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。

Common Awl Robberfly

<em>Neoitamus cyanurus</em>, commonly known as the Common Awl Robberfly, is a predatory dipteran insect in the family Asilidae. This species is classified as Least Concern on the IUCN Red List and is distributed across northern and western Europe, including Belgium, Denmark, Norway, and Sweden. Like all robber flies, the Common Awl Robberfly is an active aerial predator that captures other flying insects in mid-flight, using its strong legs and piercing mouthparts to subdue and consume prey. Adults typically frequent open and semi-open habitats such as forest clearings, heathlands, and sunny woodland edges where prey insects are abundant. The larvae are believed to develop in soil or decaying wood, where they feed on other invertebrate larvae. Adults are typically observed perching on bare ground or low vegetation, from which they launch short, rapid flights to intercept passing prey. Their robust build, bristly body, and forward-pointing beak are characteristic features of the Asilidae family. Biological traits of this species remain poorly documented in the scientific literature.
