Habitat & Geographic Range

Pygargue à tête blanche

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).

Chrome-Footed Bolete

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Norway and United States.

Pygargue à tête blanche

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.

Chrome-Footed Bolete

The chrome-footed bolete (Xerocomus chrysenteron), sometimes treated as synonymous with Boletus chrysenteron, is a bolete mushroom in the family Boletaceae or Xerocomaceae, depending on the classification system applied. The genus Xerocomus has been subject to significant taxonomic revision in recent decades as molecular phylogenetic analyses have reshaped the boundaries of bolete genera. Species in Xerocomus are generally characterized by dry, often velvety caps, yellow to reddish stipes, and a tendency for cut flesh to stain blue. They form ectomycorrhizal relationships with deciduous and coniferous trees, contributing to the nutrient and water uptake capacity of their host trees. Xerocomus chrysenteron is found in temperate forests of Europe and has been recorded in similar forest types elsewhere, fruiting in summer and autumn. The cap often develops characteristic cracks revealing reddish flesh beneath an olive-brown surface. While edible, the species is considered inferior in quality to many other boletes, with soft flesh that deteriorates quickly. It is common and widespread with no conservation concerns of note. Taxonomic uncertainty surrounding the species complex has led to some confusion in identification, and multiple closely related species are now recognized within the broader Xerocomus group.
