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.

Empress Brilliant

A large, brilliantly colored hummingbird of humid Andean forests in Colombia and Ecuador, male empress brilliants are among the most striking hummingbirds with iridescent green and violet plumage and glittering scales across their throat and breast. Found at elevations between 1,000–2,100 meters in cloud forest. Named in honor of Empress Eugenie of France, these powerful birds aggressively defend territory around flowering trees. Listed as Least Concern with stable populations in remaining Andean forest.
