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。

Clay's Hibiscus

Clay's Hibiscus, Hibiscus clayi, is a rare flowering shrub in the family Malvaceae endemic to the island of Kauai in the Hawaiian archipelago. It is one of the native Hawaiian hibiscus species belonging to the kokio group, characterized by brilliantly colored flowers adapted to pollination by native Hawaiian honeycreepers, which probe the tubular flowers for nectar. Hibiscus clayi produces large, vivid red to orange-red flowers with five overlapping petals surrounding a prominent staminal column, typical of the hibiscus form. The shrub grows in dry to mesic forest habitats at low to moderate elevations on Kauai, where it is associated with native Hawaiian dryland forest communities. Like many Hawaiian plants, Clay's Hibiscus evolved in near-total isolation and is adapted to a unique ecological community that has been severely disrupted by the introduction of non-native species, habitat conversion, and the decline of native pollinators. The species is critically threatened by habitat loss, competition from invasive plants, and the extinction of native Hawaiian honeycreeper pollinators due to introduced avian malaria. Hibiscus clayi is listed as Endangered and is the subject of conservation efforts including propagation in botanical gardens and habitat restoration projects on Kauai.
