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.

The common haircap, <em>Polytrichum commune</em>, is a moss belonging to the family Polytrichaceae, one of the largest and most structurally complex families within the division Bryophyta. This species is widely distributed across Asia, Europe, North America, and South America, making it one of the most cosmopolitan mosses in the world. <em>Polytrichum commune</em> is typically found in moist to wet habitats including bogs, fens, wet heathlands, and the margins of streams and woodland ponds. It is characterized by its tall, upright gametophytes, which can reach several centimeters in height, and its distinctive star-shaped arrangement of leaves when dry. The species is assessed as Least Concern on the IUCN Red List. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
