African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

コロンビアヒメクイナ

Neocrex colombiana, commonly known as the Colombian Crake, is a bird species belonging to the genus Neocrex within the family Rallidae, a group of typically secretive marsh and wetland birds. This species is classified as Data Deficient, indicating that current information is insufficient to accurately determine its conservation status, and that further survey work is required to understand its population size and trend. It has been documented in Colombia and Ecuador, where it inhabits various environmental settings consistent with rallid ecology, including wetlands, marshy grasslands, and dense vegetation near water. Rails and crakes in this family are generally omnivorous, feeding on invertebrates, seeds, and small vertebrates, though specific dietary records for this species have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The secretive nature of rallid birds, combined with their preference for dense habitats, makes population surveys challenging. Comprehensive field surveys using acoustic monitoring are considered essential for improving knowledge of Neocrex colombiana.
