The Somali ostrich is a distinct species of an ostrich that closely resembles the extinct Arabian ostrich. Due to its large size, the ostrich is flightless; however, it makes up for it with amazing speed. The ostrich is one of the fastest land animals on earth and can reach speeds of up to 70km per hour. The ostrich is best known for its extremely long neck and legs, which extend from a large round body. The legs are positioned perfectly to provide a centre of gravity, giving the ostrich its speed and mobility. Male ostriches have stark black and white plumage, which they use to attract females, whilst the female ostrich is slightly larger with dull grey-brown plumage. Unlike other species of ostriches, the Somali ostrich has a grey-blue neck, which turns bright blue during the mating season.
