COMMON OSTRICH

Struthio camelus

The biggest of all birds on Earth in both size and weight is undoubtedly the ostrich. These behemoth birds grow up to 2.7 metres tall and can weigh up to 130 kilograms. Despite having a wingspan of up to two metres, ostriches are unable to fly. Instead they use their wings in a similar way to how a ship uses its sails. During a fierce 43 mile per hour run, these birds open out their wings and use them as air rudders for rapid braking and steering. This agility allows them to escape some of the many threats they face on the African savanna, including predatory species such as lions and jackals. In some situations, ostriches will go on the offensive, using their powerful clawed feet to deliver a blow strong enough to kill a lion.
