While African savanna ecosystems are generally known for
their large cats, there are a number of canids to be found here as well.
Contrary to popular belief, hyenas are not among them; hyenas are in fact more
closely related to cats than they are to dogs. Today we temporarily depart from
the world of hyenas, however, and instead explore some of the canids to be
found in the Mara.
Jackals are the most common of the canids running around the
Mara. These small social dogs live in
pairs that breed, den, and raise offspring together. The jackals are
ubiquitously omnivorous, feeding on insects, fruits, and small-to-medium sized vertebrates.
Despite the common misconception that jackals are purely scavengers, they have
been found to hunt the majority of their own food. The two types of jackals
most often seen in the Mara are the black-backed and the side-striped jackals.

Black-backed jackal: The black-backed jackal is the more
social and more aggressive of the two frequently seen Mara jackals. They live
in family groups of breeding pairs with dependent offspring, sometimes with young
adult and subadult ‘helpers.’ They are adept cooperative hunters that
frequently kill small and medium sized mammals. Black-backed jackals have
earned their reputation for boldness by frequently stealing food from much
larger carnivores like lions and hyenas, as well as through their aggressive
defense of their dens. I personally have seen jackals bite hyenas on multiple
occasions! Their comfort around large carnivores makes them particularly well
specialized for open savanna ecosystems, which is their primary habitat.

Side-striped jackal: The side-striped jackal is more
solitary and more nocturnal than the black-backed jackal. While they too live
in family groups, they usually forage alone and at night. As such, they are a
significantly rarer sight here in the Mara. They are more omnivorous than the
black-backed jackals and are found in more diverse habitat covering more of
Africa. Although the side-striped jackal is larger than its black-backed
relative, the black-backed jackal is dominant to the side-striped jackal and
usually wins during disputes over food.
Because of their nocturnal habits, I have seen very few side-striped
jackals during my time here. Recently, we saw both side-striped and
black-backed jackals at a Talek West carcass. Unsurprisingly, the side-striped
jackal kept a healthy distance between it and the two black-backed jackals, who
eventually chased the larger canid away.

Bat-eared fox: The third commonly seen canid in the Mara is
the bat-eared fox. These foxes are characterized by their large ears, which are
used for locating invertebrates, their primary food source. Like the jackals,
they live in family groups consisting of a bonded pair and their recent
offspring. These foxes are found mostly in arid savanna ecosystems and
specialize in eating harvester termites, a lifestyle to which they are
extremely well adapted! In addition to their large, sensitive ears, they also
have thick fur to ward off biting insects and sharp claws to ease excavation of
termite mounds. Their 46 to 50 sharp teeth allow them to quickly chew
potentially harmful insects, and their uniquely muscled jaws allow their
mandible to close five times per second! While these dietary adaptations
are truly impressive, the bat-eared fox’s crowning achievement is its adorable
little face.

While the above-mentioned canids are the most commonly found
in the Mara, there is another dog that can be found in the park: the domestic
dog. Increasingly, we are seeing individuals and groups of dogs foraging inside
the parks boundaries. When taken out of the context of human development and
placed into a habitat full of wild animals, these dogs quickly appear a great
deal less domesticated.

Great photos!
I don't like seeing the dogs inside the park though.
Good post, thanks. Any chance painted dogs might reapper in the Mara?
P.S. It's time for a Cyberman update, good or bad we NEED the news!
