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.

The Chocolate-backed Kingfisher (Halcyon badia) is a medium-sized kingfisher in the family Alcedinidae, subfamily Halcyoninae, restricted to the lowland tropical rainforests of West and Central Africa, from Sierra Leone and Ghana east to the Congo Basin. It is one of the forest-dwelling 'tree kingfishers' of the genus Halcyon, which hunt not in aquatic environments but in the dense forest interior, preying on large insects, small lizards, frogs, and other invertebrates taken from branches or the forest floor. The upper parts are a rich, warm chocolate-brown — giving the species its name — contrasting with a bright turquoise-blue rump and tail, and a white or pale buff underside. Like other forest kingfishers, it typically perches silently on a branch and drops onto prey detected from above. Nesting occurs in arboreal termite mounds or rotten tree cavities. The species is dependent on intact lowland rainforest and appears intolerant of heavily degraded or open habitats. The IUCN classifies it as Least Concern given its broad range across the Congo Basin, which still contains large areas of relatively intact forest. Long-term threats include deforestation for agriculture, logging, and charcoal production across its range, particularly in West Africa where forest cover has been severely reduced.
