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.

Oxalide d'Europe

<em>Oxalis stricta</em>, the common yellow oxalis or upright yellow wood sorrel, is an annual or perennial herbaceous plant in the family Oxalidaceae. It is native to North America but has been widely naturalized across Europe, Asia, Australia, and other temperate regions, where it occurs as a common weed of gardens, cultivated land, roadsides, and disturbed ground. The plant typically grows 10–40 cm tall and produces trifoliate clover-like leaves with three heart-shaped leaflets that fold downward at night or under bright sunlight, a response known as nyctinasty. Bright yellow five-petaled flowers are borne on slender stalks from spring through autumn. Seed pods explode at maturity to disperse seeds over short distances, contributing to the plant's effectiveness as a colonizer. Biological traits such as precise average lifespan and body measurements remain poorly documented in consolidated literature. <em>Oxalis stricta</em> contains oxalic acid, which gives the plant a sour taste and can be mildly toxic to livestock in large quantities. It provides nectar for small pollinators. The species has not been formally evaluated for IUCN conservation status but is abundant and widespread globally, with no conservation concerns.
