CHEETAH and SARCOPTIC MANGE – POSITIVE NEWS

03/14/2021

Sarcoptic mange is a highly contagious mite infection caused by Sarcoptes scabiei burrowing under the skin of domestic and wild mammals. It has been reported from 10 orders, 27 families and 104 species of domestic, free-ranging and wild mammals, including cheetahs. Cheetahs acquire it via direct contact with infected prey species or conspecifics. Clinical symptoms of mange depend on the immune status of the respective host. At the latest stages, the skin becomes extensively thickened, greyish in color, there is a marked eosinophilia throughout the epidermis and dermis (the skin becomes red in color) and often almost complete alopecia. The skin cracks, dries and exfoliates exposing the unprotected tissues. Treatment of infected individuals in the field has been successful. In addition, some cheetahs recover by themselves. One of the best examples is a female Maridadi, who we first met as adolescent at the border with Tanzania in 2016 soon after she had separated from her family. In 2018, we found Maridadi in a poor condition with mange (4-5 stage), and informed the KWS Vet team. However, she disappeared for a long time, leaving us in doubt about her physical condition, to appear this year in great shape and accompanied by a big cub! So far, she has had two confirmed litters, and now there is hope that she will be able to raise her cub.
In general, in the population of Mary cheetahs, there is a pronounced trend towards a decrease in the incidence of scabies. In 2012, 22 (10.10.2) cheetahs (29%) were spotted with different stages of mange, of which 8 (3.3.2) were treated by the Veterinary Units, and 3 (1.2) recovered by themselves. In 2014-2015, 10(3.6) were spotted with mange (13%), in 2016, 5(3.2) with mange (8.5%), in 2017, 4(2.2) – 5,4%, in 2018, 2(0.2) – 3%; and in 2019 – 5(3.2) or 7% adult cheetahs, out of which 2 males spent most time in Serengeti. In 2019, two young cheetahs (1.1) have been treated by the KWS Vet Unit and one female recovered by herself. In 2020, 0% cheetahs were spotted with mange.

                 



NASHULA – NEW CHEETAH FEMALE IN THE MARA

03/04/2021

The absence of a physical boundary between Mara and Serengeti allows cheetahs, like other species move freely throughout the ecosystem. Some Mara-born cheetahs migrate to Tanzania, and some Tanzanian-born ones come to the Mara. Approximately every 3-4 months we meet new cheetahs. The appearance of new females with offspring is very special. In early January, a female with three half-year-old cubs appeared in the Sopa area of the Reserve. She was recently named Nashula (means “Mix” in Maa) for spending time in both Tanzania and Kenya. It is noteworthy that each time in the Mara, she explores new territories: in mid-February, Nashula was seen leaving for the Serengeti at the Sand river area, and by early March, she had already mastered the Siana conservancy. In January, the cubs were extremely shy, but now they are used to the presence of vehicles, giving us the opportunity to observe them. Such long-distance journeys are crucial for the future resettlement of the offspring. When the mother leaves the cubs and they start living on their own, it will be easier for them to establish their territories/home ranges, since they will be familiar with large areas.

               



UPDATES on NEEMA

02/22/2021

When traveling with small cubs, the female must not only safeguard them, but also feed them regularly. While the cubs are small and largely dependent on milk, the female often leaves them in a secluded place and goes hunting sometimes for up to 6 hours. The younger the cubs, the longer they sleep after breastfeeding. If the cubs wake up from being disturbed by other animals (elephants, warthogs, jackals, etc.) or from a running car engine, they begin to whistle, calling on their mother. When cubs reach 3-4 months of age, they spend more time active and often follow their mother while hunting, staying far behind the female when she gets ready for a chase. This helps them learn hunting technics. After a successful hunt and strangling of prey, the female calls the cubs. At this time, it is very important that there are no visual and communication obstacles between her and the cubs (for example, cars with engines and / or radio on). Before or after calling the cubs, the female usually drags the carcass into the bush so that the vultures would not detect it from a height and food competitors from a far distance. She gives the cubs the opportunity to get enough, and only then she herself begins to eat. The soft tissues of the limbs will be eaten first, and the peritoneum will be opened last, because the strong smell of blood can quickly attract kleptoparasites. If the family is not disturbed by other animals, females with cubs stay with the kill for 4-6 hours, periodically eating it. Neema spent two days in search of suitable prey, making an unsuccessful attempts, and in the end, she got an adult male Thomson’s gazelle. Families with small cubs usually spend the next day after eating in dense bushes away from tourist routes. Even when the cubs are playing, they remain invisible from the outside. This is one of the adaptations to avoid attracting the attention of natural enemies.

                   



RANI’s DAUGHTERS are RAISING CUBS

02/20/2021

This year, Rani reached 13 years – maximum age for cheetah females recorded in the Mara since 2012. At this age, she may conceive, but will not be able to bring up offspring. Rani had successfully raised only one litter in 2016 – one male and two females: Nashipai and Neema. Both females became pregnant multiple times, but could not raise litters for various reasons. The advent of 5-year-old Nashipai in June last year with two cubs has become a long-awaited and important event. Today her sister Neema brought her three almost 3-month-old cubs from Olare-Motorogi conservancy to the exact spot of the Reserve, where her sister Nashipai was with her two cubs 15 days ago, and where Imani was with three cubs the day before yesterday. This is not the first time Imani has shared the area with another family. In 2016, when she was raising her litter of three, she coexisted here with Rani and her daughters Neema and Nashipai. Despite the presence of many other predators in this area, it serves as a safe corridor between the Reserve and the adjacent conservancy, and is regularly used by all cheetahs. When cubs reach 2,5 months, the females begin a long journey through the ecosystem, presenting the cubs with new habitats so that they can subsequently successfully settle in the Mara.

           



CHEETAHS and WARTHOGS

02/14/2021

The relationship between cheetahs and warthogs is ambiguous. Female warthogs, called sows, live in groups called sounders, which can contain two or more females with their offspring sometimes of different ages. Subadult males associate in bachelor groups, while adult boars live solitary. Since warthogs have many enemies among predators, they do not miss the chance to assert themselves on cheetahs and chase them away not only from resting places but also from a kill. We observed Nora driven from her fresh kill by the sounder of 4 adult saws, who then ate leftover alongside the jackals. When find resting cheetahs, sows lead piglets towards predators at a close but safe distance, ready to escape at any time. By that introduction of predators to their young, saws teach their offspring how to behave in the presence of enemies. Mature boars and sows without offspring provoke cheetahs, and after a short run attack the cheetah and follow escaping predator for a long distance. When one of the Tano Bora male – Olonyok temporary separated from the group, he was pursued by two adult warthogs, who drove him into a ravine. To date, we have observed only a coalition of five males (Tano Bora) and a female Imani have been able to resist the adult warthogs and not only defend their prey, but also drive the warthogs away. Last week, Imani was able to drive 4 adult warthogs away from a carcass, which she and 3 small cubs ate in the shade of a tree, while Nashipai with her 9-month-old cubs conceded to a group of 2 sows with their piglets.
