Pato crestudo americano

<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.

Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
