VOICES Ideas and Insight From Explorers
Yvonne de Jong and Thomas Butynski are exploring northern Uganda to study primates, but that’s not all they’ve discovered. See what they found when they lifted their eyes to the skies.
During our field surveys to better understand the primate diversity of north-eastern Uganda, we seek the least travelled routes and those areas for which primates have never been surveyed. During our explorations in February 2015 we encountered many devastating bushfires.
We set out to confirm whether chimpanzees remain in northern Uganda, and which other primates are supported by the magnificent Otzi Mountains on the South-Sudanese border. Here’s what we found.
To help set up effective conservation programs in Uganda, we set out to confirm whether one particular subspecies of monkey was calling this country home. Here’s what we found.
Even when you’re focused on studying warthogs, you can’t help but make some intriguing observations and discoveries about other animals along the way.
Yvonne de Jong and Tom Butynski are National Geographic grantees working to track down what may be Africa’s least understood large animal, the desert warthog.

During a survey of warthogs in northern Kenya, National Geographic grantees Yvonne de Jong and Tom Butynski encounter olive baboons in the very dry region east of Lake Turkana.
The population size and geographical range of the cheetah have declined dramatically during the past 50 years . During a survey of warthogs in Northern Kenya, National Geographic grantees, Yvonne de Jong and Tom Butynski, came eye to eye with this large charismatic cat in the Chalbi Desert, 65 km north of their known current range.
The Somali lesser galago is Kenya’s least known primate. Since 2003, Tom Butynski and Yvonne de Jong have been gathering information on the natural history of this galago. During their warthog surveys in northern Kenya a new population of Somali lesser galagos was discovered at an oasis in the Chalbi Desert.
Kenya’s common warthog, thought to only be active during the day, appears to have ‘swapped’ its strictly diurnal lifestyle for a nocturnal one. In the desert environment of central northern Kenya, food is scarce and there is no drinking water for several months at a time.
