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.

carex commun

<em>Carex communis</em>, the colonial oak sedge, is a perennial sedge in the family Cyperaceae occurring in Sweden and the United States. This species has not been evaluated by the IUCN. It typically forms tufted clumps in shaded woodland habitats, particularly beneath deciduous oak and mixed hardwood forest canopies, where it tolerates low light conditions and well-drained acidic soils. Colonial oak sedge occupies grasslands, wetlands, temperate forests, and cultivated landscapes, suggesting moderate habitat breadth within its range. As a member of the large and ecologically diverse genus <em>Carex</em>, this species plays a role in woodland ground-layer communities, providing microhabitat structure for invertebrates and small mammals. Sedges in general are important components of cool temperate ecosystems, contributing to soil stabilisation and organic matter cycling. <em>Carex communis</em> is wind-pollinated and reproduces both vegetatively through rhizome extension and sexually through seed production. Biological traits of this species remain poorly documented in the scientific literature.
