pigargo-americano
A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.
Cinnamon-bellied Ground-Tyrant
The cinnamon-bellied ground tyrant (Muscisaxicola capistratus) is a small flycatcher in the family Tyrannidae, found in the arid steppe, puna grasslands, and rocky slopes of western and central Argentina and Bolivia. It inhabits open, barren, and semi-arid environments at elevations from approximately 2,000 to 4,500 meters in the eastern Andes foothills and Patagonian steppe, foraging on the ground for insects and small invertebrates. The plumage is brown above with a distinctive rufous-cinnamon belly that contrasts with paler underparts, giving the species its common name. Like other ground tyrants in the genus Muscisaxicola, it runs and pauses across bare or sparsely vegetated ground rather than perching on vegetation. The species is classified as Least Concern by the IUCN, with a restricted but apparently stable South American range. Ground tyrants as a group represent a highly successful Andean radiation into open, high-altitude habitats. This species is entirely absent from Europe; any database record associating it with Norway is a data artifact. Threats include overgrazing of native steppe vegetation by livestock, which can degrade foraging habitat, and climate-driven changes in Andean precipitation and vegetation cover.
