Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Cluster Fescue

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Found in United States.

American Bald Eagle

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.

Cluster Fescue

Cluster fescue, known scientifically as Festuca paradoxa, is a perennial bunchgrass in the family Poaceae that holds the tragic distinction of being Extinct. Endemic to the central and eastern United States, this grass once inhabited moist, shaded woodland edges, floodplain forests, and riverbank communities where it formed discrete clumps characteristic of caespitose fescues. Festuca paradoxa was a slender, cool-season grass reaching approximately 60–120 centimeters in height, with flat or loosely rolled leaf blades and an open panicle inflorescence. It was associated with rich bottomland soils where periodic flooding maintained the open canopy conditions it required. The species declined catastrophically due to the widespread destruction of floodplain woodlands across its range through agricultural conversion, wetland drainage, and urban development over the nineteenth and twentieth centuries. Invasive species competition and altered hydrological regimes further compressed suitable habitat. The genus Festuca contains hundreds of species distributed globally in temperate and montane regions, but F. paradoxa occupied a narrow ecological niche that proved impossible to sustain amid large-scale landscape transformation. Its extinction represents a permanent loss from North American grassland diversity, and no living populations are known to persist anywhere in its former range.
