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.

Ruddy-breasted Seedeater

A tiny, chestnut-red seedeater of open grasslands, weedy fields, and marshes distributed across Central America and most of South America east of the Andes to Argentina, ruddy-breasted seedeaters have warm rufous-red plumage in males with darker wings. Among the most widely distributed Sporophila seedeaters, they thrive in disturbed agricultural landscapes and secondary growth. They forage in small to large flocks on grass seeds and cereal crops. Least Concern with populations benefiting from agricultural expansion.
