What to Ostriches Eat

What to Ostriches Eatの基本情報から最新動向までをわかりやすく整理しました。

First, let’s get the boring stuff out of the way: plants. Ostriches are massive vegetarians by default. Their natural diet is about 80% plant matter, and they are not picky about it. They munch on grass, leaves, seeds, roots, and flowers like a giant, flightless vegan influencer at a farmer’s market.

They have a particular taste for succulents. In the wilds of Africa, they’ll demolish a patch of tough, spiky plants that would make a goat weep. Their gizzard—a muscular stomach pouch filled with stones—grinds this fibrous junk into digestible mush. Basically, they have a built-in blender made of rocks. Metal.

But here’s the kicker: they don’t just eat the good bits. They’ll eat everything that looks even remotely edible, including twigs, bark, and the occasional unlucky insect. It’s less “fine dining” and more “hobo foraging.”

The Sanitary Superpower

Now, here is where it gets wonderfully weird. Ostriches are famous for eating gravel. Yes, gravel. Rocks. Pebbles. If you dump a bag of driveway stones in front of an ostrich, it will look at you like you just offered it a Michelin-star meal. They swallow these stones deliberately and store them in their gizzard.

Why? Because they don’t have teeth. And since they can’t chew their food, they use these pebbles as internal grinding stones. The rocks tumble around in their stomach, pulverizing tough seeds and stalks into a smooth paste. It’s like having a food processor made of geology in your belly. “Excuse me, waiter, there’s a small boulder in my salad.” “Yes, that’s the course.”

And they don’t stop at rocks. If an ostrich finds a shiny coin, a piece of glass, or a lost car key, it will absolutely try to swallow it. This is not a joke. Zookeepers have to be incredibly careful, because an ostrich will eat anything that fits in its beak, including metal bolts, plastic toys, and your watch. They are the goat of the dinosaur world, but with better eyelashes.
