As a
Research Assistant, one of my daily responsibilities while out on an
observation session is to record carnivore data. This means that whenever we
find a carnivore in the territories that we study, we document where and when
we saw that specific species. This data allows us to see what other carnivores
the spotted hyena is living around and to record any interactions between them. I’ve
been here four months now and the carnivores I’ve seen thus far are servals,
lions, cheetahs, leopards, banded mongooses, dwarf mongooses, white-tailed
mongooses and side-striped jackals. The most common carnivore spotted in Talek however,
is undeniably the black-backed jackal.
The
black-backed jackal is a sleek, small canine who displays a distinct dark back
coat, pointed ears, and a bushy tail. I think they closely resembles fox species.
What has been striking in the behavior of the black-baked jackal is the observable, strict monogamous bond between
pairs and their intense territorial defense strategies. We often find ourselves in what we
think are black-backed jackal territories and spot a female, knowing too well
that the male is most likely nearby. We often document black-backed jackals in adult
pairs, but have had numerous observations of pups as well. A female will have
litters of 3-4 and interestingly, the assistance of helpers, or older
offspring, has been found to have a direct influence on pup survival. Not only
do helpers contribute their regurgitations to lactating mothers and their pups,
but they spend the majority of their time guarding the den when the mother and
father are away.
If
necessary, a helper will warn the cubs to seek the den’s refuge by barking or
rumble-growling. If a hyena is the danger, adults will drive them away by
nipping at their haunches. Having witnessed this in the field, the ridiculously
quick nipping from the jackal is countered by a hyena’s rapid snap. Together, the
interactions between the species form this fluid dance-like movement between the two with the
occasional squeal and bark throughout. It's quite the sight! One of our hyenas, Toad, a subadult female, discovered a black-backed
jackal den and for weeks aggravated the resident jackals. But to our enjoyment, this allowed us
to observe jackal pups and their parents respond to a hyena’s presence. Having
to record where the individuals are, we stopped and watched the pups explore,
play, and socialize outside the den on numerous occasions before they moved.
The
black-backed jackal is a regular at a carcass session with hyenas. When
together at a carcass, the hyenas are more often than not quite tolerable of a jackal's presence, within reason of course. It’s been interesting to watch
certain hyenas respond more aggressively to a jackal during a feeding than
others, who seem to not mind at all. The civil hyena-jackal relationship is
often tested when a jackal will dart in with remarkable boldness to steal a
scrap, often resulting in a lunge or a snap from the hyenas feeding. That said,
this never stops the black-backed jackals from persisting in their efforts for
a tid-bit or two of a fresh wildebeest, zebra, or cow. When not mooching off
of a hyena kill, the black-backed jackal is certainly an efficient predator,
and of young Thompson’s gazelle fawns in particular.
As parents,
a mother and father display exceptional rearing strategies. Denning in holes
that have been dug by other species like the warthog, the mother will spend
nearly all of her time in the pups’ early weeks of life keeping them warm. She
is then provisioned by a helper or the father with food to sustain her and the young. As the pups age, the family may
move dens multiple times. By around the middle of the third month, the pups
will begin sleeping outside of the den and following their parents on foraging
missions. With continued growth they start to independently hunt and explore
further from the den and by eight months they will have left their natal territory.
Personally, I am always thrilled at
a sighting of a black-backed jackal. Their swift nature, unyielding gusto in
fighting off a hyena from a den, attempts to snatch a bite or two off a
carcass, and all of their other behavioral quirks make them a fascinating
organism to observe here in the Mara.
