흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

Cinereous Ground-Tyrant

The cinereous ground tyrant (Muscisaxicola cinereus) is a small flycatcher in the family Tyrannidae, found in the high Andes and Patagonian grasslands of South America, with a range spanning Chile, Argentina, Bolivia, and Peru. It inhabits open, barren, or sparsely vegetated habitats such as high-altitude puna grassland, rocky Andean plateaus, rocky coastal grassland, and steppe vegetation, typically at elevations from 1,000 meters to above 4,500 meters. Like other ground tyrants, it forages on the ground for insects and small invertebrates, often running and pausing rather than perching. The plumage is uniform gray to brownish-gray with a slightly paler underside. The cinereous ground tyrant is classified as Least Concern by the IUCN, with a wide South American range and stable populations. Ground tyrants of the genus Muscisaxicola represent a fascinating adaptive radiation into high-altitude open habitats across the Andes and southern South America. This species is entirely restricted to South America and is absent from Europe; any database record citing Norway is incorrect. Andean grassland habitats face increasing pressure from overgrazing, burning, and climate-driven changes in vegetation, but the cinereous ground tyrant's wide range and tolerance of degraded habitats suggest resilience.
