Common Raven

One of the most intelligent birds known, common ravens demonstrate problem-solving abilities rivaling great apes, including tool use, planning, and deceptive behavior. Found across the Northern Hemisphere from Arctic tundra to deserts, ravens are highly adaptable omnivores. They form complex social hierarchies, engage in cooperative foraging, and have been observed engaging in play. Their intelligence and black plumage have made them figures of mythology across many cultures.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
