There are no
baby showers, gender reveal parties, or birth announcements when new hyenas
enter our world. Instead, a hyena mom prefers a more private affair, seeking solitary
refuge in a secluded natal den to deliver her cubs. Only when they’re about a
month old will she move them to the communal den, the clan’s hangout spot, to
begin interacting with other cubs and adults for the first time. In the case of
our study clans, they’ll also interact with us humans for the first time. While
there may not be much hoopla in the hyena world when they’re born, the Research
Assistants certainly give shouts of joy when we find new little ones running
around the den.
The first
question we ask when we discover a new cub is, “who is the mother?” because
knowing maternity provides a more complete picture of the cub and its future
prospects. For instance, their rank, which is inherited from mom, tells us
immediately if this cub will have ample access to resources, since high-rankers
usually out-compete low-rankers for access to food. Furthermore, if the mother
is inexperienced (i.e. this is her first cub), there’s a higher chance the cub
won’t survive. An experienced mom is more likely to raise healthy cubs to
adulthood. Once we do know the mother, we can name the cubs in their mother’s
lineage (e.g. brands of syrup, pre-industrial weapons, dog breeds); all of her
cubs will have names within this theme after her first litter. This naming scheme
helps us to remember how the hyenas are related.
To determine
maternity, we have to see nursing. While a female hyena will interact with
other cubs, she will only willingly nurse her own child. Sounds simple right?
Well, sometimes confirming maternity can be quick and easy, but more often than
not, it can be quite a frustrating waiting game. Our North and South clans both
recently welcomed some new members, and determining the mothers was a very
different scenario across the two territories.
Recent rains
coupled with the North den’s swampy location means that observation sessions in
North have been sporadic at best. So when Spencer and Robyn managed to get to
the den a while back and announced there were three new cubs, we figured
confirming the moms would take a while. But the Northies threw us a bone this
time when, after a few dry days, we were able to get to the den. Within ten
minutes of arriving a young female, Anatolian, sacks out and starts nursing two
of our mystery babies and shows us she’s a brand new mom! Almost immediately
after that, Ink, an experienced mom, sacks out and nurses our remaining mystery
cub. It was like we pushed the “That was easy!” button. So, we’re happy to announce
the arrival of Anatolian’s cubs, Momo and Appa (her new lineage is Avatar: The Last Airbender characters),
and Ink’s new baby, Hobbes.
Meanwhile, South
has been quite a different story. We discovered two cubs at the end of
November, and because we could tell them apart, we gave them the cub names
Winky and Dobby. These nicknames are given as a way to refer to the cubs, if we
can tell them apart, before we know the mother. Until we know maternity, we
have no way of knowing the correct lineage and cannot officially name them.
As for
confirming maternity, the South females were not making our job any easier.
Java, the matriarch, has been sitting in the den and acting like a nursing
female for almost two months now. Rangsang, Firefly, Trumain, Rastapopulos, and
Bellagio have all been seen multiple times, sticking their heads in the den,
also acting like nursing females. We really had no good guess as to who the
mothers were.
Then finally,
after a few weeks of wondering, Trumain finally, finally nursed Winky! We’re still deciding on a dog breed name for
the feisty little one. I personally like Newfoundland.
As for
Dobby...we still don’t know. We’ve
seen him/her approach multiple females as if to nurse... and then runs away
into the den. Very anticlimactic and frustrating. So I think it’ll be a few
more observation sessions before we can solve this last motherhood mystery.
As frustrating as they are sometimes, I don’t
think I’ll ever get over the feeling of seeing a sweet, tiny face peering at us
from the den hole. In a place as harsh as the African bush, new life is a
precious thing.
