pato-de-crista

<em>Sarkidiornis sylvicola</em>, the South American comb duck, is a large waterfowl in the family Anatidae, assessed as Least Concern on the IUCN Red List. It inhabits tropical and subtropical wetlands, including flooded grasslands, marshes, rivers, and lakes in lowland South America, with occurrence records from Colombia, Venezuela, and associated countries. The species is recognized by the conspicuous knob or comb on the bill of adult males, a secondary sexual characteristic that distinguishes it from the closely related African comb duck (<em>Sarkidiornis melanotos</em>). <em>S. sylvicola</em> is a strong flier that undertakes local seasonal movements in response to water availability and flooding patterns. It nests in tree cavities and forages on aquatic vegetation, seeds, and invertebrates in shallow water and flooded fields. The species maintains a stable population and is not considered threatened.

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.
