白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

大科摩羅角鴞

<em>Otus pauliani</em>, the Comoro scops owl, is a critically small nocturnal raptor in the family Strigidae, endemic to Mount Karthala on Grande Comore island in the Comoros archipelago. This species is one of the world's most geographically restricted owls, confined to a single volcano's upper montane forests above approximately 1,000 metres elevation. It belongs to the diverse Otus scops owl complex widespread across Africa and Asia, with island forms often evolving in isolation. The Comoro scops owl inhabits dense montane forest and heath zones dominated by native tree species. Its cryptic plumage provides excellent camouflage among bark and foliage. The IUCN lists it as Endangered due to its extremely small range, estimated tiny population, and ongoing loss of montane forest habitat from agricultural encroachment and periodic eruptions from Karthala. Like other scops owls, it is presumed to be insectivorous, hunting invertebrates nocturnally, though specific dietary data remain limited. Biological traits including body mass, lifespan, and detailed morphometrics remain poorly documented for this species. Conservation is particularly challenging given the species' restriction to a single active volcanic mountain, making the entire population vulnerable to a single catastrophic event. Protecting the remaining montane forest belt on Grande Comore is the primary conservation priority for this owl.
