Our Happy Zebra clan’s den is located very far off-road. When we first arrived at this location, there was a secondary den system that could be found roughly 50m to the South, and this area appeared to be one of our mom’s natal dens (where she birthed her cubs). We kept an eye on this space, but eventually realized that she had cleared out after our initial sighting of her and brought her cubs to the primary communal den. The primary space is actually a network of three den holes (two of which we suspect may connect to each other underground). The area itself is optimal for visibility in a way that North and South clan’s dens are lacking – we are able to drive all the ways around the mound of the den itself, and the grass is relatively cleared out in front of the most active spaces.
See
above for a collection of GPS points on ARGO’s collar. We circled the communal
den in green,
and you can see that ARGO has had quite a bit of movement throughout our Happy
Zebra territory.
We were
able to find Happy Zebra’s den thanks to ARGO (daughter of RUMG, the last known
matriarch), the hyena that we collared in this territory. Based on Happy
Zebra’s current clan list and dominance hierarchy, one would assume that ARGO
is the matriarch of the clan, yet this doesn’t appear to be the case. This
difference in what is officially listed is likely due to the fact that Happy
Zebra clan has been in a period of upheaval since 2020, leading our leadership
team to ultimately decide to cease studying the lower-ranking hyenas. See below
for the official explanation of why (courtesy of Jana Woerner, current PhD
student of Kay Holekamp):
Happy Zebra Clan split into two clans
sometime in 2020 - there was limited sampling due to the pandemic, so the exact
dates are unknown. The hyenas were using two communal dens, one that was
primarily used by higher rankers and one by lower rankers, for several years.
However, there was still regular movement between the two dens and most animals
were seen in all parts of the territory. Since 2020, however, there has been no
movement between the two groups and the lower rankers that split from the main group
only hang out in the Northwestern part of the former territory. We named the
new clan “Not-so-happy Zebras (NZ)” and all clan members that split off are now
marked as NZ Clan hyenas in the Master Hyena List. Their new territory is
located pretty far from our camp and covers a lot of
unknown/difficult-to-maneuver terrain. There has also been very limited
sampling effort in that area since 2021, so most of the new cubs/subs are
unknown. Therefore, we have decided to officially stop studying these hyenas in
August 2024.
Even
though ARGO may not be the highest-ranking hyena, it is apparent that she is
enjoying life from her constant romping and need to play. In fact, on one
memorable morning, we watched ARGO jump about, seemingly ensconced in a fit of
the zoomies, and throw herself backwards onto the ground in an admirable
imitation of a backflip. She is definitely a team favorite here in Serena camp!
Notably,
the space that Happy Zebra clan’s den occupies seems to be a hotspot for many
other species. We have been lucky enough to see pangolins there on THREE
separate occasions, which was an incredibly special set of sightings as they
are notoriously elusive creatures. Additionally, one can find themselves
surrounded by Oribis, Wildebeests, or Elephants when journeying on the track
that we made to Happy Zebra’s den. Overall, it seems like our clan chose an
excellent neighborhood for raising their large brood of cubs.
See
below for some of the exciting outcomes of our observations of Happy Zebra
clan’s communal dens over the past few months:
Above
you can see KRKN with her two cubs GRDN (Garden City Mall) and TIO (The
Junction Mall). KRKN”s lineage is shopping malls in Nairobi.
In
addition to GRDN, TIO, MALA, and VINE we have four more known cubs (mothered by
LANC, JUJU, and THLS). That being said, we believe that there may be more black
cubs that we have yet to assign to mothers!
