The Ostrich (Struthio camelus), also known as the common ostrich, is a species of ratite native to Saharan and Sub-Saharan Africa. They are the largest birds in the world, with large males weighing up to 300 lbs. They can grow up to 9 ft tall, making it the 3rd tallest land animal after the giraffe and the African bush elephant. The males and females are quite easy to tell apart. The males have black feathers with white tipped tail and wing feathers, while the female has gray or brown feathers.
