Kori Bustard Display | Heaviest Flying Bird | Kruger National Park

A male Kori Bustard showing his breeding display. Kori bustards engage in lek mating. All bustards have polygynous breeding habits, in which one male displays to attract several females, and mates with them all. Males display at regularly used sites, each male utilizing several dispersed leks or display areas. These displays usually take place in the mornings and evenings. The courtship displays of the males are impressive and elaborate, successfully advertising their presence to potential mates. The males hold their heads backwards, with cheeks bulging, the crest is held erect, the bill open and they inflate their gular pouches, forming a white throat "balloon". During this display the oesophagus inflates to as much as four times its normal size and resembles a balloon. They also puff out their frontal neck feathers which are splayed upwards showing their white underside. The white may be visible up to 1 km (0.62 mi) away during display. Their wings are drooped and their tails are raised upwards and forwards onto their backs like a turkey, the rectrices being held vertically and their undertail coverts fluffed out. They enhance their performance with an exaggerated bouncing gait. When displaying they stride about with their necks puffed out, their tail fanned and their wings planed and pointed downward. They also emit a low-pitched booming noise when the neck is at maximum inflation and snap their bills open and shut..
The kori bustard (Ardeotis kori) is arguably the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species (ranging from Africa to India to Australia) in the large-bodied genus Ardeotis. In fact, the male kori bustard may be the heaviest living animal capable of flight.

This species, like most bustards, is a ground-dwelling bird and an opportunistic omnivore. Male kori bustards, which can be more than twice as heavy as the female, attempt to breed with as many females as possible and then take no part in the raising of the young. The nest is a shallow hollow in the earth, often disguised by nearby obstructive objects such as trees.

About Rob The Ranger Wildlife Videos:
The purpose of the channel is to show what it is like to experience seeing wild animals on an African safari. Nature Documentaries are often highly edited to tell a story, wildlife safaris are not, and the idea here is to show the wildlife sightings the way they were seen. Safari tours in Africa are generally suitable for all ages and this channel can be considered an educational channel about incredible nature, some scenes in the nature videos may be more graphic than people are used to but this is the reality of nature and is what you would see if you were present on such a safari in person. Safaris in Kenya, South Africa, or any other African country are an unrivalled experience for anyone with a passion for nature, wildlife photography, and travel. Hopefully the animal videos on this channel can provide a glimpse into what the nature experience is like and encourage more people to take a wildlife safari one day.
