The common ostrich (Struthio camelus) is the tallest living bird, males standing 2.1–2.75 m and weighing 100–130 kg, females 1.75–1.9 m and 90–120 kg. The sternum lacks a keel, the wings are flightless and the foot bears only two toes. Males are black with white flight and tail feathers; females are greyish-brown. It inhabits savanna, semi-desert and Sahel across sub-Saharan Africa. Plant matter, insects and small vertebrates are eaten, grit up to 1.3 kg aiding digestion, and running reaches 70 km/h. The IUCN lists it Least Concern.
