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 Eurasian spadefoot toad

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 8 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, Denmark, Luxembourg, Russia, and Sweden. 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.

Common Eurasian spadefoot toad

<em>Pelobates fuscus</em>, the common Eurasian spadefoot toad, is a fossorial amphibian in the family Pelobatidae, listed as Critically Endangered by the IUCN Red List, reflecting severe population declines and an urgent conservation status across its range. The species is documented in Belgium, Denmark, Luxembourg, Russia, and Sweden, and is associated with multiple biome types in the Palearctic region, typically favoring sandy, loose soils in agricultural landscapes, sandy heathlands, and open forests that facilitate its burrowing lifestyle. <em>Pelobates fuscus</em> spends the majority of its life underground, emerging primarily during the breeding season in spring to migrate to shallow, well-vegetated ponds, ditches, and slow-moving waterbodies for reproduction. The species is characterized by its smooth, mottled skin, large golden or yellowish eyes with vertical pupils, and the hardened metatarsal tubercle on each hind foot that serves as a digging tool. Tadpoles of this species are unusually large and can take up to five months to metamorphose. Primary threats include habitat loss through land-use change, drainage of breeding ponds, agricultural intensification, road mortality during migration, and degradation of sandy habitats essential for burrowing. Conservation efforts focus on habitat restoration and the creation of wildlife corridors. Biological traits of this species remain poorly documented in the scientific literature.
