Unusual Sightings: Sable research at Vumbura Plains
Wednesday, September 16th, 2009
The latest installment of Wilderness Safaris’ Unusual Sightings comes to us courtesy of Glynis Humphrey, Brian Rode, Onkabetse Mothupi, and Michael Hensman at Vumbura Plains Camp in Botswana:
The sable antelope, Hippotragus niger, has shown some dramatic declines in parts of its range in southern Africa. Despite fairly intensive study in the Kruger National Park and other areas, the reasons for these declines are imperfectly understood.
It is for this reason that an investigation into the home range and habitat use of the species has been initiated in the Vumbura area in the Okavango Delta. Here a relative stronghold of sable exists, allowing an investigation into what factors allow the species to thrive here. Michael Hensman, an MSc student from the University of Witwatersrand and HOORC (being jointly supervised by Prof Norman Owen-Smith and Dr Casper Bonyongo), has just begun his research project using the relatively new technology of Geographical Positioning Systems (GPS) collars to produce fine scale movement data from three different herds.
We have so far managed to fit two collars onto two sable cows and are indebted to the assistance of veterinarian Dr Dane Hawk and gyrocopter pilot Mark Muller without whom the exercise would not have been possible. Dr Casper Bonyongo also lent valuable field experience during the operation.

The sequence of adjoining images were all taken right from the deck of Savuti Camp which looks out over the currently flowing Savute Channel – one of the biggest events in Botswana in recent times. What has been even more interesting is how the elephant population has reacted to this rekindled water source.
As we continue to navigate a treacherous economic landscape, travel providers continue to push the envelope of value with unprecedented deals. Today’s tip highlights one such deal currently on offer from industry leader
There’s no doubt that, given the current economic climate, leisure travel has taken a back seat for many Americans. As a result, tour operators are constantly looking for ways to add value and provide more affordable travel options to potential guests. Nowhere does this ring more true than in the African travel sector as some of the most respected and well known operators in the business are currently running unprecedented promotions.
