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-mayor

El porrón bastardo (Aythya marila) está clasificado como Vulnerable (VU) en la Lista Roja de la UICN. Enfrenta un alto riesgo de amenaza en estado silvestre, con poblaciones en declive y presión creciente sobre su hábitat.
