How Much Do Ostriches Weigh?

There are two living species of ostrich: the common ostrich (Struthio camelus) and the Somali ostrich (Struthio molybdophanes)

The ostrich is the largest and heaviest living bird

The ostrich is the largest and heaviest living bird

Males are generally larger than females, weighing 220 to 287 pounds and standing 69 to 9 feet tall

Females, meanwhile, weigh 198 to 242 pounds and range in height from 57 to 62 feet

Ostriches are the largest and heaviest birds in the world

Instead, ostriches are great runners and can reach speeds of up to 43 miles per hour

A step can be 10 to 16 feet long

They have long, strong legs with two clawed toes, enabling them to achieve this high speed

The ostrich has a long neck, prominent eyes and wide eyelashes

The ostrich has the largest eyes of any land animal

Their long necks and excellent vision help them see long distances, allowing them to keep an eye on predators

The ostrich has a unique plumage that is loose, soft and smooth, giving them a “shaggy” appearance

Adult male ostriches are black with white wings and tail feathers, while immature birds and adult females have brownish gray feathers

Their diet varies depending on the food available in their habitat

Ostriches also swallow sand, gravel, and small stones that help break up food in their gizzards

Because they eat a lot of plants, ostriches do not need to drink water

Ostrich habitats include savannas and desert regions

A male used the black and white color to attract the female

It sinks to the ground like a bow, then waves and shakes the feathers of first one and then the other wing while moving its tail up and down

After this movement, he stands up and walks towards the female, spreading his wings and strutting to impress her

The dominant female will mate with the territorial male and they will share incubating the eggs and caring for the chicks

The territorial male is polygamous and may mate with other females

The other females can also mate with migrating males

The other females then lay their eggs in the same nest as the dominant hen’s eggs

The nest is a shallow depression scratched in the dirt by the male

The dominant hen ensures that her eggs are closest to the center and are therefore most likely to hatch successfully

A shared nest allows more eggs to hatch successfully for the flock

A female ostrich lays 7-10 eggs at a time

Ostrich eggs are the largest eggs, weighing about 3 pounds, 6 inches long and 5 inches in diameter

Only dinosaurs produced larger eggs

Chicks are about the size of chickens when they hatch, but they grow 1 foot per month

The chicks leave the nest with their parents a few days after hatching

At four months, their adult plumage begins to appear, and by six months they are about the same size as their parents

Ostriches reach sexual maturity around the age of three or four, when the black and white feathers of the males grow out

Ostriches live in groups, which helps them defend themselves

They usually occur in flocks of about 10 birds or just one male and female pair, but sometimes gather in large flocks of 100 or more

These groups have a dominant male, a dominant female called the “head hen” and several other females

The dominant male establishes and defends his territory

During the breeding season, solitary males may also come and go

In the wild, ostriches live 30-40 years

But in captivity, ostriches live up to 70 years

Ostriches have many natural predators, including cheetahs, lions, leopards, hunting dogs and spotted hyenas

Other predators, such as Egyptian vultures and jackals, may take ostrich eggs

When an ostrich senses danger and is unable to run away from the threat, it falls to the ground and remains motionless with its head and neck on the ground, blending into the ground

When threatened, an adult ostrich attacks with a clawed foot that delivers a kick strong enough to kill a lion

Humans also pose other serious threats to ostrich populations and their habitats

As human populations grow and expand, ostriches are losing their habitat

Ostrich feathers have long been popular in fashion

In the 18th century, ostrich feathers were so popular in fashion, especially in the hat industry, that the ostrich population declined

Ostrich farming helped the population recover and still continues on a smaller scale

Ostriches are bred and hunted for their feathers, hides, meat, eggs and fat

Strict protection and management are needed to preserve the remaining ostrich populations

Conservation groups and government agencies are working to protect these populations

For example, the San Diego Zoo Safari Park works with the Niger red-necked ostrich, providing technical expertise and funding to develop and manage the birds’ breeding program

This will help to develop a safe and self-sustaining population in the country

The African Wildlife Foundation is helping to conserve ostrich populations by working with local communities to decide on a suitable plan to start tourism in the area

Ostriches are the largest, tallest and heaviest birds in the world

Although the ostrich is a bird, it is completely flightless

How much does the ostrich weigh?

A male ostrich weighs 250 to 350 pounds (113 to 158 kg)

Female ostriches weigh about 220 to 300 pounds (100 to 136 kg)

How much does the baby ostrich weigh?

They are small at birth, weighing only 2-3 pounds (090-136 kg)

However, they don’t stay small for long

By the time they reach 6 months of age, they will weigh close to 150 pounds!

The ostrich can run extremely fast, reaching speeds of up to 40 miles per hour, while sometimes taking strides of up to 16 meters

An ostrich kick can be very powerful and has enough power to kill a human or even a lion

The average ostrich can grow up to 9 feet tall and live for 40-50 years

The ostrich has only 2 toes on its feet

All other birds will have at least 3 or 4

They can eat plants, vegetables and sometimes meat, including mammals and reptiles

~Fun Fact~A typical ostrich egg takes about 2 hours to hard boil
