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.

Common blowfly

The common blowfly (<em>Calliphora grahami</em>) is a fly species found across the United States, typically inhabiting all terrestrial and freshwater environments. As a member of the family Calliphoridae, this species often plays an important ecological role as a decomposer and pollinator across its range. The common blowfly is classified as Least Concern on the IUCN Red List, indicating a stable population with no immediate threat of extinction. Its diet includes decaying organic matter, making it a significant contributor to nutrient cycling in its native habitats. The species is commonly associated with a wide variety of terrestrial ecosystems, from open grasslands to forested areas, and is often found near human settlements. Biological traits of this species remain poorly documented in the scientific literature.
