During our eight day self-drive through Botswana we camped at Savuti, an area in the central western part of Chobe National Park. Exploring the area during a morning game drive, we found a waterhole and parked the Land Rover there to see who would come for a drink. We waited ten minutes watching a mongoose and a cory bustard, then three impala and a lone sable antelope came to the water and drank. Meanwhile, a large adult male giraffe remained in the cover of the bush nearby with only his head sticking up, cautiously checking us out.
When giraffes spread their front legs and lower their heads to drink, it is their most vulnerable position. So, the large male waited, watching us for another ten minutes before he decided it was safe. When he finished drinking, the rest of the family, the mother and their two babies, emerged from the bush one at a time to drink while the male stood behind safeguarding them from potential side or rear ambush.
