The largest bird in the world, the ostrich reaches a height between 8 and 9 feet tall and weigh about 300 lbs. Males are slightly larger than females. Sexually dimorphic – males have black plumage with white primary feathers on wing tips and tail while females are an earthy brown. The neck and thigh regions in males are bared skinned and pink. In females, these bare areas are pinkish gray. Newly hatched chicks are fawn with brown spots with a concealing hedgehog-like cape of bristly down on the back.
