An ostrich changes the feeling of open country.
It stands high above the grass, long neck lifted, eyes wide, body balanced on two powerful legs. From far away, it may look almost fragile: a dark shape moving through heat shimmer, feathers loose in the wind. Then it runs, and the illusion disappears. The ostrich is not awkward. It is built for speed, distance, and survival in exposed landscapes.
Unlike many birds, the ostrich does not escape by flying. It survives by seeing danger early, moving fast, nesting on the ground, and using legs strong enough to outrun many threats and defend itself when cornered. It is the largest living bird on Earth, a grazer, an omnivore, a desert-edge wanderer, and one of Africa’s most distinctive open-country animals.
To understand the ostrich is to understand a bird that gave up flight but kept the sky in its posture.

What Is an Ostrich?
An ostrich is a large flightless bird native to Africa. The most widespread species is the common ostrich, Struthio camelus. A second living species, the Somali ostrich, Struthio molybdophanes, is recognized by BirdLife International and the IUCN as distinct.
Ostriches belong to a group of flightless birds called ratites, which also includes emus, cassowaries, rheas, and kiwis. Unlike flying birds, ostriches have a flat breastbone without the strong keel that anchors large flight muscles. Their wings are still useful, but not for flight. They help with balance, display, shade, and communication.
The ostrich is the largest living bird. It is also the fastest bird on land. Its survival strategy is based on long sightlines, strong legs, endurance, group awareness, and a powerful kick when escape is not possible.
Top Questions
No. Ostriches are flightless birds. Their bodies are too large and their wings are not built for powered flight.
Ostriches can run at high speeds, often cited around 70 km/h in short bursts, and they can maintain fast running over distance.
They can be dangerous if cornered, threatened, or defending chicks. Their powerful legs and claws can deliver serious kicks.
No. This is a myth. Ostriches may lower their heads to inspect nests, feed, or lie flat when hiding, but they do not bury their heads to avoid danger.
Ostriches are omnivores. They mainly eat plant material such as grasses, leaves, seeds, roots, and fruits, but they also eat insects, lizards, and other small animals.
The common ostrich is listed as Least Concern, though its population is decreasing. The Somali ostrich is listed as Vulnerable.
General Characteristics
Ostriches are unmistakable. They have long bare legs, two toes on each foot, a long neck, small head, large eyes, soft loose feathers, and a large rounded body.
Their legs are among their most important adaptations. Unlike most birds, ostriches have only two toes on each foot. The larger inner toe carries a strong claw and helps with speed and traction. Their long legs allow them to cover ground efficiently and run quickly from predators.
The eyes are large, giving ostriches excellent long-distance vision. In open country, this matters. An ostrich can often detect danger before many other animals do. Zebras, antelope, and other grazers may benefit from feeding near ostriches because of their alertness.
Male and female common ostriches differ in appearance. Adult males are usually black with white wing and tail feathers, while females are generally grey-brown. This difference is useful during nesting: darker males are less visible at night, while browner females blend better during daylight.
Ostrich feathers are soft because they lack the tight interlocking structure of many flying birds’ feathers. Wings are used in courtship displays, balance while running, shading chicks, and signaling.
Habitat and Distribution
Common ostriches live in open and semi-open habitats across parts of Africa. They are associated with savannas, dry grasslands, shrublands, semi-deserts, Sahelian zones, open plains, and arid regions.
They generally avoid dense forest because their survival depends on visibility and running space. In southwest Africa, ostriches can live in very dry landscapes, including desert-edge regions, where they feed on sparse vegetation and travel widely.
Important viewing areas include Namibia, Botswana, South Africa, Kenya, Tanzania, Ethiopia, parts of the Sahel, and other open African landscapes where wild or managed populations occur.
The Somali ostrich is found in the Horn of Africa region, especially Somalia, Ethiopia, Djibouti, and Kenya. It is adapted to arid and semi-arid habitats and is under greater conservation pressure than the common ostrich.
Historically, ostriches occupied a wider range, including parts of the Middle East. The Arabian ostrich, once found in the Near and Middle East, became extinct in the 20th century.
Behavior and Social Life
Ostrich social life varies with season, habitat, food, and breeding.
They may be seen alone, in pairs, in family groups, or in loose groups. In some open areas, especially where food is patchy or conditions are dry, groups can become larger. Ostriches may also move near zebras, antelopes, and other grazers.
During breeding, males become territorial and perform dramatic displays. A displaying male may lower himself, spread and wave his wings, sway the neck, and show contrasting black and white feathers. He may also produce deep booming calls.
Ostriches are alert birds. They rely on eyesight, hearing, speed, and group awareness. When danger is far away, they often walk or run off. If pressed, they can sprint powerfully. If cornered, they may kick forward with great force.
They communicate through posture, wing movement, hisses, booming calls, and visual displays. Much of their behavior is shaped by open-country visibility: standing tall, watching, moving early, and avoiding close-range danger.
Diet and Feeding
Ostriches are omnivores, though their diet is mostly plant-based. They feed on grasses, leaves, roots, seeds, flowers, fruits, succulents, and shrubs. They also eat insects, lizards, small reptiles, and other small animals when available.
Because they have no teeth, ostriches swallow small stones and grit that help grind food in the gizzard. This allows them to process tough plant material.
Ostriches can survive in dry areas by using moisture from plants and by moving to find food. Their diet shifts with season and availability. After rain, they may feed on fresh green growth. In dry periods, they may use tougher vegetation, seeds, roots, and succulents.
Their feeding can influence seed dispersal and nutrient cycling in open habitats. They are also part of mixed grazing communities, often moving in landscapes shared with zebras, wildebeest, gazelles, or antelope.
Reproduction and Life Cycle
Ostrich breeding behavior is one of the most interesting parts of their natural history.
A territorial male may mate with several females, but often forms a stronger bond with a main female. Females lay eggs in a communal ground nest, usually a shallow scrape made by the male.
A shared nest can contain many eggs, but not all receive equal care. The major female often places her eggs in the center, where they are safest. Extra eggs from other females may sit nearer the edge and be more vulnerable.
Ostrich eggs are the largest eggs of any living bird. Each egg is thick-shelled and heavy, though relative to adult body size it is not as large as some smaller birds’ eggs.
Incubation lasts about 42 days. In common ostriches, the female often incubates during the day, when her brownish coloration blends with the ground, while the darker male may incubate at night.
Chicks are mobile soon after hatching and follow the adults. They are vulnerable to jackals, hyenas, lions, leopards, cheetahs, raptors, mongooses, and other predators. Adults may defend chicks with distraction, display, running, and kicks.
Young ostriches grow quickly but remain at risk for months. Survival depends on food, cover, predator pressure, weather, and adult protection.
Predators and Defense
Ostriches face predators throughout their lives. Eggs and chicks are taken by jackals, mongooses, raptors, hyenas, warthogs, and other opportunists. Adults may be hunted by lions, leopards, cheetahs, spotted hyenas, and African wild dogs, though a healthy adult ostrich is not easy prey.
Their first defense is early detection. A tall head and large eyes allow them to spot danger across open ground. Their second defense is speed. Ostriches can cover distance quickly and may outrun many predators in open terrain.
If cornered, an ostrich can kick with great force. The kick is forward and downward, powered by strong legs and sharp claws. This defense is serious enough that large predators must be careful.
The myth that ostriches bury their heads likely comes from their behavior around nests and their habit of lowering the head and neck when trying to stay inconspicuous.
Taxonomy
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Struthioniformes
Family: Struthionidae
Genus: Struthio
| Species | Scientific Name | Conservation Status |
|---|---|---|
| Common ostrich | Struthio camelus | Least Concern |
| Somali ostrich | Struthio molybdophanes | Vulnerable |
Common ostrich subspecies commonly discussed include the North African ostrich, South African ostrich, and Masai ostrich. The Arabian ostrich is extinct.
Taxonomy has shifted over time. The Somali ostrich was previously treated as a subspecies by some authorities but is now recognized as a distinct species by BirdLife International and the IUCN.
Conservation Status
The common ostrich is listed as Least Concern, but its population trend is decreasing. BirdLife International estimates a population of roughly 300,000 to 900,000 individuals, while noting suspected continuing decline.
The Somali ostrich is listed as Vulnerable and is thought to be declining rapidly because of hunting, egg collection, habitat pressure, and persecution.
Major threats include:
- Hunting for meat, feathers, skin, and eggs.
- Egg collection.
- Habitat loss and degradation.
- Overgrazing by livestock in some areas.
- Fencing and movement barriers.
- Disturbance at nesting sites.
- Hybridization concerns in some managed or farmed contexts.
- Local persecution.
- Drought and climate pressure in arid landscapes.
Ostrich farming is widespread in some countries, especially for meat, leather, feathers, and eggs. Farming can reduce pressure on wild populations in some contexts, but it can also create management questions around escapes, hybridization, disease, and conservation genetics.
Conservation priorities include protecting open habitats, reducing illegal hunting and egg collection, monitoring wild populations, conserving North African and Somali ostrich populations, and preventing careless mixing of distinct ostrich forms.
Human Relationship and Responsible Travel
Ostriches are often easy to see in open landscapes, but they still need respectful viewing. A bird that looks relaxed may be watching the vehicle carefully, especially during breeding season or when chicks are nearby.
Travelers should not chase ostriches to make them run. A running ostrich is impressive, but forcing flight wastes energy and may separate chicks or disturb breeding birds.
Never approach nests, eggs, or chicks. Ground nests are vulnerable, and adult ostriches may defend them. Guides should keep distance and avoid drawing attention to nesting sites.
Good viewing means watching natural behavior: feeding, dust bathing, display, calling, escorting chicks, moving with antelope, or scanning the horizon. The most memorable ostrich moments often come from patience, not pursuit.
A respectful ostrich sighting lets the bird remain alert, unhurried, and in control of its space.
Final Reflection
The ostrich is a bird of open horizons. It cannot fly, but it does not need to. Its world is distance, speed, heat, dust, grass, and the long view.
Its height makes it visible; its life makes it interesting. It is a runner, a watcher, a nest defender, a mixed-feeding survivor, and a reminder that birds can belong fully to the ground without losing their wildness.
To watch an ostrich well is to see the open country through its eyes: danger far off, movement always possible, and survival written into every stride.
