コモロウロコツグミ

<em>Turdus bewsheri</em>, the Comoro thrush, is a medium-sized passerine bird in the family Turdidae endemic to the Comoros archipelago, occurring across Grande Comore, Anjouan, and Mohéli islands. It belongs to the cosmopolitan thrush genus Turdus, which contains over 80 species distributed worldwide. The Comoro thrush inhabits forests and woodland edges across a range of elevations on the islands, from lowland coastal areas to montane forest zones. Like other true thrushes, it is an omnivore typically feeding on invertebrates, berries, and small fruits found in leaf litter and forest understory. The species is classified as Near Threatened by the IUCN, indicating that while not yet considered at immediate risk, ongoing habitat degradation and deforestation across the Comoros pose long-term concerns. Forest clearance for subsistence agriculture and charcoal production continues to reduce suitable habitat across all three islands. The Comoro thrush is generally considered relatively adaptable compared to more specialist endemics, tolerating some degree of forest degradation. However, continued habitat loss could elevate its threat status in future assessments. Biological traits including precise body measurements, lifespan, and clutch size data remain poorly documented compared to continental thrush species. Its melodic song is a characteristic feature of Comoran forest soundscapes.

アオフタオハチドリ

ナガオシルフハチドリ(Aglaiocercus kingii)は最も鮮やかに装飾されたハチドリの一つで、雄は虹色の緑色羽毛と22cmに達するリボン状に長く伸びた外側尾羽を持ち、これは体長の3倍を超える。コロンビアとベネズエラのアンデス雲霧林の標高1,400〜2,800mに生息し、雄は雌を引き付けるために精巧な誇示飛行を行う。その華麗な尾羽は、雌の選好による性的選択の古典的な例である。
