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.

Cocha Antshrike

The cocha antshrike (Thamnophilus praecox) is a poorly known, range-restricted bird in the family Thamnophilidae—the antbirds—endemic to a narrow strip of floodplain forest along the lower Napo River drainage in northeastern Ecuador and immediately adjacent northern Peru. The species is strongly associated with dense, shrubby vegetation in seasonally or permanently flooded várzea and igapó forests, particularly thickets of Gynerium sugarcane and other tall grasses and shrubs at the forest-water interface in oxbow lakes and riverine backwaters—habitats reflected in its name, 'cocha' being a Quechua word for lagoon or lake. Males display the typical antshrike pattern of bold black and white barring on the wings and mantle, with a black crown and white underparts; females are rufous-brown above with streaked underparts, providing camouflage in dense vegetation. The cocha antshrike feeds by gleaning insects and other arthropods from low vegetation within its flooded forest thickets, foraging in pairs or small groups year-round within apparently stable territories. Its highly specialized and fragmented habitat makes the species particularly vulnerable to deforestation, petroleum extraction activities, and hydrological alteration of Amazonian floodplain systems. Classified as Near Threatened by the IUCN, the cocha antshrike faces ongoing threats from habitat loss within its extremely restricted range, and comprehensive population surveys remain a research priority.
