Ostrich

Ostriches are one of the largest, flightless birds in the world today. Other birds that cannot fly are emus and kiwis. Ostriches are typically found in Africa, roaming in flocks of up to 50 birds. Ostriches can weigh up to 320 lb (145kg). It’s small wings and sheer weight make flying impossible.

Where they cannot fly, ostriches make up for travel by running. Ostriches can sprint up to 43mph (70km/h) and can run at a constant speed of 31 mph (50km/h). When ostriches cannot outrun their predator, they use their powerful legs to kick at the predator. Despite being on the list of top 10 dumbest animals in the world, ostriches do not stick their heads in the ground to render them ‘invisible’ as popular belief has it.
