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.

シロエリインカハチドリ

コロンビアからボリビアにかけてのアンデス山岳林に生息する中〜大型ハチドリであるエリマキインカハチドリは、幅広の白い胸帯と飛翔時によく見える白い尾斑を持つ、目を引く黒白の羽衣を持ちます。海抜1,700〜3,200メートルの森林と森林縁に生息し、様々な花植物で採食し、アンデスの大型花低木や樹木の重要な花粉媒介者です。対照的な白い尾斑はホバリング飛翔中に目立って点滅し、種の識別を助けます。
