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.
