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).

Claw-toothed Salamander

Habitat

Found across multiple habitat types including tropical and subtropical coniferous forests, tropical and subtropical grasslands and savannas, and Mediterranean forests and woodlands, among 6 distinct biome types spanning the Nearctic and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Mexico. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Claw-toothed Salamander

The Claw-Toothed Salamander, Pseudoeurycea cephalica, is a lungless salamander in the family Plethodontidae endemic to the mountains of central Mexico, particularly the Trans-Mexican Volcanic Belt and adjacent highland ranges. As a member of the diverse plethodontid family, it breathes entirely through its moist skin and the lining of its mouth, requiring cool, humid microhabitats beneath rocks, logs, and moist leaf litter on forest floors. The species is relatively slender-bodied, with a long tail and well-developed limbs adapted for life in rocky montane terrain at elevations typically above 2,000 meters. Diet consists of small invertebrates including insects, worms, and arthropods found in the forest floor microhabitat. Reproduction in Pseudoeurycea species typically involves direct development, with eggs laid in moist terrestrial sites hatching as miniature adults rather than aquatic larvae, eliminating the species' dependence on standing water. The highland forests of central Mexico support exceptional salamander diversity, with many species narrowly endemic to individual mountain ranges or even single volcanoes. Deforestation, agricultural expansion, and climate change-driven upslope habitat contraction pose significant threats to highland salamander communities in Mexico. The conservation status of Pseudoeurycea cephalica is assessed as Endangered by IUCN due to ongoing habitat loss.
