In the eighties, when we  lived in Kenya, many people regarded the Nairobi National Park (NNP) as a large zoo next to Nairobi. I must admit that for a while I belonged to this group. I did not think that to see the Jomo Kenyatta Conference Centre (the tallest building then) from the park was a nice sight.
After a couple of years, again Paul, luckily convinced me of its value and I realized what a great privilege it was to have such a large area of wilderness a few minutes drive from our houses! So, following his advice, we bought a one-year pass to the park. The pass was stuck on our Land Rover windscreen and it enabled the car (and its occupants) to visit the NPP as many times as we wished!
It soon became one of our favourite places to visit! We also brought lots of people  there. Often we would collect our guests from the airport and drive through the park (in through the East Gate and out through the Main Gate). During the drive across the East African plains guests had a chance of encountering a number of interesting animals only hours after arrival.
Except for elephants, the park would offer all other animals that you wished to see in Africa. As far as I recall, although we saw a Serval cat we never spotted a single leopard there over the many years we stayed in Kenya. However, there was much compensation, as you will see.
As mentioned earlier in this blog  it was the first “field visit” I did with my late former boss Matt. In addition to visiting it with Paul, we also went there very often with Luis, another good safari companion from Argentina with a passion for bird photography. With him we also shared a few rather late (some very late!) departures from the park after having overstayed watching some interesting event! I must add that the rangers were very kind to us and finally accepted our obvious excuses such as an engine malfunction or a puncture! We never slept inside the park!
My first kill as seen it in the NNP when I first went there with my former boss, the late Matt.
Normally, the best predator-prey interactions start taking place when you are told to leave the place so, overstaying was the only way that we were capable of watching lion hunting while the light faded and eventually night fell. Although it often got too late to watch the complete act, we were lucky to see some interesting things. Excuses related to engine malfunction and punctures worked for a few times. However, as the rangers started to know us, they tolerated our tardiness!
Luckily, there were also interesting happenings during daytime. It was at NNP that we had our first encounters with black rhinos that were not hard to find once we learnt where their favourite browsing spots were.
The now rare black rhino as seen in Amboseli National Park.
Late mornings were also interesting as the resident cheetahs would be looking for their favourite prey, the Thomson’s Gazelles. With patience, we were privileged to observe them hunting at speed in front of our eyes!
There is nothing like visiting a place frequently to get a good idea of where the potential for action was.
Hippo Pools was not only attractive due to the resident hippo and the sightings of the rare African Finfoot (Podica senegalensis) but also because you could leave your vehicle and walk along the river, although this exposed you to some close encounters with naughty Vervet Monkeys and Baboons. Although now it seems funny, I still vividly recall my first visit when stupidly (to be mild with myself) I was carrying some bananas as snacks and, after no more than two steps a rather large baboon surprised me and easily took all the bananas before I could even feel scared of the surprise assault by my primate cousin.
Often we enjoyed a few picnics at the main viewpoint followed by short siestas overlooking the Leopard cliffs or the Athi River towards the South of the park. As it was hot, often the windows or sliding door of the kombi would be open. This was the usual procedure until I stopped. It happened one day that my wife was not reading in the front of the car as usual but she was watching the leopard cliffs some distance away from the car.
That day I did not wake up normally but something interfered with my slumber. On guard, I stayed quiet but I could hear noises inside the car and smell something strong! Immediately I realized that a few baboons surrounded me! The moment I moved and shouted at them, mayhem followed! They all tried to get out through the open window at the same time with the consequence that I witnessed a short baboon exit jam! Eventually, after a lot of jumping, screaming and scratching they escaped but not before leaving behind the consequences of their fright… and some of my money went into a good car wash!
In two instances we saw lions hunting warthogs. The first one was as soon as we entered the park through the East Gate. A lioness was clearly hunting on the road and as she started scurrying we saw a warthog running for its life a few metres ahead. We stopped to watch as the lioness was closing in on the fast running hog. The moment the lioness was about to grab it she tripped and fell heavily on her back while a very scared warthog disappeared in the tall grass! As events unfolded too fast for me, I only managed a bad picture of the lioness after she sat on her haunches to see the warthog run away!

The second time the warthog was not lucky and, from the main viewpoint, we watched a lioness stalk its prey near the small dam. She caught it and killed it fast and then she left it so we managed to get quite close and -through the binoculars and camera zooms- see the teeth holes she made on the animal’s neck. Before the hyenas could find the warthog she returned with her two young cubs.
Another, more personal, encounter with a lioness took place under very different circumstances. At the time we lived in Tigoni, about 35km away from Nairobi and, as my wife worked in the city, everyday after work I came from Muguga to collect her to go back to Tigoni. The day in question there was an important donor reception at Duduville, the International Centre for Insect Physiology and Ecology HQ located in Kasarani. It was clearly too far to go back home to change our clothes, get back for the function and home again at night so I hatched a clever plan: after picking up my wife we would drive to the NNP to kill time and change into our formal clothes there.
As planned, we entered the park in late afternoon and we stopped in a discreet area to proceed with our clothes change. While my wife was dressing up in the car, I got out to change my trousers! In the process I moved a short distance from the car with such bad luck that I walked straight towards a lioness that was resting -possibly sleeping- under the cover of a bush!
We shared the shock of the encounter. Seeing me attempting to fit in my trousers, the lioness took off and it was out of sight in a flash while I, holding my trousers as well as I could, managed to get into the kombi. “What are you doing?” said my wife that, focussing on her make up by means of the rear view mirror, had missed my critical encounter. “Lion” was all I could gasp while trying to recover from the scare. This was the first and last attempt at changing clothes in the NNP.
Among the herbivores, the giraffes were unique as they browsed on the various acacia species present and a number of hourglass trees confirmed their presence.
However, it was the buffalo that were very interesting. I believe that there was one herd of buffalo and the first time we found it we noted that they not only were very tolerant of vehicles but also very curious. Their curiosity reminded me of our steers back in Uruguay. We soon learnt that if we stopped the car and waited they would come very close to inspect our car. Although they never touched it they did smell it and spend quite some time very close to us.
This was repeated every time we saw them and it enabled me to observe them at close quarters. During the dry season they carried very heavy tick infestations of the Zebra ticks (Rhipicephalus pulchellus) and the poor creatures used the whistling thorn bushes in an effort to dislodge them.

So, naturally, whenever we saw the buffalo we did our “buffalo trick” and waited for them to surround us without thinking much. So little we thought about it that when two lady friends from Uruguay came to visit for their first time in Africa, we took them to the NNP after the airport and that time -luckily- we found the buffalo. As a couple of hundred of these rather large and fierce-looking animals started to approach us, nervousness increased and comments started to flow. “What are they doing?”; “Julio, they keep coming”; “This is not dangerous?” and others until they openly showed their alarm and started charging me with “attempted murder”! To their relief, after a short while, I started the engine and the herd moved calmly away while we left them, taking with us two very agitated friends! Many years later they still remembered the experience as one of the most exciting they have ever had in their lives!
Several birds nested in the park and migratory storks and kestrels would visit on their way to their final destinations. Apart from Crowned cranes and Ostriches at least a pair of Secretary Birds, my favourite bird of prey, nested at the NNP. These birds -nowadays quite rare- had built a basic twig platform on a rather low bush. Their location enabled us to see their fledglings being fed and to follow their progress until they were eventually able to join their parents criss-crossing the savannah areas of the park in search for snakes and other prey.
Two rather unlikely finds have remained in my mind up to today. The first one was the sighting of a large carcass on a small hill. Nothing unusual about finding animal remains in a National Park you may rightly think. I would agree with you fully except that the dead animal did not match any of the park wild inhabitants! The remaining hide was uniformly brown with some long hairs. Luckily, despite its decay, the examination of the remaining bones revealed that it was a horse!
At first I tried to convince myself that it was impossible but the find could only be an adult horse! Only later I realized that I had veterinary colleagues that kept riding or polo horses in residential areas bordering the park and, the same way that lions often got out of the park and caused problems for the residents there, I am convinced that a horse somehow entered the park and it was killed.
The second encounter was mentioned in my earlier blog . We came to an area the size of a tennis court looked as if it had been ploughed. Curious we continued driving and scared a couple of lionesses. As things were getting interesting we continued and almost bumped into two massive dead male buffalo. The first thought was that they were killed by lightening but it was the wrong season for this! Again, looking more carefully they were facing each other and, although already decomposed, the position of their horns indicated that they were locked!
We then not only understood the earth scars but started to speculate on the cause of death. The most likely scenario was that they got exhausted from fighting and succumbed to stress combined to lack of water and then the lions found them and took advantage of the situation to fill their bellies! We will never be sure of what happened but it had all the signs of a mighty struggle.
So, these are the few anecdotes I recall from our amazing time we spent at this great place.
 Every time I reminisce (when we …) about our African past I remember that once I heard that people like us belonged to the “whenwe” tribe. Looking for this now, I learnt that the name was given to the more nostalgic members of the 1980’s arrivals from the then Rhodesia to South Africa. See: https://newint.org/features/1986/01/05/briefly
 Apart from friends I did this trick with donors visiting our projects. I still believe that this “introduction” to the country improved our funding!
