The Silent Assassin of the Skies: A Martial Eagle Hunt in the Timbavati

It was a warm, partly cloudy afternoon in mid-September, approximately 24 °C, with no predicted rainfall. Ideal for a guided game drive in an open safari vehicle in the Timbavati Private Nature Reserve, part of the Greater Kruger. The Bateleur guests were still buzzing from their morning game drive. They had spent almost an hour observing a herd of elephants, followed by some quality time with 3 relaxed lionesses and their cubs in a dry riverbed. What safari pleasures would the afternoon-evening drive deliver?

Several kilometers above them, an unseen Martial Eagle (Polemaetus bellicosus) soared effortlessly through the sky, its more than 2-meter wingspan optimized for using the thermal air currents to stay airborne for hours while it scanned its vast territory for prey. A member of the Big 6 Birds of South Africa, this apex predator is the largest eagle in Africa and possesses specialized physical adaptations that make it one of the world’s most formidable aerial predators.

The eyesight of a Martial Eagle is roughly 3-4 times sharper than human visual acuity. Its eyes feature a high density of light-sensitive photoreceptor cells and dual foveae (centers of sharpest focus), giving it superior magnification and clarity compared to human eyes. This allows it to spot small prey on the ground from a distance of several kilometers while soaring high in the sky. A prominent ridge above its eyes acts like a built-in sun visor, blocking glare from the African sun and keeping its vision clear during high-altitude hunting. And its lethal weaponry is completed by its sharp beak, long talons, and powerful legs and feet.

A Martial Eagle’s hind claw (hallux talon) can grow up to 5 cm long, which is comparable in size to a leopard’s claw. And it has exceptionally thick, powerful legs and feet – its grip strength is powerful enough to instantly break the bones of large prey like monitor lizards, monkeys, or small antelope. While built for soaring, its wing structure allows it to angle into a long, shallow, high-speed dive (called a stoop) to ambush unsuspecting prey on the ground. Due to both its underside spotting and ferocious efficiency as a predator, it is sometimes nicknamed “the leopard of the air”.

As the Bateleur open safari vehicle drove along Camp River Road, an elegant blur of wings, feathers, and talons flashed down onto the sandy gravel road up ahead. The guide slowed her speed as the vehicle approached the kill scene, in time to see the majestic Martial Eagle fly up into a nearby tree with a Swainson’s spurfowl clasped in its powerful talons.

Also known as the Swainson’s francolin, this chicken-sized, plump bird has short wings and strong legs, built for running on the ground. Many safari visitors to Southern Africa have derived great amusement from the speed and comical agility of these birds, as they frantically run ahead of the game-viewing vehicles on the sandy gravel roads for extended periods, when it would seem far simpler and wiser to flutter or stumble to the side. But, like many mammals, birds, reptiles, and even domestic livestock that are blessed with far greater stature and body mass, the Swainson’s spurfowl is simply no match for the silent assassin of the skies.

Recent Wildlife Sightings in the Timbavati

The third week of September started with the discovery of the Mayambula lion pride on a giraffe kill during the morning game drive. The delighted Bateleur guests immersed themselves in extended periods spent watching the lions feed and interact with each other, with the ever-hopeful hyenas never too far away. By the following afternoon, the lions had moved off, allowing our guests to enjoy a high-quality sighting of 10 hyenas devouring the leftovers.

Two days later, it was the turn of the Sark lion pride and their cubs to provide extended photo opportunities, feeding on their blue wildebeest kill right next to the road. They were still there the following morning, hungrily watched by a committee of vultures. Once the lions had eaten their fill and wandered off, the scavengers were left to fight over the leftovers. The unfortunate vultures were beaten to the prize by a clan of hyenas, which was last seen carrying the remains of the wildebeest carcass off down the road in search of a quieter dining area.

The enthralling lion encounters continued throughout the week. We enjoyed the spine-tingling moments when 2 male lions chose to announce their presence to the Timbavati by roaring in concert with each other, right next to the vehicle. We watched 3 lionesses stalking impala at Marco’s Dam before they were chased off by an angry, territorial hippo bull. And, on one of the bush walks under the watchful eyes of our experienced guide and tracker, we enjoyed a long visual encounter with 4 lions.

The Bateleur guides and trackers repeatedly put their extensive knowledge and experience to good effect during the bush walks, allowing our guests to track and enjoy safe and high-quality sightings of lions, buffalo, a breeding herd of elephants, and a rhino cow with her calf. Those were bucket list experiences for many of our guests!

The spotted big cats were not to be outdone by their tawny counterparts. Three cheetahs spent a few days in the area and provided a few excellent sightings. We first found them in the company of a tower of giraffes, with a couple of jackals in tow. The following morning, we found them in the same area and enjoyed a beautiful sighting of them frolicking together. Two days later, they were back again, and we were able to follow them as they went on the prowl for their next meal.

At first, the leopards lived up to their reputation of being highly elusive. But a beautiful sighting of a very relaxed female leopard was followed the next day by an encounter with a very skittish female in a tree. We saw a big male near Marco’s Dam and then had the pleasure of observing another male in a tree as he fed on an impala that he had recently killed.

In addition to a plethora of plains game, the Bateleur guests enjoyed several sightings of rhino and were treated to a literal abundance of both buffalo and elephant. One group spent about 30 minutes with a breeding herd of elephants that had a tiny calf in their midst, always surrounded by the adults to keep would-be predators at bay. And another group spent time at Nyala Pan watching a herd of elephants bathing in the mud.

Having observed 3 of the Big 6 birds of South Africa earlier in the month, we were treated to two magnificent sightings of Martial Eagles in mid-September. The first involved that breathtaking capture of the Swainson’s spurfowl as we set out on an afternoon game drive. Two days later, during a morning game drive, our guests watched another Martial Eagle fly in low to catch a small game bird, before proceeding to pluck its feathers and feed on a nearby perch.

There is an ever-present battle for survival in the Timbavati, especially for the wildlife and birdlife that is lower down the food chain. But during some periods, that reality is more evident than others. This was one of those weeks!
