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.

Pato boludo-menor

La Porrón Menor (Aythya affinis) está clasificado como Preocupación Menor (LC) en la Lista Roja de la UICN. Es una especie amplia y abundante en su área de distribución, con poblaciones estables y sin preocupaciones de conservación inmediatas.
