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。

顫鳴扇尾鶯

The churring cisticola (Cisticola njombe) is a small insectivorous warbler in the family Cisticolidae, endemic to the highlands of East Africa. It inhabits montane grasslands, bracken-fern slopes, and the margins of high-altitude forest patches, primarily in the Nyika Plateau, the Njombe highlands of southern Tanzania, and adjacent areas of Malawi and Zambia. The species occupies elevations typically between 1,500 and 2,500 meters, where it forages low in dense grass and sedge clumps, gleaning insects and small invertebrates. The churring cisticola is named for its distinctive mechanical churring song, which males produce from low perches or during short display flights. It is a compact, streaked brown bird with a rufous-washed tail and pale underparts, closely resembling related montane cisticolas. The species is classified as Least Concern by the IUCN, with populations considered stable across its restricted highland range. Like other afromontane endemics, it depends on the persistence of intact highland grassland ecosystems, which face ongoing threats from agricultural encroachment, fire management changes, and human settlement. Taxonomic relationships within the Cisticola genus are complex, and the njombe cisticola has been subject to periodic revision. Conservation of afromontane grasslands in Tanzania and Malawi is critical for this and many co-occurring endemic species.
