia provide some protection, but enforcement remains challenging. Population surveys and community-based conservation programs are urgently needed to stabilize this species.
