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).

Cock's-spur

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

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.

Cock's-spur

The cock's spur (Erythrina eggersii) is a small to medium-sized deciduous tree in the family Fabaceae, classified as Endangered and endemic to the Caribbean region, with its range restricted to a limited number of eastern Caribbean islands. Like other members of the genus Erythrina — the coral trees — it produces large, vivid red flowers that are a primary nectar source for hummingbirds and other nectarivorous birds, which serve as the tree's principal pollinators. The common name refers to the spurred or claw-shaped petals of the flower, characteristic of the genus. Erythrina eggersii is threatened primarily by habitat loss through agricultural conversion, development, introduced herbivores including goats and cattle that browse regenerating seedlings, and the extreme vulnerability of island endemic species to stochastic events such as hurricanes and droughts. The restricted range, small total population, and ongoing habitat decline place this species squarely in the Endangered category under IUCN criteria. Caribbean islands support disproportionately high levels of plant endemism but also suffer from among the highest rates of habitat conversion and invasive species pressure of any region globally. Conservation priorities for E. eggersii include protection of remaining native dry forest fragments, control of invasive herbivores, and ex situ cultivation as insurance against further population decline. The species was named for the Danish botanist Hans Franz Alexander von Eggers, who collected extensively in the Caribbean during the nineteenth century.
