So, hyenas.
Pieces of the drama of a world hidden continue to unfold.
Some time last week we tracked good old Alice, now about 15
years of age, to the heart of a bush where she was feeding on a dead male cape
buffalo – for the time being, low-ranking Alice had it all to herself. She was FAT, fat and happy. I have always been quite fond of Alice.
At first this was mostly because Eli and Brian called her “Fat ugly Alice”, and
I felt she needed a fan. But now I
love her for her own merit – not caring to be part of the hustle and bustle, a
low profile low-ranker who does her own thing and has the most amazing cub
ever. Poor Alice though, her
reproductive output has been quite awful.
Rebman is her only surviving offspring in fifteen years, compared to
Helios who is only six and has popped out 8 babies, 6 of whom are doing very
well. It pays to be high-ranking,
but Alice isn’t caught up in worrying about rank. Living is enough for her.
Well, we left Alice to her buffalo and continued on to
search for other hyenas. Unable to
find any, we returned to the buffalo, and Alice certainly no longer had it to
herself. The hyenas were
absolutely everywhere, aggressing and squealing and alarm rumbling, and they
were FAT. We have to record into
the DVR whenever a hyena is gaunt, fat, or obese. Almost every single hyena I recorded was fat or obese, out
of at least 30 of them. Amusing
transcribing the notes: “Endor is here, and he is fat. Loki is sacked out, also fat. Titan is obese, Hendrix is obese...”,
and Benson going “Wow” in the background every time we’d see a new hyena, each
heftier than the last. I seriously
cannot believe they could move – it was unreal.
We buried ourselves in the bushes with our well-fed hyenas,
several still gorging, and Eli had me just watch behaviors to learn, rather
than stressing over recording them all.
It was extraordinarily helpful, not to mention terribly
interesting. I had never noticed
the intricacy of behaviors devoted to appeasement: head bob, open mouth appease
(hyena waves its head with its mouth open), submissive posture (a kind of
sideways cower, exposing one’s side to the other while curling around, often
with a “grin” of fear), giggle, back off, ears back, squeal, carpal crawl
(hyena grovels about on its wrists like a feeding warthog). And there are in turn many ways of
asserting one’s dominance, starting with “t1” (least severe) and going up to a
“t3 bite shake”, the most severe.
The t1 aggressions include intention movements, such as an aggressive
look, a stand over (hyena raises its neck as though proud and stands over
another like a statue with its nose pointed downward), a point (hyena
approaches another with purpose and ears forward). T2 includes lunging at another hyena, and half-hearted
motions to bite. The t3 bite-shake
is very unkind, and looks rather painful.
It is just as it sounds, one hyena grabbing a hold of another while
shaking its head. Most times I’ve
seen it the dominant hyena grabs the shoulder of its inferior. Most aggressions are performed while
“bristle-tail,” meaning the hyena’s tail is raised and the black wiry hairs all
fanned out. But you can imagine
it’s absolute chaos trying to discern all of these behaviors left and right
between a bajillion pairs of hyenas who are half-hidden in bushes, not to
mention having to keep track of who is who and who is doing what. Another thing hyenas do, rather
human-like, is take out their anger on innocent bystanders. If one hyena is aggressed upon, it
sometimes turns around and aggresses on another, who has done nothing to
deserve such treatment. I feel
this is because of something akin to embarrassment, or at least a need to
reassure oneself that at least you are still higher than somebody, which that somebody better realize even though they
may have just witnessed you being beaten.
Enjoying the show, learning lots, laughing at Foxtrot (one
of the cubs – I think I remember it being Foxtrot) biting so hard on a piece of
the head while trying to get a morsel that its back legs kept lifting right off
the ground. And before we knew it,
there was only the enormous vertebrae and head of a once live and healthy
buffalo, quite the stinky and impressive sight. I began a final scan, but angry elephant trumpets in the
bushes next door made all of our eyes widen and we cut the scan short and got
out of there. I loved listening to
the DVR and hearing the elephants in the background, before I hear myself say,
“Annnnnnnd elelphants are coming so we terminate this scan and leave.”
I got to draw blood from Hendrix the other morning! We were
up on a hill with homey distant thunder and a rainbow. With Kay directing, I got her nice big
vein on the first poke. Strange
being on the other side of taking blood for once, tapping into physical
diffusion and watching the tubes fill up with liquid. You couldn’t even tell she’d had a needle in her when I
finished, and I still have a couple drops of browned hyena blood on my jeans
from when I pulled it out. I
almost don’t want them washed because the idea of having hyena blood on your
jeans is just too awesome.
Fun times at the den lately! Juno has been sitting in den hole 4 for the last couple
nights, staring out at us wide-eyed through the bushes, praying we don’t
discover the secret we know must be nursing. If only we could see them! She has brought them to the communal den at last. The other two little black six-weekers
have been out some, head-bobbing at everyone and nearly falling over when they
try to lift leg high enough so a big nose can fit beneath to greet them. Amusingly, Sloth (sins lineage) is frequently
sacked out and moves little during den sessions, and his sister Lust might have
better been named Gluttony since we have seen her wandering around with an
empty whiskey bottle! Sloth and
Lust’s older sister Vanity played with the cubs the other night. She is Michelle’s favorite, and I can
see why. Although she is
low-ranking and gets picked on by all the cubs, she keeps returning for more
fun, happy to be accepted into romping with them at any level. At one point Sloth was attempting to
t2-lunge Vanity at the same time Rebman was play-mounting Sloth. As Eli pointed out, it looked as though
Sloth was saying “hold me back!” and Rebman was obliging, as Vanity submissive
postured in fear.
Found two new cubs at Res Den! We think they might be Magenta’s, as we have been picking
her frequency up nearby. She may
have finally moved them from the natal den to where we can find them. About time – they look to be as old as
any of the others, 6 months or so.
We have dubbed them “Garbanzo” and “Chickpea” before we confirm our
suspicion, and so can name them in accordance with Magenta’s “Pokemon”
lineage.
Tracked Moon Pie a couple days ago. She always buries herself in bushes
that you swear a mouse couldn’t fit under, and only leaps up when we are nearly
on top of her. Moon Pie is fairly
easy to identify; her jaw is all off-kilter because she was kicked in the face
by an antelope once while hunting.
She told us what she thought about our disturbing her slumber and left a
smelly treat. After dinner I began
to wonder why I ever enjoyed scraping poop last year. It felt so sciency, yes, but now I have blood work to
satisfy that need, thank you. The
trick is to just not think about what you are doing. And an interesting new fact I learned – some outrageously
high percentage of hyena defecations (of which Eli could not quite remember)
take place between 6:15 and 6:30 at night according to note analysis. What on earth could cause such a weirdo
phenomenon?
Met Moon Pie’s lovely daughter Honey, as well as the male
Hartford. Adding and adding until
alas some day I will have seen them all, and their spot patterns might stop
swimming in my head and settle down solidly beside their names. I’m sure trying! It takes so much practice though. I once asked Benson for a hint when I
was stumped on two subadults, and Nora, Eli and I busted out laughing when his
hint was, “It’s Ted and Cy.”
Thanks, Benson. I can sure
get him laughing over that one now.
Humphries is missing and I am worried sick. He was quickly grabbing my heart and
becoming a favorite, eating right next to the car and looking up at us with big
and sweetly expectant eyes. We
haven’t picked up anything from Samburu’s collar in ages, and I regret
insulting her mothering skills because it seems something has happened to
her. Nature can be cruel, and it’s
the challenge of all challenges for a zoologist to have to know a cub is
starving and be unable to do anything about it. But it’s not the only challenge. The other night we saw Foxtrot and Echo sitting a ways
outside the den, waiting for their mother Drake, but we knew she would soon be
there to feed them. But she
wouldn’t be, and she never will be again.
Two days later during evening obs we received a call from Riz the
balloon pilot. He found her while
out riding on his motor bike. We
expected Samburu, but were told this hyena had a green and yellow eartag,
something only Drake has. We had
just collared her days before, and drove somberly to the darkening and deserted
field above Talek town where she lay.
It is the weirdest feeling having just seen her alive and well, nursing
those two precious cubs only days before, walking about being a hyena,
unusually small and cute Drake.
And now she was lying in a field, with a few hyenas scattered in the
distant bushes, doubtlessly responsible for the part of her stomach that had
been eaten away. We looked for a
spear hole, but found none. There
were no lion bite wounds, no wounds at all in fact, and we were perplexed. Had it been a poisoning, there should
have been other dead hyenas around.
We collected the head and the collar – Eli bravely whacked off the head
of one of his favorite hyenas with a machete, doubtlessly emotionally destroyed
but hiding it well. That’s when
the tears started for me. Maybe it
seems foolish crying over a dead hyena, but it’s not only people who have
complex lives and loved or loving ones to leave behind. Life is so fragile. So amazingly resilient, and yet so
fragile. This time it was fragile.
It was a quiet and gruesomely smelly drive home. We all knew we were going to have to
watch Foxtrot and Echo starve, or at least know that’s what had happened or was
going on. Michelle had stayed back
after the long drive from Nairobi, and she was having a hard time when we
returned, wishing for all the world she could go to the den and return with a
cub under each arm. Didn’t we
all. I kept her company while she
said goodbye to Drake. Kay told me
before dinner this is the hardest part of the job, so I guess I can make it
through the worst.
While cleaning the head today Kay found that the zygomatic
arch was crushed. Drake was hit by
a car.
Bye, Drake.
Sorry to hear about Drake. I think it is totally okay to let yourself be emotional over study animals. You are a scientist and you do your job, but you are still allowed to feel. I always say prayers for the animals that I have had a hand in killing for research. Sorry again for the loss :(
ReplyDeleteThanks Julia! You're the best. I feel the same way, and it's good to have confirmation that I'm not the only one! Sorry it's taken me so long to reply to your comments; I have been having trouble with my internet modem, and so have only been getting on to post my blog, where I haven't seen the comments! Luckily they are sent to my e-mail. Miss you!!!!!
