gavião-cinza

The cinereous harrier (Circus cinereus) is a medium-sized raptor in the family Accipitridae, found across South America, with a breeding range extending from Colombia and Venezuela south through the Andes and adjacent lowlands to Tierra del Fuego and the Falkland Islands. It inhabits open grasslands, marshes, reedbeds, agricultural areas, and the high puna grasslands of the Andes, hunting low over the ground for small birds, rodents, lizards, and frogs. Like other harriers, the cinereous harrier exhibits marked sexual dimorphism: males are pale gray with black wingtips and a white rump, while females are brown and heavily streaked. The species undertakes seasonal migrations, with southern breeding populations moving northward in the austral winter. The cinereous harrier is classified as Least Concern by the IUCN, reflecting its wide South American range and adaptability to a variety of open habitats. It is entirely absent from Europe and occurs nowhere near Norway; database records to the contrary are artifacts. Threats include habitat loss from wetland drainage, conversion of native grasslands to intensive agriculture, and persecution from farmers who incorrectly blame harriers for poultry losses. The species can adapt to agricultural landscapes including rice paddies and open pastures, which provides some buffer against habitat loss.

pinguim-imperador

O maior pinguim do mundo, os pinguins-imperadores medem até 1,2 metro de altura e pesam 45 kg, habitando o continente antártico em algumas das condições mais extremas da Terra. Reproduzem-se no meio do inverno, na escuridão, a temperaturas abaixo de -60°C, com os machos incubando ovos únicos sobre os pés sob uma bolsa de criação por 65 dias enquanto as fêmeas estão no mar. Seu comportamento de aglomeração — onde os indivíduos revezam-se pelo centro quente de grupos de milhares — é uma obra-prima de sobrevivência cooperativa.
