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 Birdwing

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

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 Birdwing

The common birdwing (<em>Troides helena</em>) is a large and striking butterfly of the family Papilionidae, classified as Least Concern on the IUCN Red List. It inhabits terrestrial and freshwater environments across its range in South and Southeast Asia. <em>Troides helena</em> is among the larger birdwing butterflies, with males displaying vivid yellow and black coloration on the hindwings, while females are typically larger and more cryptically marked. The species is often found in tropical and subtropical forest habitats, where it visits flowering plants for nectar. Larvae of birdwing butterflies typically feed on Aristolochia vines, which contain toxic alkaloids that are sequestered by the caterpillars and retained in adult tissues as a chemical defense. Despite its Least Concern status, birdwing butterflies are subject to trade regulations due to their attractiveness to collectors. Biological traits of this species remain poorly documented in the scientific literature.
