If you’ve ever spent a quiet afternoon at a watering hole or driven through the grassy plains of the Waterberg, you’ve likely spotted one of the bushveld’s most comical and endearing characters: the warthog. These “pumbas” are a constant source of entertainment, but if you watch them closely while they graze, you’ll notice a very peculiar habit. Instead of standing tall, they drop down and shuffle along on their front “knees” (which are actually their wrists!) to eat.
It’s a sight that always gets a chuckle from our guests, but in the wild, there is no such thing as a random habit. Every behavior is a clever adaptation for survival.
The Short-Neck Struggle
The primary reason warthogs graze on their knees is surprisingly simple: they have very short necks and relatively long legs. Unlike a giraffe that can reach the highest branches or an impala that can easily dip its head to the soil, the warthog finds it a bit of a stretch to reach the nutrient-rich grass and roots they love.
By dropping down onto their padded front joints, they bring their snout directly to the ground level. This allows them to use their powerful snouts to dig for delicious bulbs and roots with ease, saving them from a very literal “pain in the neck”.
Built-in Protection
You might wonder if all that shuffling on the ground would be painful. Nature has already thought of that! Warthogs have developed thick, calloused pads on their wrists that act like built-in kneepads. These pads are incredibly tough, allowing them to crawl over rocky soil and dry grass without any discomfort.
Always on the Lookout
There is a tactical advantage to this position, too. While they are lower to the ground, staying on their “knees” allows them to remain coiled and ready. If a predator is spotted, they can spring up from this position and bolt into a run almost instantly, usually with their tails held high like radio antennas to signal to the rest of the family.
At Mabalingwe, watching a family of warthogs—complete with tiny piglets—kneeling in a row to enjoy a patch of green grass is one of those quintessential bushveld moments. It’s a reminder that even the most humorous habits in nature are perfectly designed for life in the wild.
