The ostrich is the world’s fastest bipedal animal, in addition to being the tallest and heaviest of all birds. Not only are ostriches recognizable for their towering, almost prehistoric appearance, but they are also exceptional runners, capable of completing a marathon in under an hour and a half. What do ostriches eat? Their massive frames would seem to warrant correspondingly massive appetites.
Ostriches are omnivores, meaning that they eat both plant and animal matter. This includes a wide variety of foods, including insects, lizards, small rodents, and fruits. Ostrich adults require just 1.8 kilograms of food per day, so they’ll make do with almost anything. There is a tendency for them to be vegetarian.

Even though they are technically omnivores, ostriches get more than half of their nutrition from plants. Twenty percent of an ostrich’s diet is composed of the stones, sand, and grit that it uses in its specialized muscular stomach, the gizzard. They are able to digest almost anything they eat this way.
There is no larger living bird than the ostrich. The largest known egg is laid by the female, who may reach 9 feet in height, and the largest known male can weigh over 300 pounds. The ostrich’s appearance hints at its dinosaur ancestry and is a strange blend of gorgeous and hideous. The long, scaly legs, the big eyes, the sparse covering down around the neck. It has two hideous toes, and one of them seems to be shaped like a hoof. Since they lack the barbs seen on normal feathers, however, these feathers are fluffy and soft. The ostrich almost went the way of other massive flightless birds like the big moa because of the demand for the white plumes on the male’s wings and tail. The bird is still kept as a pet due to the demand for its feathers, as well as its eggs, flesh (which tastes similar to venison), and hide (which can be tanned into leather).
The arid environments are ideal for ostriches. In these circumstances, food supplies are low. Ostriches are able to switch easily between plant and animal sources of nutrition because of their omnivorous nature. They will devour almost anything if given the chance. Leaves and plants provide the majority of their diet in the wild, where they can be browsed.
Sixty percent of a wild ostrich’s diet is predicted to come from plants. They eat everything from plant leaves to roots and seeds. Scavenging on the carcasses of other animals is another source of nutrition for ostriches. Rodents, snakes, lizards, and other reptiles, as well as insects like grasshoppers, locusts, crickets, and moths, make up their diet. Fruits and legumes make up about 15% of an ostrich’s diet; 20% is made up of salts, grains, and stones; and 5% is made up of animals and insects.
What do ostrich chicks eat?
Some birds, contrary to popular belief, can actually generate a milk-like substance called crop milk to feed their young. Despite this, ostriches do not provide breast milk for their offspring. When ostrich eggs hatch, the chicks take up the remaining yolk sac contents through their belly. For the first two weeks of life, the nutrients in the sac are essential. In order to ensure appropriate growth when the sac is being depleted, they should start eating around day 7.
Chicks start to rely on browse as their primary food source after two weeks of age. Babies raised in captivity or in a farm environment will be fed ground food or pellets that should be supplemented with little pebbles the size of rice grains. Ostrich chicks learn to feed themselves in the wild by watching and mimicking their parents. When raising ostriches in captivity or on a farm, it is crucial to ensure the young birds have access to an adult ostrich so they may learn proper feeding techniques.
What Do Adult Ostriches Eat?
Ostriches, in all candor, will eat just about anything. According to the classification system, these flightless birds consume both plant and animal products, making them omnivores. The grass, flowers, leaves, shrubs, bushes, plant roots, seeds, fruits, vegetables, stones, and repeating are all fair game for the largest bird in the world. As omnivores, ostriches also feed on rodents, snakes, lizards, frogs, grasshoppers, locusts, cd moths, and other small insects, reptiles, and arthropods. Give ostriches the freedom to eat whatever they want, and you can bet that you’ll find them gorging on things like plant roots, seeds, locusts, lizards, and snakes.
In what ways do ostriches poop up their food?
Three stomachs are normal for ostriches. This will sidestep a couple of issues: Ostriches have no denticulation, and the plant matter they eat has a high cellulose concentration, making it difficult to digest. Birds have no teeth, thus they have to swallow their food whole. This necessitates a unique process for breaking down their food before it enters the digestive tract, where it may be absorbed.
What’s their answer? A strong muscular stomach called a gizzard does the work of grinding food for them. An additional feature is a proventriculus, which functions as a “real stomach” for these creatures. The first stomach secretes chemicals that further decompose the food that has already been chewed and crushed into smaller macromolecular components. In order to better grind and digest their food, ostriches will continually pass it between their gizzard and proventriculus. After the meal has gone through the necessary number of cycles, it enters the gut to be absorbed. An ostrich’s digestive process is so lengthy that it takes about 36 hours.
Although it is technically an omnivore, the ostrich prefers to eat plant matter. This includes:
- Shrub and bush foliage
Of course, the ostrich is an omnivore, therefore it has also been observed eating these things:
- Crickets and locusts and other insects
- Tiny tortoises
- Mice and rats and other little critters
They also scavenge off the carcasses of animals that larger predators like lions have killed.
One of the oldest bird species, ostriches have deep roots in ancient culture. Though it is possible to ride an ostrich by following all the rules and regulations, however, these birds are not made purely for rides.
If you care about the welfare of the ostriches you encounter, you should probably avoid the temptation to ride one. If the rider is still inclined to do so, only go for ostrich riding on certified farms after taking a few lessons.
