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.

<em>Erucastrum gallicum</em>, the common dogmustard, is an annual or biennial herb in the family Brassicaceae. This species has a broad distribution across Asia, Europe, and North America, with records from Japan, twenty-four European countries, Canada, Mexico, and the United States. It typically inhabits disturbed terrestrial environments such as roadsides, waste ground, agricultural margins, and rocky or sandy soils. Common dogmustard is characterized by its deeply lobed leaves, slender branching stems, and small pale yellow four-petaled flowers arranged in elongated racemes. The plant generally grows to 20–60 centimeters in height and produces narrow silique seed pods that split open at maturity to release small brown seeds. <em>Erucastrum gallicum</em> often thrives in nutrient-poor, well-drained soils and is considered a weed in some agricultural regions. Biological traits of this species remain relatively poorly documented in detail beyond basic morphological and distributional data available in the scientific literature.
