Hunting Behaviors Hunt by sight May watch a herd from vantage point Termite mounds, trees, or other high points used to scan for prey Silently stalk prey Use cover to obscure movements Creep as close as possible, in a semi-crouched position Head lowered Trot, freeze, and drop to the ground to avoid discovery Stalk to within 50 m ft before charging Prey selection Choose isolated individuals or fawns, flushed out from hiding places Hunting behavior intensified when prey runs Animals that do not run are sometimes left alone Chase and take down strategies Success rate c.
Can be heard from a distance of 2 km "Whirring" Equivalent to a warning growl Heard by juveniles at a kill as they compete for food Can turn into high-pitched rasp or squeal "Chirping" Greeting between cheetahs who know each other, around female in estrus, or at scenting post Can be accompanied by purring "Purring" During play and friendly meetings May be accompanied by cheek rubbing, mutual sniffing and face licking "Stutter bark" Caro calls this "churring" Rapid, repetitive, low pitched sound Usually made by males when estrus female detected, occasionally by female when approached by males "Yowling" Drawn-out bleat-like moan Olfactory signals Scent marking in cheetahs predominantly male activity Females mark around the time of estrus Marking techniques Territories and preferred routes are marked with urine, feces and occasionally claw marks.
Males use urine to mark prominent structures mounds, boulders, trees Feces may also be deposited on prominent landmarks. Zoology 3 : 64 mph kph. Antelopes: speed reaches kph mph They can run much further than cheetahs Hunting sprints last for m Captive cheetah race in Cape Town, South Africa, won by 3 year old male meters in 6.
While the females were on a walk, the staff moved the largest nest box xx0. They were again carried back by the keepers and the females were let back in from the outside enclosure. Once the mothers lied down with the cubs, they calmed down. The females took turns feeding the young; they crawled from one mother to the other and slept in a general group.
An attempt to divide the females caused anxiety in them and it was not attempted again. On May 12, , a clear difference regarding the relationship of the females to the young emerged: Mary spent more time on walks or would lie nearby while Nanga fed all the cubs or groomed them. She would go on walks, making sure the cubs were sleeping and there were no outsiders in their dwelling.
Sometimes both females lied on one nest box opposite one another and fed at the same time, but more cubs were always observed around Nanga. Starting on June 1, , the cubs ate meat on the bone and walked with the females in open enclosures.

What environmental conditions support group living in cheetah females? In captivity animals regularly receive food; they are provided with shelter and are protected from natural enemies.
Captive cheetah females demonstrate higher levels of sociality than in the wild where enemies lions, hyenas and leopards still their prey, kill cubs and even adult cheetahs. Predator conflict is a primary limiting factor to cheetah life expectancy — in the wild they rare reach the age of 11, while in captivity can live for up to years. In literature, there is information on groups of females gathering in different parts of Africa.
Moreover, observations in Botswana Vandermey, suggest the possibility for reproduction in females living together.
In one territory, four females were observed: one with cubs approximately 6 month old and a group of three year old females. Female cheetah home ranges depend on the distribution of prey. If prey is roaming and widespread, females will have larger ranges. Estrus in female cheetahs is not predictable or regular. This is one of the reasons why it is difficult to breed cheetahs in captivity.
Mating receptivity depends on environmental factors that, researchers have found, are triggered by the proximity of males and their scent markings. Estrus lasts up to 14 days and females will mate with multiple males during this time period.
Male cheetahs that encounter a female cheetah in estrus will stay with her and mate up to three days and at intervals throughout the day. When it comes to mating, there are no dominant males within the coalition that claim exclusive access to females. All males within a coalition will mate. Unsustainable human expansion and irresponsible consumption can cause pressure on ecosystems worldwide.
Population research has shown that when habitat is destroyed and populations become fragmented and isolated, the rate of inbreeding increases and the genetic diversity lowers. Physiological impairments such as: poor sperm quality, focal palatine erosion, susceptibility to infectious diseases, and kinked tails are a result of low genetic diversity within both the wild and captive cheetah population. Cheetahs are visual hunters. Unlike other big cats cheetahs are diurnal, meaning they hunt in early morning and late afternoon.
The hunt has several components. It includes prey detection, stalking, the chase, tripping or prey capture , and killing by means of a suffocation bite to the throat. The prey species on which the cheetah depends have evolved speed and avoidance techniques that can keep them just out of reach. Cheetahs will also prey on the calves of larger herd animals.
Cheetahs generally prefer to prey upon wild species and avoid hunting domestic livestock. The exception happening in sick, injured and either old or young and inexperienced cheetahs. Keeping livestock in kraals and utilizing non-lethal means of protection can dramatically reduce livestock predation.
While cheetahs can reach remarkable speeds, they cannot sustain a high speed chase for very long. They must catch their prey in 30 seconds or less as they cannot maintain maximum speeds for much longer. Cheetahs spend most of their time sleeping and they are minimally active during the hottest portions of the day. They prefer shady spots and will sleep under the protection of large shady trees.
Cheetahs do not hunt at night, they are most active during the morning and evening hours. The cheetah serves a special role in its ecosystem. Cheetahs are one of the most successful hunters on the savanna but their kills are very often stolen by larger carnivores or predators that hunt in groups. Predators play an important role in any ecosystem.
They keep prey species healthy by killing the weak and old individuals. They also act as a population check which helps plants-life by preventing overgrazing. Without predators like the cheetah, the savanna ecosystem in Namibia would be very different and the current ecological trend toward desertification would be accelerated. They growl when facing danger, and they vocalize with sounds more equivalent to a high-pitched chirp or bubble and they bark when communicating with each other.
The cheetah can also purr while both inhaling and exhaling. Only a handful of individuals remained. The population of cheetahs rebounded. Once found throughout Asia and Africa, today there are fewer than 7, adult and adolescent cheetahs in the wild. In Namibia, they are a protected species. Most wild cheetahs exist in fragmented populations in pockets of Africa, occupying a mere 9 percent of their historic range. In Iran, fewer than 50 Asiatic cheetahs a sub-species remain. The largest single population of cheetahs occupies a six-country polygon that spans Namibia, Botswana, South Africa, Angola, Mozambique and Zambia.
In captivity cheetahs can live from 17 — 20 years. In countries across Africa, like Namibia, it is illegal to capture and take live cheetahs from the wild.
Also in the majority of African countries, like Namibia, it is illegal to keep cheetahs under private ownership or as pets. Cheetah Conservation Fund and other Africa-based NGOs keep populations of injured or orphaned animals in captivity as part of rehabilitation and rewilding efforts.
Very young and extremely ill animals will have greater degrees of contact with human caretakers. Survival in the wild depends on an aversion to humans and avoidance of human populations.
Cheetahs that require hand-rearing and prolonged medical treatment do not possess an adequate fear of humans for life in the wild, especially when their territories are increasingly likely to be shared by human settlements.
Accredited zoos around the world participate in captive breeding programs that track the genetic suitability for mating pairs.
