Habitat & Geographic Range

白头海雕

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).

Colorado Pinyon

Habitat

Typically found in temperate and boreal forests, often at higher elevations.

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。

Colorado Pinyon

<em>Pinus edulis</em>, the Colorado pinyon or two-needle pinyon pine, is a small to medium-sized conifer in the family Pinaceae forming an integral component of pinyon-juniper woodland ecosystems across the southwestern United States. This species is assessed as Least Concern by the IUCN. It inhabits temperate and boreal forest zones at higher elevations, typically between 1,500 and 2,700 metres, on rocky, well-drained soils in arid and semi-arid mountain ranges. The large, wingless seeds of <em>Pinus edulis</em>, commonly known as pine nuts, are an important food source for a diversity of wildlife including jays, woodpeckers, squirrels, and bears, as well as for Indigenous peoples of the American Southwest who have harvested them for millennia. Pinyon jays in particular exhibit strong ecological mutualism with this pine, caching seeds and inadvertently dispersing them across the landscape. The species is susceptible to bark beetle outbreaks during drought conditions, and large-scale tree mortality events have been recorded during extended droughts in recent decades. Biological traits of this species remain poorly documented in the scientific literature.
