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 blowfly

The common blowfly (<em>Calliphora grahami</em>) is a fly species found across the United States, typically inhabiting all terrestrial and freshwater environments. As a member of the family Calliphoridae, this species often plays an important ecological role as a decomposer and pollinator across its range. The common blowfly is classified as Least Concern on the IUCN Red List, indicating a stable population with no immediate threat of extinction. Its diet includes decaying organic matter, making it a significant contributor to nutrient cycling in its native habitats. The species is commonly associated with a wide variety of terrestrial ecosystems, from open grasslands to forested areas, and is often found near human settlements. Biological traits of this species remain poorly documented in the scientific literature.
