Wildlife Report Singita Kruger National Park Lebombo & Sweni Lodges South Africa Wildlife Report For the month of May, Two Thousand and Thirteen Temperature Rainfall Recorded Average minimum: 9.0 °C (48.2°F) For the period: 10mm Average maximum: 27.7°C (81.8°F) For the year to date: 398.5mm Minimum recorded: 3.0°C (37.4°F) Maximum recorded: 32.0°C (89.6°F) The Xhirombe pride with its welcome new additions The Xhirombe pride of lions, which live in the southern area of our concession, have been going through some interesting times, but the most significant is, without doubt, the new addition three young cubs. This is the smallest pride on the concession, and its heritage is from the famous Mountain pride, but they split years back when the Mountain pride became too big. The previous set of male cubs has now moved off and has become nomadic. The lionesses mated with a new dominant male, seen in October 2012. Given the 110-day gestation period, we estimate these three lion cubs to be at an age of about 3 or 4 months. All members of the pride are in great health – they are fantastic hunters, and rule the mountains. The father is spending a large amount of time with the mother and cubs. Male lions are not reputed to be great fathers, but the dominant male has been staying with the female, and has actually been incredibly vocal of late, sending out a clear warning. The lioness moves the cubs from den site to den site, but the cubs are definitely being exposed a little more now as they get older, and we have been afforded some wonderful sightings as they play around on the already spectacular granophyre rocks, not far from the lodge. Certainly very new and welcome additions to the Singita Kruger National Park. Oxpeckers and their handy uses There are two types of oxpeckers: the more common and highly helpful red-billed oxpecker (Buphagus erythrorhynchus) which is pictured above, and the endangered yellow-billed oxpecker (Buphagus africanus) pictured below. These species both feed on ticks and parasites off animals such as giraffe, Cape buffalo, hippo, impala and many others. Their relationship with the animals is symbiotic, so they tolerate each other – with the host providing the bird with a food source, whilst it is cleaned of parasites by the bird – a win-win situation. But the birds are being put at risk due to human practices, and as a result are restricted to conservation reserves. In agricultural areas where one would expect to find them, with the presence of cattle and other livestock, they cannot be seen anymore. This is due to the fact that livestock are put through cattle-dips and insecticides which are used to keep the livestock in good condition – but thereby killing the oxpeckers food source. Even in the smallest ways, human actions can affect an entire species. There are a few key differences between the two species, despite their very similar size and shape. The red- billed oxpecker, as the name suggests, has a red bill and a yellow eye-ring. It also feeds in a ‘plucking’ manner. This is in contrasts with the yellow-billed oxpecker, which also has red on its bill, but a very prominent yellow base, and the lack of the eye-ring. The yellow-billed oxpecker also feeds slightly differently, with it taking more of a ‘combing’ action. Guides and trackers also appreciate oxpeckers presence immensely due to their early warnings that they afford us. As the birds sit on certain dangerous game species such as buffalo and hippo, if we hear their clear hissing ‘tssskkkkk’ call, we immediately pay attention. They fly up and off the animal, thereby warning the animal and the guide of their respective threats. This has given them the well-earned nickname of, “The Angels on our Shoulders”. The impala ‘rut’ It may be that the impala is the most prominent antelope in the Kruger National Park, but this is well earned. Their ability to feed on both grass and leaves, has allowed them the benefit of being very adaptable to conditions through summer and winter, but also to disperse to many areas. They live in large herds, giving them many sets of eyes to look for dangers. Another characteristic trait that assists with their success is their breeding system. They have a temporary harem structure focused during April and May, peaking between the full moons of the respective months. The bush becomes filled with crazy noises of the males chasing other males out of their territory, and also chasing the females, trying to keep them within their territory. There are ‘jousting’ sessions with impala rams practicing, but also very serious and potentially fatal clashes. The sound of horns connecting with each other is simply frightening. In the end, however, a dominant male emerges and is able to mate with the females in his territory. The females have a seven-month gestation period, and all the lambs are born within a month of each other, essentially ‘flooding the market’. There are only so many impala lambs that the predators can eat, and this creates a very high success rate of lambs, adding to the success of the impala species. The males, when rutting, can put themselves at risk, as they are so focused on the females and defending their territories from intruding males that they often don’t pay attention to potential threats and they become fairly easy targets for predators. The number of impala rams killed during the rutting season does increase drastically. The dominant male also forgets to look after his own condition during the rut as he is so focused on the females and chasing away intruding males, that he can only maintain his dominance for about five to eight days. The next male then comes and takes over, and I guess it could be argued that this is nature’s way of ensuring that the strongest genes are passed on. The above being said, I have witnessed a more humorous incident during the rut. The dominant male was chasing off a challenger, and during that time, the entire bachelor herd ran in and started mating with the females whilst the dominant ram was away. In the end, I guess it might not always be the strongest genes being passed on! The giants of Singita Kruger National Park May has been a great month for elephant sightings on the concession. Receiving good rainfall in both April and especially May has resulted in lush vegetation. This naturally has resulted in good game concentrations. Rivers are still trickling, which is highly unusual, and the elephants have loved this fact, enjoying the great vegetation and water availability during the day, and moving into the Lebombo Mountains at night for a bit more warmth. Large herds of over 30 elephants have been plentiful, with many post-summer additions still trying to learn how to figure out how to use their trunks. The social structure of elephants is a matriarchal structure whereby the oldest and generally most experiences female leads the herd of related females and their youngsters. Bulls sometimes accompany the herd, but are often seen on the outskirts, as they tend to irritate the females. Generally they are out on their own or in small bachelor herds. However, smaller herds often come together in more ‘kinship’ groups, which is what we have clearly been seeing of late. We have also noticed quite a few elephant bulls in musth on the concession, which is always very interesting to see (from a slightly greater distance) as their behaviour is markedly different to usual. The phase called musth is when the big bulls have about six times the normal amount of testosterone in their bodies. They secrete a substance from their temporal glands and leak a combination of semen and urine from their penile sheath. This leaks down the legs and hence their hind legs often appear wet. This is accompanied by a particularly pungent smell, easily recognizable from a distance. The high levels of testosterone make them more aggressive and even their body language changes to a more aggressive ‘swagger’. Elephants are still one of the most incredible animals to watch and seem to have an emotional intelligence far superior to that of many other animals, so we have all truly loved the numerous sightings over May, afforded to us by these extraordinary creatures.

  • MOVEMENTS, HABITAT USE, and ACTIVITY PATTERNS of a TRANSLOCATED GROUP of ROOSEVELT ELK by Matthew Mccoy a Thesis Prese
    MOVEMENTS, HABITAT USE, AND ACTIVITY PATTERNS OF A TRANSLOCATED GROUP OF ROOSEVELT ELK by Matthew McCoy A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science June, 1 986 MOVEMENTS, HABITAT USE, AND ACTIVITY PATTERNS OF A TRANSLOCATED GROUP OF ROOSEVELT ELK by Matthew McCoy A F gam Director, Natural Resources Graduate Program 86/W-66/06/10 Natural Resources Graduate Program Number Ala M. Gillespi9( ABSTRACT In March 1982, 17 Roosevelt elk (Cervus elaphus roosevelti) were captured at Gold Bluffs Beach, Humboldt County, California and translocated to an enclosure 4 km east of Shelter Cove, Humboldt County. The animals were released from the enclosure in November 1982. Data were collected for eight radio-collared animals (seven adult females and one 4-year old male) January to December 1983. The number of herds varied from one (January through March) to four (October through December). Three female herds moved 45 km, 58 km, and 84 km south of Shelter Cove, while the radio-collared male remained within 16 km of Shelter Cove. Home range locations varied seasonally. Home range sizes were largest during the summer reflecting migrational and exploratory movements. Habitat use was disproportionate to habitat availability at the home range level during each season. Cultivated grasslands and riparian areas were used in proportions greater than their availability. Coastal Prairie use was greater than that available except in the Shelter Cove area. Shrub and forest habitat types were generally used less than that available. Animal distances to nearest road and water varied seasonally, but were greatest for radio-collared females during the spring.

  • Ecology and Habitat Suitability of Cape Mountain Zebra (Equus Zebra Zebra) in the Western Cape, South Africa
    Ecology and habitat suitability of Cape mountain zebra (Equus zebra zebra) in the Western Cape, South Africa by Adriaan Jacobus Olivier Thesis presented in partial fulfilment of the requirements for the degree Masters of Science at Stellenbosch University Department of Conservation Ecology and Entomology, Faculty of AgriScience Supervisor: Dr Alison J. Leslie Co-supervisor: Dr Jason I. Ransom December 2019 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Jaco Olivier December 2019 Copyright © 2019 Stellenbosch University All rights reserved ii Stellenbosch University https://scholar.sun.ac.za Abstract Endemic to South Africa, the Cape mountain zebra (Equus zebra zebra) historically occurred throughout the Western Cape, and parts of the Northern and Eastern Cape. However, due to human impacts fewer than 50 individuals remained by the 1950’s. Conservation efforts over the past 50 years have resulted in the population increasing to over 4700 individuals and having moved on the IUCN red list, from Critically Endangered to Least Concern. As there are still many isolated meta-populations, CapeNature established a Biodiversity Management Plan for the conservation of Cape mountain zebra in the Western Cape. In 2001, 15 (six males and nine females) Cape mountain zebra was reintroduced into Bakkrans Nature Reserve, situated in the Cederberg Wilderness Area of South Africa.

  • The Interspecific Relationships of Black Rhinoceros (Diceros Bicornis) in Hluhluwe-Imfolozi Park
    The interspecific relationships of black rhinoceros (Diceros bicornis) in Hluhluwe-iMfolozi Park Roan David Plotz B.Sc. (ConsBiolEcol) (Hons1); GradDipEd (Sec) A thesis submitted to Victoria University of Wellington in fulfilment of the requirement for the degree of Doctor of Philosophy in Ecology and Biodiversity 2014 1 “To Ryker, may the wild places of this world long remain protected to captivate and inspire you” Black rhino near the Black iMfolozi River in Hluhluwe-iMfolozi Park, Zululand, South Africa (Photograph by Dale Morris). “We learn more by looking for the answer to a question and not finding it than we do from learning the answer itself.” Lloyd Alexander 2 ABSTRACT As habitat loss, predators (human and non-human) and disease epidemics threaten species worldwide, protected sanctuaries have become vital to species conservation. Hluhluwe-iMfolozi Park (HiP) in South Africa is at the centre of one of the world’s greatest conservation success stories. The formal proclamation of HiP in 1895 prevented the extinction of the south-central black rhino (Diceros bicornis minor) population. In recent times HiP has been a strategic source population for the D. b. minor range expansion program, facilitating an 18-fold population increase across southern Africa. However, HiP’s own black rhino population appears to be in decline. Evidence for decline is most often attributed to overpopulation and poor habitat quality that is driving apparently significant increases in the average home range sizes, poor growth rates (i.e., low calf recruitment) and poor body condition of black rhino. Other factors such as non-human calf predation and parasitism have also been raised as potential causes of decline but remain untested.

  • Assessing the Success of Red-Billed Oxpecker Translocations As A
    Assessing the success of red-billed oxpecker translocations as a conservation tool in KwaZulu-Natal, South Africa Maryna Jordaan Submitted in fulfilment of the academic requirements for the degree of ecology Master of Science in the Discipline of Ecological Sciences School of Life Sciences College of Agriculture, Engineering and Science University of KwaZulu-Natal Pietermaritzburg Campus 2016 ABSTRACT There are numerous factors that contribute to a bird species becoming threatened and in need of increased conservation efforts in order to survive. Compared with fossil records, current extinction rates are much higher than expected, which emphasizes the need for conservation. Conservation translocations aim to increase the survival of threatened species by ameliorating their possibility of extinction, and contribute either to educational, scientific or supportive purposes in this. Reintroductions or translocations are a well-established method for increasing a species’ distribution and for restoring their historical range. Translocations are defined as human-mediated movements of organisms from one area and released in another. A translocation is only considered successful when a population is self-sustained through breeding of the released individuals and does not require intervention. Oxpeckers are African passerines from the starling lineage. Historically, red-billed oxpeckers (Buphagus erythrorhynchus) had a distributional range that extended from Eritrea to Somalia, through south-eastern Sudan to Zimbabwe and into the former Transvaal, Natal and Eastern Cape Provinces, South Africa. Oxpecker populations became threatened in South Africa in the early years of the 20th century. In southern Africa, red-billed oxpeckers became Near- Threatened as a result of cattle dips with substances toxic to the birds, and because of a significant decrease in their large game host species.

  • The Role of the Ram in the Impala (Aepyceros Melampus) Mating System
    University of Pretoria etd – Oliver, C M (2005) The role of the ram in the impala (Aepyceros melampus) mating system by Colin Malcolm Oliver Submitted in partial fulfilment of the requirements for the degree of MSc. (Veterinary Science) in the Faculty of Veterinary Science, University of Pretoria, Pretoria July 2002 University of Pretoria etd – Oliver, C M (2005) The role of the ram in the impala (Aepyceros melampus) mating system by Colin Malcolm Oliver Project Supervisor: Professor J.D. Skinner Veterinary Wildlife Unit Faculty of Veterinary Science Onderstepoort 0110 South Africa. ABSTRACT The role of territoriality was investigated using 25 impala rams in a site in South Africa. Field data were used to determine known rams as territorial and bachelors, as well as aspirant and indeterminate. The mean territorial tenure was 67.25 days, with a mean territory size of 21.0 ± 11.27 ha, compared to the home ranges of 34.1 ha ± 9.03 ha for territorial and 58.8 ha ± 33.35 ha for bachelor males. Territory boundaries seemed to remain constant through the season, and are smaller when bordering important features such as water holes, which appear to be neutral in terms of territoriality. Mating was observed on three separate dates between 16 May - 4 June 2001, three times by territorial males, the exception being an aspirant ram. The most important diurnal behaviour was feeding, followed by watching, walking, ruminating, resting and licking salt. It was found that bachelors browse more than territorial males, and all males browse and lick salt more in the non-rut.

    WILDLIFE REPORT SINGITA KRUGER NATIONAL PARK, SOUTH AFRICA For the month of December, Two Thousand and Seventeen Photo: Jacques Briam Temperature Rainfall Recorded Sunrise & Sunset Average minimum: 20°C (68°F) For the period: 58 mm Sunrise: 05h08 Average maximum: 33°C (91°F) For the year to date: 464 mm Sunset: 18h44 Minimum recorded: 14°C (57°F) Maximum recorded: 40°C (104°F) In the final month of 2017, we experienced warmer days and the increased promise of rain. The summer sun in the early morning brought with it the call of a multitude of bird species, that were in full song throughout the month. It also got hot very quickly, and the shortage of standing water early in the month meant that a late morning drives back along the N’wanetsi River would lead to regular sightings of zebra, giraffe, wildebeest, impala and elephants coming down to the riverine area for food, water and shade. Impala lambing season is still in full swing, but the young lambs have also now been joined by many young blue wildebeest. We have also had sightings of the odd sounder of warthog piglets. Most of the migrant bird species had arrived by the end of the month, particularly after some rain that fell in the latter parts of December. With the increased amount of standing water, there has been a boom in frog and insect activity, which has in turn, brought locally nomadic bird species from near and far. We are now seeing large amounts of lesser spotted eagles, and white stork, as they feast on insects and most notably, termites as they erupt after rain.

  • Accounting for Intraspecific Variation Transforms Our Understanding of Artiodactyl Social Evolution
    ACCOUNTING FOR INTRASPECIFIC VARIATION TRANSFORMS OUR UNDERSTANDING OF ARTIODACTYL SOCIAL EVOLUTION By Monica Irene Miles Loren D. Hayes Hope Klug Associate Professor of UC Foundation Associate Professor of Biology, Geology, and Environmental Science Biology, Geology, and Environmental Science (Chair) (Committee Member) Timothy Gaudin UC Foundation Professor of Biology, Geology, and Environmental Science (Committee Member) ACCOUNTING FOR INTRASPECIFIC VARIATION TRANSFORMS OUR UNDERSTANDING OF ARTIODACTYL SOCIAL EVOLUTION By Monica Irene Miles A Thesis Submitted to the Faculty of the University of Tennessee at Chattanooga in Partial Fulfillment of the Requirements of the Degree of Master of Science: Environmental Science The University of Tennessee at Chattanooga Chattanooga, Tennessee December 2018 ii Copyright © 2018 By Monica Irene Miles All Rights Reserved iii ABSTRACT A major goal in the study of mammalian social systems has been to explain evolutionary transitions in social traits. Recent comparative analyses have used phylogenetic reconstructions to determine the evolution of social traits but have omitted intraspecific variation in social organization (IVSO) and mating systems (IVMS). This study was designed to summarize the extent of IVSO and IVMS in Artiodactyla and Perissodactyla, and determine the ancestral social organization and mating system for Artiodactyla. Some 82% of artiodactyls showed IVSO, whereas 31% exhibited IVMS; 80% of perissodactyls had variable social organization and only one species showed IVMS. The ancestral population of Artiodactyla was predicted to have variable social organization (84%), rather than solitary or group-living. A clear ancestral mating system for Artiodactyla, however, could not be resolved. These results show that intraspecific variation is common in artiodactyls and perissodactyls, and suggest a variable ancestral social organization for Artiodactyla.

  • Understanding the Behavioural Trade-Offs Made by Blue Wildebeest (Connochaetes Taurinus): the Importance of Resources, Predation and the Landscape
    Understanding the behavioural trade-offs made by blue wildebeest (Connochaetes taurinus): the importance of resources, predation and the landscape Rebecca Dannock Bachelor of Science (Hons) in Zoology A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2016 School of Biological Sciences Abstract Prey individuals must constantly make decisions regarding safety and resource acquisition to ensure that they acquire enough resources without being predated upon. These decisions result in a trade-off between resource acquisition behaviours (such as foraging and drinking) and safety behaviours (such as grouping and vigilance). This trade- off is likely to be affected by the social and environmental factors that an individual experiences, including the individual’s location in the landscape. The overall objective of my PhD was to understand the decisions a migratory ungulate makes in order to acquire enough resources, while not becoming prey, and to understand how these decisions are influenced by social and environmental factors. In order to do this, I studied the behaviour of blue wildebeest (Connochaetes taurinus) in Etosha National Park, Namibia, between 2013 and 2015. I studied wildebeests’ behaviour while they acquired food and water and moved within the landscape. Along with observational studies, I also used lion (Panthera leo) roar playbacks to experimentally manipulate perceived predator presence to test wildebeests’ responses to immediate predation risk. For Chapter 2 I studied the foraging-vigilance trade-off of wildebeest to determine how social and environmental factors, including the location within the landscape, were correlated with wildebeests’ time spent foraging and vigilant as well as their bite rate.
