Range

Widely distributed across Africa (South Africa), Asia (4 countries), Europe (24 countries), North America (Canada, Dominican Republic, United States), Oceania and the Pacific (New Zealand), and South America (Colombia, Peru). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.

Mute Swan

The most commonly encountered swan globally and one of the largest flying birds, mute swans weigh up to 15 kg and inhabit lakes, rivers, and coastal bays across Europe and Asia, with widespread introduced populations in North America and Australia. Despite their name, mute swans produce a range of hissing, grunting, and wing-whistling sounds. Males aggressively defend territories and are capable of injuring humans and drowning dogs with powerful wing strikes.
