Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

サントメアサギリチョウ

The Cinderella waxbill (Estrilda thomensis) is a small passerine bird in the family Estrildidae, endemic to São Tomé Island in the Gulf of Guinea, off the western coast of Central Africa. It inhabits forest edges, secondary growth, gardens, and cultivated areas with dense low vegetation, where it forages for grass seeds and small invertebrates, typically in small flocks. The species shares its common name with its delicate, finely patterned plumage featuring a gray crown, red bill, dark mask, and rusty-pink flanks, suggesting an ornate appearance reminiscent of the fairy tale character. The Cinderella waxbill is classified as Least Concern by the IUCN, with populations considered stable on São Tomé, where it is one of the more commonly encountered endemic birds in modified habitats. São Tomé and Príncipe together represent one of Africa's most important island biodiversity hotspots, with remarkable levels of avian endemism resulting from long isolation. The island's endemic waxbill benefits from its adaptability to secondary and garden habitats, tolerating a degree of human land use. Conservation of remaining native forest on São Tomé is critical for the many forest-dependent endemic species on the island. The species is occasionally kept by aviculturalists but is not a major target of the wild bird trade.
