What do north clan hyenas, south clan hyenas, and a lioness have in common?
THEY ALL WANT THE ZEBRA CARCASS.
Yesterday was a pretty exciting morning. It started off
quiet; we went to the South clan’s den where we saw Java, south clan’s
matriarch nursing one of her cubs. Toledo, south’s alpha male was also resting
close to the den. There was one other subby looking hyena wandering around that
it took us a little bit to ID, but I soon recognized him as Lunch Lady, a young
male hyena from North clan. We’ve never seen him in South clan before, but the
way he was chilling with Java and Toledo made it look like he was already well
accepted. Lunch Lady is part of the "professions" lineage; his mother is Sherman.

Male hyenas almost always disperse from their natal clan
between the ages of 3 and 5 and join a new clan in search of mating
opportunities. It usually takes some period of time before they’re fully
accepted by the hyenas in their new clan and they’ll join as the lowest ranking
hyena. I’ve known Lunch Lady since he was a little cub in North clan chewing on
the car, so it was really exciting to see that he’s most likely joined South
clan.

As it started to get light out, Lunch Lady started to wander
away from the den. We followed him and gave him some inhibitory control
cylinder trials and some multi-access box trials on which he did great! Lunch
lady is now the fourth hyena in Serena to open up the box. Interestingly, he
used the push flap by pawing at the box with his front paws. He’s the first
wild hyena to use this solution!

After doing trials with Lunch Lady we did a prey transect
and then drove through North territory to get back to camp… that’s when we saw
a mob of hyenas that we quickly recognized as South hyenas just inside of the
North territory boundary! This group included Lunch Lady as well as natal South
animals Palazzo, Nali, Star, and Seabiscuit. We followed these guys to a zebra carcass that North hyenas were chowing down on. Two other south immigrant males, Strummer and Slim were also born in North clan and were seen feeding with North clan despite being well accepted into South clan.
Slim, a South immigrant male who was born in North, excitedly approaches the zebra carcass with a few other South hyenas.

Strummer, a South hyena who was born in North, feeds on the carcass with other North hyenas.
Oakridge, an immigrant male in North clan, is covered in blood as he feeds on the zebra carcass.
This was a clan war over the zebra carcass!! Two South hyenas, Taylorsville and Onekama were extremely drenched in blood which
made Mike and I think that they killed it and North clan had run them off it.
Clearly, Taylorsville and Onekama had called in reinforcements because more and
more South hyenas were showing up by the minute! South clan charged the carcass
causing the North hyenas (Oakridge, Ypsi, MrsB, and Kath) to scatter.
Taylorsville's face was black with blood. Maybe he killed the zebra?

This South hyena was literally foaming at the mouth.
When South clan charged the carcass to take it back from the
North hyenas, Slim, with the help of Onekama, ran off with a zebra leg. A few minutes later, Strummer ran off with a second zebra leg. All three of
these South immigrant males retreated into South territory while the rest of
South clan beings to feed from the carcass.

Interestingly, Lunch Lady was not allowed to feed at the
carcass despite his good relations with Java and Toledo at the den. Lunch Lady
actually seemed quite confused about which hyenas were supposed to be his
friends and which his enemies and attempted to socialize with both South and
North hyenas. Immigrating to a new clan can be confusing! A male hyena has to
learn the identities and ranks of a brand new clan of hyenas which can number
from 30 to over 100 individuals!

Anyway, South hyenas started devouring the carcass when… a lioness
explodes out of the thicket growling and sends South hyenas scampering for
their lives. She takes one look around, decides there are WAY too many hyenas
for her to deal with and promptly walks back into the thicket. Now this is not
only a clan war, but a lion-hyena interaction!
Video of lioness charging (my apologies for cutting the audio, there was some inappropriate language due to surprise from myself and Mike).
Some rangers that we talked to after the session said that
she might be the lioness who has some babies in the area. We didn’t get a good
look at this one, but we did see a heavily lactating female a few days ago.
Lactating lioness.
South hyenas retained the carcass after the lioness
retreated, but five minutes later North rallies and chases them off the carcass
again. At this point there were about 4 North hyenas and 7 South hyenas
(including Lunch Lady as a South hyena). By this point the South hyenas seemed
pretty full and they did not try to take the carcass again. Interestingly,
Lunch Lady continued to feed with the North hyenas and when they finished
eating he followed Ypsi back into North territory. It seems like he’s not
completely part of South clan yet and is still associating with members of his
natal clan!
Great post, what an exciting day for you all! Thanks for sharing.
