Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.

ハイバラエメラルドハチドリ

アカオハチドリ(Amazilia tzacatl)は中央アメリカと南アメリカ北西部で最もよく見られるハチドリの一つで、緑色の上面と診断的な明るい赤褐色の尾が特徴的な中型種である。メキシコからエクアドル、トリニダードにかけて、海抜0~2,100mの林縁、庭園、農園、二次林など多様な環境に生息する。給餌台や花の咲く植物の縄張りを積極的に守り、分布域全体の庭でしばしば目撃される。軽度懸念に指定されている。
