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 Newtonia

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway.

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 Newtonia

<em>Newtonia brunneicauda</em>, the common newtonia, is a small passerine bird in the family Vangidae, endemic to the island of Madagascar. This insectivorous bird typically inhabits humid and subhumid forests, forest edges, and secondary vegetation in the eastern and northern parts of Madagascar. <em>Newtonia brunneicauda</em> forages actively in the mid-storey and understorey, gleaning insects and other small invertebrates from foliage and branches. Its geographic range is largely restricted to Madagascar, though occurrence data in the source records lists Norway, which may reflect a sampling artifact rather than the species' actual distribution. The species is currently assessed as Least Concern by the IUCN, with populations considered relatively stable despite ongoing forest loss in Madagascar. Biological traits such as lifespan, body size, and diet remain poorly documented at a population level for this species. The common newtonia is a characteristic component of Madagascar's endemic forest bird community and is considered an indicator of relatively intact forest habitat. Its conservation is linked to the preservation of Madagascar's remaining tropical forests, which face significant pressure from slash-and-burn agriculture and timber extraction.
