Bateleur (Terathopius ecaudatus) with prey staring_w_7430

            Kruger National Park, South Africa.

The bateleur eagle is one of these mesmerizing birds. The medium-sized eagle is a colorful species and has earned its title as one of the most majestic African eagles.
They demand adoration simply by being present. But many people don’t know the ins-and-outs of the silent predator.
The bateleur eagle (Terathopius ecaudatus) is a fascinating species, and the follwing facts will help you understand why.
1.
The bateleur is a proudly African eagle. The raptor spends its days soaring through the African sky and scanning for its next meal.

Bateleur eagles are widely distributed in Africa, particularly in the south of the Sahara Desert. But unlike many eagle species, they prefer open land to dense forest.

Are you visiting South Africa? The Kruger National Park, Timbavati Game Reserve, and Sabi Sands are a few places that you might strike lucky with a sighting.

While African grassland and acacia savannah are the habitats of choice, it’s not the only place that you can spot the bateleur.

Bateleur eagles are also endemic to certain parts of south-western Arabia. Particularly areas with similar woodland habitat.
2.
Family history can be a funny thing. And the bateleur has quite an interesting family connection. Belonging to the Accipitridae family, the bateleur’s closest relative is the brown snake eagle.

But despite this connection, the bateleur is the only member of the genus Terathopius.

The bird is easier identified by its appearance rather than its family group. The bateleur’s iconic red face (adults only) combined with its pitch-black feathers and grey (sometimes tawny) mantle make it quite a sight to behold.
3.
The bateleur is a magnificent sight in flight. You can even catch a glimpse of their white underwing when watching from underneath. But there’s something extra interesting about their form.

When translated from both Latin and Greek, their scientific name means “marvelous face, no tail”. This translation can be a bit misleading as the bateleur does have a tail. But it’s so short that the eagle’s legs extend further than the tail when in flight.

However, chances are that you’ll be more in awe of their striking face than anything else. The bateleur’s red facial skin and beak are characteristic markings and quite beautiful.

4. The National Emblem of Zimbabwe
Have you ever been to the vibrant nation of Zimbabwe? If not, perhaps you’ve seen their flag? The national emblem of Zimbabwe is a stone-carved Zimbabwe bird.

There is no certainty about which bird the emblem displays. However, the general consensus is that it represents the bateleur eagle or the African fish eagle. What an honour!
5.
If you think that sitting behind a desk for 9 hours is tough, imagine spending the same amount of time hunting for food!
The bateleur eagle typically spends about 8-9 hours each day on the hunt. As scavenger birds, their menu varies to include a wide variety of prey. You may discover a bateleur snacking on mice and birds one day, and an antelope carcass the next.
6.
“Bateleur” translates to “street performer”, “juggler” or “circus performer” and the bird lives up to its name. Acrobatic displays and rocking inflight are typical of the bateleur. Their movement is so iconic that there’s even a bateleur eagle dance.

This behavior becomes even more entertaining during the courtship flight. During this routine,  they exaggeratedly beat their wings.

The graceful bird is a wonder to watch. Their wings are exceptionally long and their wingspan can grow to be 1,86 meters.
While the top of their wings can be black as the night, their underside is white. This makes for a marvelous sight when viewing them from underneath.
7.
Do you want to know how to tell the difference between male and female eagles? Although the same species, the male and female bateleur eagle are different in appearance, also known as sexual dimorphism.
In most species, the males are larger than females. However female bateleur eagles are larger than males. This difference in size is due to the male taking on the role of the sleek hunter. The female’s body supports her role of sitting on the nest for extended periods and appearing large enough to deter predators.
Another key difference is that male bateleur eagles have black feathers on their upper-wing covers and the females’ feathers are primarily brown. This difference in aesthetics is typical of many other species as the male has to win the attention of females for breeding.
8.
Bateleur eagles are ominously silent birds. This makes a sighting even more awe-inspiring.
Although mostly silent, there are occasions when the bateleur will make sounds. In certain instances, the bateleur will produce a loud bark as a territorial display.
9.
After spending so much time in the air hunting, you’d imagine that the bateleur has very little time for anything else. But that’s not the case.
People will often see bateleurs sunning (or sunbathing). It’s not uncommon for the majestic eagles to dip into various water bodies for a bath. They open their large wings and catch some sun to dry off afterward.
They mostly stand upright and straighten out their wings to catch some rays, but they are also known to lie on the ground with their wings spread out. By exposing their wings to sunlight, the oils in their feathers warm-up and improve its aerodynamics.
10.
The reproduction cycle of the bateleur is long and risky. A male and female will mate for life and will often keep the same nest for several years.

The female will lay a single egg at a time and do her best to protect her eaglet once hatched. A typical growth cycle is as follows:

The mother incubates the egg for 55-60 days while the father hunts
The parents look after the hatching for 110 days before forcing it out of the nest
Despite leaving the nest, the eaglet still relies on its parents for food for an additional 3-4 months
Sadly, only 2% of chicks ever make it to adulthood. But once they do, the life expectancy is an impressive 20-25 years.
