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.

Pseudoperonospora urticae is an obligate biotrophic oomycete downy mildew pathogen in the family Peronosporaceae, infecting stinging nettle (Urtica) species. It causes yellowing and chlorosis of leaves with characteristic grayish sporulation on the undersurface during moist conditions. Its host specificity to nettles makes it an interesting model for studying coevolution between oomycete pathogens and their wild hosts.
