ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

common brown lemur

The common brown lemur (<em>Eulemur fulvus</em>) is a medium-sized primate endemic to Madagascar, typically inhabiting diverse terrestrial and aquatic environments including tropical moist forests. This species is classified as Vulnerable on the IUCN Red List, reflecting significant population declines driven primarily by habitat loss and fragmentation resulting from deforestation and land conversion across its native range. As a member of the family Lemuridae, the common brown lemur is characterized by its brown to gray fur, pale face patches, and social group-living behavior. The species is typically diurnal and cathemeral, meaning it may be active during both day and night depending on season and conditions. It often feeds on fruits, leaves, flowers, and invertebrates, making it an important seed disperser in Malagasy forest ecosystems. The common brown lemur typically lives in social groups ranging in size from a few individuals to over a dozen animals. Biological traits of this species remain poorly documented in the scientific literature.
