Comoro Flying Fox

<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.

ブンチョウ

東アジアで最も人気のある飼い鳥の一つであるジャワスズメは、灰色の羽毛、鮮やかな黒い頭部、特徴的な白い頬斑、明るい赤いくちばしを持つ印象的なフィンチである。インドネシアのジャワ島とバリ島が原産地で、アジア・アフリカ・アメリカの多くの地域に導入されている。開けた草地、水田、農地に生息し、稲作に被害を与えることがある。籠鳥取引のための深刻な捕獲圧力により、原産地では絶滅危惧種に指定されている。
