Ostrich

Born to run

The ostrich is the largest and heaviest living bird. It is a flightless bird that can never take to the skies, so instead it’s built for running. Its long, thick, and powerful legs can cover great distances without much effort, and its feet have only two toes for greater speed.

Ostriches can sprint in short bursts up to 43 miles per hour (70 kilometers per hour), and they can maintain a steady speed of 31 miles per hour (50 kilometers per hour). Just one of an ostrich’s strides can be 10 to 16 feet (3 to 5 meters) long—that’s longer than many rooms! They can also defend themselves: they have a 4-inch (10-centimeter) claw on each foot, and their kick is powerful enough to kill a lion.

What are the wings for?
If they can't fly, why do they have wings? For one thing, ostriches hold their wings out to help them balance when they run, especially if they suddenly change direction. Their main use, though, is for displays and courtship, along with the tail feathers.

Birds of a feather
Unlike many birds, ostrich feathers are loose, soft, and smooth. They don’t hook together the way feathers of other birds do, giving ostriches that "shaggy" look. The feathers can also get soaked in the rain, because ostriches do not have the special gland many birds have to waterproof their feathers while preening.

Do they put their heads in the sand?
Actually, that’s a myth: ostriches do not bury their heads in the sand! When an ostrich senses danger and cannot run away, it flops to the ground and remains still, with its head and neck flat on the ground in front of it. Because the head and neck are lightly colored, they blend in with the color of the soil. From a distance, it just looks like the ostrich has buried its head in the sand, because only the body is visible.

Fun facts

• When family groups of ostriches meet, they may challenge each other with short chases, then the winning adult pair takes all the chicks with them. Some of these "ostrich nurseries" can end up with 300 chicks and only a couple of adults to look after them all!
• One ostrich egg is equivalent to the weight of about 24 chicken eggs!
• Ostriches are attracted to small, shiny objects and peck curiously at them.

Hi Jitti.
I send your ostrich best regards from my goose. Perfect detailed and truly colored portrait of this cute bird. Nice composition and excellent DOF. I like the POV and cropping of your shot. The delicate colour palette is pleasant to eye so much. My best regards and for you.
Alexei.

Hello Jitti,
This is a beautiful portrait of this big bird. You caught excellent details with nice natural lightning and beautiful glance in its eye. I really enjoyed reading our notes as I didn't know many things that I learned reading them. For example, I didn't know that they were so great runners. I heard recently that these birds, along with hippopotamus were the more dangerous animal for human being, capable to kill in a wink... Thanks for this nice and interesting post.

Hello JC,
This is a fine ostrich portrait!
For some reason this one doesn't look as wild as his cousins, this is a more laidback fellow with a better hairdo!
Greetings,
