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.

Géospize des cactus

<em>Geospiza scandens</em>, commonly known as the common cactus finch, is a bird species found in Ecuador and with records from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often closely associated with arid island ecosystems where cacti are prevalent. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. The common cactus finch belongs to the genus <em>Geospiza</em> within the family Thraupidae and is among the iconic Darwin's finches of the Galápagos Islands. It typically feeds on the nectar, pollen, and seeds of cactus plants, particularly <em>Opuntia</em>, and plays an important role as a pollinator and seed disperser within its island habitat. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Population trends are considered stable, and the species remains an important subject of evolutionary and ecological research.
