Common Ostrich

The world's largest and heaviest living bird, common ostriches stand up to 2.8 meters tall and weigh 156 kg, inhabiting savannas and semi-arid plains of Africa. Flightless, they compensate with powerful long legs capable of delivering lethal kicks and sustaining running speeds of 70 km/h — the fastest of any bird. Their large eyes are the biggest of any land vertebrate. Ostriches lay the largest eggs of any living bird.

Golden Eagle

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.
