One of our our recent Big 5 Safari Tours to the Hlluhluwe Imfolozi Game Reserve we came across a Journey (or Tower) of Giraffe that were very contently browsing the tree tops around us. They totally ignored us and allowed my visitors and I to get great photo and video.
Giraffe Browsing at Hluhluwe Imfolozi Game Reserve
It was fascinating to watch a nearby female as her long tongue (up to 20 inches!) reached out and grabbed the branch she wanted and then stripped the leaves from the branch. She also seemed to keep an eye on us as she did so but at no point was she anxious about us.
