My many years guiding international visitors to the Kruger have provided me with fantastic opportunities to explore some of the aspects of this bigger picture. Some of you will remember these accounts of animal behaviour at a Kill in the Kruger.
A female leopard and her cubs with their porcupine kill and two lionesses at their impala kill.
There were two reasons why we waited two and a half hours for a leopardess with to come and fetch her porcupine kill metres away from our vehicle.
The first reason is that we wanted to see a leopard close up, and the second reason was I knew she would return. This story is about the reasons I knew she would come back and fetch her porcupine kill. Alternatively you may watch the video of it on our YouTube Channel!
She had cubs with her (about a year old) and her success rate for large mammals, (I consider the porcupine as relatively large) is not very good.
Female leopards on territory need priority access to that area’s resources in order to raise their cubs. She is the only one that can ensure the proper development and education her cubs will need in order to survive. The ‘resources’ in her area do not make it easy – in fact they make it extremely difficult for mom leopard to teach hunting techniques, and how to kill effectively – even if it’s a porcupine.
Food defends itself in the bush, and this particular rodent – the porcupine – can make a lasting point about defence. (see; “Leopard Vs porcupine!” video on my YouTube channel) The leopard would have grabbed the head of the porcupine and tried to flip it over - the porcupine would have spent most of its time trying not to let that happen. In this case the porcupine was killed – in the video – the porcupine was successful in defense.
The kill must have happened in the early hours of the morning, we arrived while the mother and her two cubs were beginning to feed – only a bite to the back of the neck of the porcupine was visible. The leopard wasn’t visible but I knew she was still there. I switched off the vehicle and began to wait, this leopard would not leave her kill, I knew that, and a test of who’s resolve and patience would snap first became the waiting game. The odds were in my favour that she would come back while we were still waiting, the sun was coming up and the carcass would soon begin to send out messages to vultures and hyenas. She had cubs to look after and our presence at the kill site would concern her but as time moved on, she would have to overcome her fear of us.
It took 2 hours for the leopard to return the 60 metres she needed to fetch the porcupine. We were still there and my guests got some really good observation – particularly about the patience and ability of a leopard to disappear into the grass 10 metres from you!
Each lioness took their share and panting, crouched over the spoils to eat. That’s when we arrived, along with a lone male hyena that was in the right place in the right time. The lionesses were 10 feet from us when they began feeding.
The impala was barley recognisable after just ten minutes; she was young enough for her skull, vertebrae and other skeletal features to be crushed and swallowed, her skin was peeled away and her hooves bitten off. The lioness with the intestinal stomachs pulled out the rumen, still full of freshly cropped grass and leaves, and with her incisors, split the wall and emptied the contents next to her.
The smell was immediate, sending messages out into the bush. First to arrive were the dung beetles flying in one after the other, landing on the lionesses, next to the lioness and all about the lioness like fighter pilots grounding their planes. They were on a mission, and what a mission – as the lioness was finishing off the last bloody remains – the dung beetles were rolling away their balls of freshly dumped impala stomach contents, across the track and away – the grass was still producing opportunities for life even although it had been neatly cropped by an impala nearly sixty minutes earlier.
My own fascination with what was going on was immediate – as the vultures circled above us I began to understand just how important it was for me to witness this complete cycle of life.
I had a lot of players (the dung beetle was obviously the roll model) all acting out phenomenal sequence of events that I had to interpret for my guests who were all waiting for me to say something.
I quickly assessed some of the things I could talk about;
The importance of grass – as a producer – the importance of the impala – as a grazer (in this instance because it grazes and browses) and the relationship between them – the importance of grass not only as a source of food but also as material for shelters and nesting material, and as this ball of impala stomach contents rolled passed me – as material that would provide a nuptial chamber for the larva of a dung beetle who will eat, pupate and moult into another healthy, fully grown dung beetle.
I could have said that, or that dung beetles belong to the family Scarabaeidae and are also known as scarabs. “They are scavengers, which feed on dung and other decaying organic matter, and play an invaluable role in keeping the veld clean. The ancient Egyptians revered them as a symbol of renewed life!” I said that out loud, and as I did, I thought about the grass again. I kept coming back to the grass! I remembered reading about the digestibility of grass by its fibre content – this time by how quickly the impala was killed by the lion – my guests laughed at the irony, and then one said, “you must talk to us more about grass and its ecology,” and I was impressed – the excitement and action of a lion kill was slowly being worked into the bigger picture…
