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 Orange Lichen

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, Portugal, Sweden, and United States.

American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Common Orange Lichen

<em>Xanthoria parietina</em> is a foliose lichen in the family Teloschistaceae, one of the most conspicuous and widely recognized lichens across Europe and North America. It is recorded in Denmark, Norway, Portugal, Sweden, and the United States. The species typically colonizes bark, rock surfaces, walls, roof tiles, and other exposed substrates in nutrient-enriched environments. Its vivid orange to yellow-orange thallus is produced by the pigment parietin, which functions as a photoprotective compound shielding the lichen from UV radiation. <em>Xanthoria parietina</em> is considered a nitrophilous species, thriving in habitats enriched by nitrogen compounds, such as those near bird roosting sites, agricultural areas, and urban zones. It is highly tolerant of air pollution and is frequently used as a bioindicator in ecological studies. The IUCN lists this species as Least Concern given its broad distribution and tolerance of disturbed environments. As a lichen, it is a mutualistic association between a fungal partner and algal or cyanobacterial photobionts. Biological traits such as growth rates, lifespan, and dietary ecology remain poorly documented in standardized databases for lichen species.
