This morning we came across a nice tasty wildebeest carcass with some subadult (ie. teenage) hyenas feeding on it. As far as carcass feeding goes, this was a pretty calm morning for the hyenas (No one got bullied over food TOO much). Really, the drama surrounding the carcass was ALL jackal drama, which inspired me to write a something about these gutsy little dudes.
If we find lions or hyenas feeding on a carcass in the Mara,
we are very likely to find some diminutive jackals running around in the
background. While the larger predators are often busy fighting with each other,
the jackals can often fly under their radar, darting in and out of the group
feeding on the carcass and grabbing small scraps.
These jackals were agile enough to grab some scraps despite
the annoyance of the hyenas.
They are surprisingly gutsy with larger predators. (Keep in
mind, jackals are the size of a small fox (~ 13-33 lbs), as opposed to lions
(~ 240-400 lbs) and spotted hyenas (~ 100-180 lbs). Recently, I saw an injured lioness
guarding a carcass from a couple hyenas. She lunged at the hyenas, who promptly
ran away, giggling frantically. After that, a lone jackal jauntily ran up to
her and stared from a few yards away. After a few minutes of a stare down
between the two, the jackal finally thought better of it. Still, he/she made a
better show of it than the hyenas.

Some extra reasons jackals are
excellent:
They’re survivors – Jackals basically eat
whatever whenever, which makes them successful in areas where other carnivores
may suffer. While they’re definitely game for carrion, it only
makes up 3-18% of their diet in the Serengeti. They also eat
insects, rodents, snakes, baby antelope, and will start adding more fruit to
their diet when vulnerable prey are hard to find. They can even do very well in areas with lots of humans, because they
will happily eat our trash, scraps, and (sadly for the farmers) small domestic
animals.
They’re wily- The
will follow hunting lions and wait for them to make a kill, then dart in and
grab some food. In the Kalahari Desert, they will also follow brown hyenas, who
are extremely good at finding carrion, and try to pilfer off them.
They’re always game
for a fight – At our carcass this morning, the jackals spent a good portion
of their time attacking the vultures and marabou storks, large scavenging birds
who were also trying to nab some food. We even saw some of the jackals jumping
in the air after the birds when they tried to get away.
In the Kalahari, jackals have been known to play “tug-of-war”
with brown hyenas, with several jackals pulling at one end of the carcass while
a hyena pulls at the other. They’ve even been known to nip hyenas on the bum
and dash in to grab a scrap when the hyena whirls around to attack. I myself would think twice before nipping a hyena on the butt, but
not jackals...
We had a little bit of tug-of-war going on this morning:

The jackals that
fight together stay together: Jackals are generally monogamous – staying
with the same partner for years. Together, they will defend their babies from
hyenas by nipping their haunches, defend their territory from other jackals, and
hunt together.
If two jackals hunt together, they can take down a baby
antelope 67% of the time, even if mom is defending it.
And, of course, they
are adorable:
