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).

Common Bird'S Nest

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (Norway, Portugal, Sweden), North America (United States), and South America (Brazil).

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.

Common Bird'S Nest

The common bird's nest (<em>Crucibulum laeve</em>) is a small cup-shaped fungus belonging to the family Nidulariaceae, known for its distinctive nest-like fruiting bodies that contain egg-like spore packages called peridioles. It is classified as Least Concern on the IUCN Red List. The species has been documented in Taiwan, Norway, Portugal, Sweden, the United States, and Brazil, reflecting a wide global distribution. <em>Crucibulum laeve</em> typically grows on decaying wood, forest floors, and decomposing organic material, where it plays a role in breaking down cellulose-rich substrates. The funnel-shaped cups, often pale tan in color, are designed to use splashing raindrops as a dispersal mechanism, propelling the peridioles outward to deposit spores on new substrates. This splash-cup dispersal strategy is a distinctive adaptation shared among bird's nest fungi. Biological traits of this species remain poorly documented in the scientific literature.
