Белоголовый орлан

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.

Серая аулия

The cinereous mourner (Laniocera hypopyrra) is an unusual passerine bird in the family Tityridae, found throughout Amazonia and adjacent parts of northern South America, including Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and the Guianas. It inhabits the interior of humid lowland and foothill forest, typically below 1,000 meters elevation, where it forages at middle and upper heights for large insects and occasional small fruits. The adult is a uniformly gray bird with orange-tipped wing coverts that are only visible at close range or in flight. Remarkable for its mimicry behavior, the nestling of the cinereous mourner closely mimics the coloration and slow swaying movements of the Megalopyge moth caterpillar—a toxic and venomous species—providing protection from predators during the vulnerable nestling stage. This constitutes one of the most striking documented cases of Batesian mimicry in a bird. The species is classified as Least Concern by the IUCN, with a large Amazonian range. It is restricted to South America and does not occur in Europe; Norwegian database records are erroneous. The cinereous mourner is typically seen singly or in pairs, and its secretive habits make it easily overlooked despite its relatively wide distribution.
