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。

嘰咋栗額鵙鶥

The Clicking Shrike-babbler, Pteruthius intermedius, is a small, chunky passerine bird in the family Vireonidae found in the montane forests of Southeast Asia and the eastern Himalayas, ranging from northeastern India and Bhutan through Myanmar, northern Thailand, Laos, Vietnam, and southern China. The species inhabits subtropical and temperate broadleaf montane forests at elevations generally between 1,500 and 3,000 meters, where it forages actively in the forest canopy and mid-story for insects, larvae, and small berries. Males display striking plumage with a gray head, rufous flanks, and a white wing patch, while females are more cryptically colored in olive and buff. The name 'clicking' refers to the species' characteristic vocalizations, including sharp clicking and chattering calls used in territorial defense and pair communication. Pteruthius intermedius is typically encountered in pairs or small groups and regularly joins mixed-species bird flocks that forage through the forest interior, a common foraging strategy in diverse Asian montane bird communities. Montane forest birds of Southeast Asia face increasing pressure from deforestation, agricultural encroachment at forest margins, and climate-driven upslope habitat contraction. The species is currently assessed as Least Concern by IUCN.
