Colimbo mayor

<em>Gavia immer</em>, the common loon or great northern diver, is a large aquatic bird in the family Gaviidae, known for its haunting, yodeling calls across northern lakes. It is found in Belgium, Denmark, Norway, Sweden, and the United States, breeding on freshwater lakes in boreal and subarctic regions and wintering along marine coastlines. The common loon is adept in aerial, terrestrial, and aquatic environments, though it is most highly specialized for diving, using its strong feet positioned far back on its body to pursue fish underwater. It typically feeds on fish, supplemented by crustaceans and aquatic invertebrates. Its striking summer plumage features a black-and-white checkered back and a deep black head with a characteristic white necklace pattern. The species has not been evaluated for IUCN conservation status. Common loons require clear, fish-rich lakes for successful breeding and are sensitive to water quality degradation and human disturbance at nesting sites. Their distinctive calls are emblematic of wilderness in North America and Scandinavia.

León

El felino salvaje más grande de Africa, el león puede alcanzar hasta 250 kg y es el único félido social, viviendo en manadas en sabanas y praderas del Africa subsahariana. Los machos se distinguen por sus icónicas melenas. Como depredadores apicales, regulan las poblaciones de herbívoros y mantienen el equilibrio del ecosistema. Clasificado como Vulnerable debido a la pérdida de hábitat y el conflicto entre humanos y vida silvestre.
