Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Cameroon), Asia (Japan, South Korea), Europe (6 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (4 countries). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Golden Eagle

Habitat

Typically found in diverse ecosystems where prey species are available.

Widely distributed across Asia (Taiwan), Europe (6 countries), and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common Silver Hairgrass

<em>Aira caryophyllea</em>, commonly known as Common Silver Hairgrass, is a slender annual grass belonging to the family Poaceae within the order Poales. This delicate grass is currently classified as Endangered on the IUCN Red List, reflecting significant conservation concern despite its historically broad distribution. It is typically found across a remarkable diversity of biome types, including tropical and subtropical moist broadleaf forests, grasslands, savannas, and flooded habitats, demonstrating notable ecological versatility. Its geographic range spans multiple continents, with documented populations in Africa (Cameroon), Asia (Japan, South Korea), Europe, North America, Australia, and South America. As an annual grass, it completes its life cycle within a single growing season, reproducing via wind-dispersed seeds. The inflorescence typically bears silvery, shimmering spikelets that give the species its common name. Biological traits such as average lifespan, body dimensions, and dietary specifics follow typical patterns for annual grasses — drawing nutrients from soil through root absorption rather than consuming other organisms. The endangered status suggests populations may be declining due to habitat loss, land-use change, or invasive species pressure across parts of its range.

Golden Eagle

세계에서 가장 강력하고 널리 분포하는 맹금류 중 하나인 검독수리는 날개 폭이 2.2m에 달하며 북반구 전역의 산악 지형에 서식한다. 뛰어난 공중 사냥꾼으로 활공 비행과 시속 200km 이상의 가파른 강하를 이용해 토끼, 산토끼, 땅다람쥐, 때로는 어린 사슴과 여우를 포획한다. 많은 문화권에서 수천 년에 걸친 매사냥 전통의 중심에 있어 왔다.
