The kori bustard belongs to the Otididae family which consists of a large number of species of birds scattered all over the world in grasslands including the continents of Asia, Europe, Africa, and Australia.
These bustards are medium to large, and there are twenty-nine species under the family of Otididae and order Gruiformes and the kori bustard bird is one of them.
Kori bustards have another name, the great paauw (Ardeotis kori), which was discovered in South Africa, the bustards in this country are called paauw hence the kori bustards have been labeled as the great paauw because they are one of the heaviest birds around.
The term ‘Kori’ was coined by John Burchell who was an English Naturalist in the year 1882 which was obtained from the Tswana language used in parts of Southern Africa.
Kori bustards, of genus Ardeotis, are the heaviest terrestrial bird found in the vast grassy regions of Africa and spend most of their lives standing up. The species of kori bustard is further branched into two subspecies namely, the Ardeotis kori kori and the Ardeotis kori struthiunculus.
Ardeotis kori kori is found in Zimbabwe, Namibia, Botswana, and South Africa. While the Ardeotis kori struthiunculus are found in other parts of Africa including Kenya, Tanzania, and Sudan. This subspecies of kori is also known as the Somali kori.

Kori bustards belong to the class Aves.
How many Kori Bustards are there in the world?
According to the International Union for Conservation of Nature, kori bustards were found in abundance, however, the precise number has not been given, but they have been declared as Vulnerable and Nearly Threatened because of the gradual decline of their population.
Where does a Kori Bustard live?
Kori Bustards are found on the continent of Africa, especially in the southern region. They typically reside in Namibia and Botswana, parts of Ethiopia, Kenya, Tanzania, Zimbabwe, and South Africa, therefore, it can be assumed that this species, and their subspecies, are scattered all over the continent.
Kori bustards are even preserved in various national parks including the Serengeti National Park, the Kitulo National Park, and the Ngorongoro National Park, all situated in Zimbabwe. However, this bird is sparse in the Northern and Eastern Cape regions.
What is a Kori Bustard's habitat?
These are terrestrial, non-migratory birds and the habitat kori bustards prefer can be described as dry grasslands.
Kori bustards may be barely seen or even nonexistent in the eastern part of South Africa, also in the highly elevated mountain areas and the southern coastal regions.
Short grass and scattered trees are favored by these birds because their diet mainly consists of insects which they pick from the ground and trees where the area has sandy soil like the Kalahari sands.
The kori bustard can also survive in areas where the regions are excessively dry, like the arid plateaus and scrublands as well as in the semi-deserts, and the lightly wooded savanna.
This bird utilizes the scanty grass-covered areas as its habitat for breeding and the hilly regions for nesting.
They frequently take shelter under the shade of the scattered trees with water bodies nearby to drink water, rainfall is infrequent in the areas where these birds thrive, and they are also spotted in the agricultural lands where wheat is cultivated.
Who does Kori Bustards live with?
These bustards either live alone or in a small group, the males mostly spend their life alone except for the breeding season.
How long does a Kori Bustard live?
The approximate life span of this bustard is 26 years, but sometimes they may live until the age of 28, however, an accurate estimate for their life expectancy is not known. These birds are vulnerable to various diseases which influence their life span.
How do they reproduce?
This species of bustard is further divided into two subspecies that have two different breeding seasons, the Ardeotis kori kori’s mating season is from September until February, while the Ardeotis kori struthiunculus' mating season is from December to August, and rainfall plays an integral role.
The kori bustard in the wild is polygynous, and a single male bird can copulate with multiple females, the procedure the male follows is called ‘lek mating’ during the breeding season.
Lek mating is the process in which the males form a congregation and take part in the combative display and courtship customs to attract the females.
The males achieve sexual maturity by the time they turn four to six years of age, and females take three or four years to become sexually mature (except in a zoo where they mature more quickly than in the wild).
Males prefer to live alone and only associate with females during the breeding season.
The males generate a call that is low-pitched noise as their mating displays in the presence or absence of females, and gradually the intensity of the call increases with the female birds in sight.
The adult males puff up their throat which appears like a balloon with their head held backward.
The females are drawn to the male after the display and the process of copulation starts, after copulating with the male the females lay eggs after four to six weeks on the ground, and the average litter size is one or sometimes even two eggs.
What is their conservation status?
The kori bustard is a near-threatened species, at one time they were found all over the African continent, but with every passing year their population is declining and in the next three generations the population may face a 10% decrease.
In the protected parts of the land, they are frequently seen but their population has become sparse in other parts.
There are many reasons associated with hunting, getting trapped, poisoning, and most importantly habitat demolition due to cultivation and agriculture.
What is a Kori Bustard's wingspan?
The wingspan of a kori bustard is 84-108 in (213-274.3 cm) for the males and for the females, it is approximately 70in (180cm).
