Kiwi Bird highlights

A typical kiwi bird egg weighs around 15% of a female’s body weight.

It can, therefore, be up to 20% of her entire weight, which is the equal of a 120-pound (54.4 kg) human woman having given birth to a 24-pound (10 kg) child.

Kiwi is a non-flying bird that is exclusively found in New Zealand and belongs to the Apteryx genus and Apterygidae family.

The kiwi is the tiny extant ratites, about the same size as a domestic chicken. The ancestral wings are so little that they are hidden under the bristly, hair-like bristles of the two-branched feathers. 

Kiwis, like humans and the juvenile of other birds, have marrow inside them, although most older birds have empty insides to conserve weight and make flying feasible.

Because there are no weight constraints imposed by flight needs, brown kiwi females transport and deliver a single egg that can measure up to 450 g. (16 oz).

They lack a uropygial gland, as do most other ratites (preen gland).

New Zealand’s national symbol, the non-flying kiwi, is one of the world’s rarest and most peculiar birds.


The kiwi developed in the absence of most large predators, playing ecological roles comparable to those of several other terrestrial mammals, as indicated by the anatomy of the kiwi.

Marrow is packed within their bones, as it is in the bones of many creatures. To traverse the world, they rely on their senses of touch and smell.

Their silky feathers provide a fur-like feel to them. Despite extensive conservation efforts, this species is on the endangered list.


Regarded as an emblem of New Zealand, as well as the relationship is so powerful that the name Kiwi is used as a common term for New Zealanders across the world.


The surprise finding of Genomic DNA comparisons is that kiwis are considerably more closely linked to the vanished Malagasy elephant birds than to the moa with whom they share New Zealand.

There are 5 types of species that were identified, four of which are endangered and one that is near-threatened.

Historically deforestation has had a significant impact on all species, but its remaining environment is effectively preserved in enormous forest reserves and national parks.

Predation by invading mammalian carnivores is currently the biggest threat to their existence.

Kiwi bird – Characteristics

Kiwis are naturally nocturnal. At night, they are busier, while daytime, they slumber.

They spend the entire night looking for food in the region. When they aren’t looking for food, they protect their area. Kiwis leave particularly odorous droppings to identify their territory.

Only the kiwi’s spouse, young, and adult children are permitted to enter the territory. If the Kiwis venture into each other’s area, they will battle.

In the wild, kiwis live for roughly 20-30 years, but in captivity, they may survive for up to 40 years.

The female Kiwi may give birth to an egg that measures up to a fourth of its weight, which is the strangest aspect of the bird. In terms of proportional size, that was by far the biggest bird egg on the globe.

The egg-to-bodyweight proportion of Kiwis is one of the greatest of any mammal.

A typical egg weighs around 15% of a female’s body weight. It can, therefore, be up to 20% of her entire weight, which is the equal of a 120-pound (54.4 kg) human woman having given birth to a 24-pound (10 kg) child.

A female kiwi will lay one to two eggs at any given moment.

When a Kiwi egg hatches, how long would it take?

Antimicrobial properties in their eggs defend them from germs and fungi present in the moist climates of their native New Zealand. Till the eggs hatch, the males will stay on the pair.


The gestation period for a female kiwi is 75 to 85 days. Unlike other birds, the chick breaks the kiwi’s egg apart and is immediately covered in feathers.

They share the same physical characteristics as their parents. Once the chick hatch, it becomes self-sufficient almost immediately and will not imprint on its parental figures.

The small one will exit the burrows in very few days and spend roughly 20 days with their daddy. Unfortunately, 95 percent of Kiwi girls do not survive to maturity.

Why are the eggs of the Kiwi bird so large?

There might be a variety of intriguing causes behind the kiwi bird’s large egg.

Because of the huge egg, Kiwi chicks have a belly full of yolks, which they may feed off for the first 2½ weeks of their existence. 

Having a newborn kiwi that can better escape death from above might be worth the agony in a setting where there are very few ground-dwelling egg-eating carnivores but numerous chick-eating soaring predators.

Going a step farther, and then you might envision the kiwi outperforming other animals and developing an eggy form of live delivery, with plenty of additional yolks replacing the breastmilk.


The Size, Looks, and Personality of the Kiwi

Brown feathers, a large beak, and a short tail characterize the kiwi bird. It is unable to fly due to its short wings. Worms, insects, and fruit are eaten by the kiwi bird.

Kiwi birds spend their days in the wild, living in trees or bushes and sleeping on branches at night.

With a spherical body, long, narrow bill, muscular feet, drastically shortened wings with claws at the end, tiny whisker-like feathers all around the head, and brown or grey plumage that nearly resembles fur, these are unexpected birds.

The brown kiwi is the biggest species, at 25 inches tall and weighing up to 11 pounds, about equivalent to a domestic chicken.

Males are much larger than females, but apart from that, they appear to be identical.


Conservation and status

Only about 5–10% of kiwi chicks survive to adulthood without supervision, according to national surveys.

Over 70% of the Kiwi population are unsupervised as of 2018.

Life expectancies for North Island brown kiwis can be significantly higher in locations with aggressive pest control.

For illustration, 32 kiwi chicks were radio-tagged before DOC and the Animal Health Board’s combined 1080 poisoning operation in Tongariro Rainforest in 2006.

Only 57% of the radio-tagged girls made it to maturity.
Efforts to safeguard kiwis have had some results, with the IUCN downlisting two species from endangered to vulnerable status in 2017.

The latest Kiwi Protection Plan was issued by the Department of Conservation.
