Roussette Des Îles Chuuk

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.

Roussette de Livingstone

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
