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).

Comoros Green-Pigeon

Habitat

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

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.

Comoros Green-Pigeon

<em>Treron griveaudi</em>, the Comoros green pigeon, is a colourful arboreal bird in the family Columbidae endemic to the Comoros islands, particularly Mohéli and Anjouan. Like other members of the genus Treron, it is a frugivorous species adapted to feeding on figs and other small forest fruits in the forest canopy. The species belongs to a diverse Old World pigeon lineage and displays characteristic green and yellow plumage that provides camouflage among leafy forest vegetation. It inhabits tropical moist lowland and montane forest on the Comoros, occupying forest interior and edges where fruiting trees are abundant. The IUCN classifies the Comoros green pigeon as Endangered, reflecting the severe fragmentation and decline of native forests across the islands due to agricultural conversion, logging, and human settlement expansion. The restricted island distribution further limits population resilience and genetic diversity. This species plays an ecological role in seed dispersal, contributing to forest regeneration across its limited range. Biological traits including average body weight, lifespan, and detailed breeding biology remain poorly documented in formal scientific studies. Conservation of the species depends on halting deforestation on Mohéli and Anjouan, where the last significant tracts of native forest persist. Community-based forest protection initiatives remain important for its long-term survival.
