Weißkopf-Seeadler

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.

Scharfer Hahnenfuss

<em>Ranunculus acris</em>, commonly known as the common buttercup, is a widely distributed plant species found across Asia, Europe, North America, and Oceania. It typically thrives in diverse terrestrial habitats, often colonizing meadows, pastures, roadsides, and disturbed ground with moist, well-drained soils. The species is classified as Least Concern on the IUCN Red List, reflecting its broad range and generally stable populations. Common buttercup belongs to the genus <em>Ranunculus</em> within the family Ranunculaceae. It is a perennial herbaceous plant that typically produces distinctive bright yellow, glossy petals and is commonly associated with temperate grassland ecosystems. The species is known to contain toxic alkaloids, making it generally unpalatable to livestock when fresh, though it loses toxicity upon drying. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Its cosmopolitan distribution across multiple continents underscores its ecological versatility and its ability to colonize a wide variety of environments.
