Ardilla Gris Oriental

Native to eastern North America but successfully introduced to Europe and other regions, the eastern gray squirrel is a medium-sized arboreal rodent weighing up to 600 g. Highly adaptable, thriving in forests, parks, and urban gardens, gray squirrels cache thousands of nuts and seeds each autumn, inadvertently planting trees through forgotten caches. In Britain, they have largely displaced the native red squirrel by outcompeting them for food.

brown bear

The world's most widely distributed bear species, brown bears range from North America and Europe across Russia to Japan, occupying forests, tundra, and alpine meadows. Adults can weigh up to 700 kg in coastal Alaskan populations. Omnivores that consume berries, roots, fish, and carrion, brown bears are a keystone species that distribute nutrients across landscapes. Most populations are stable, though some subspecies are threatened.
