Celebratory Safari


The moon rises as we enjoy sitting around a fire.

The new season kicked off to a wonderful celebratory safari for a well-earned birthday. Two nights in Ngorongoro, three in Serengeti and then a four-day Rwanda trip to see the Mountain Gorillas made for a sweet safari. So here's how we celebrated:
After breakfast on the verandah of the tent, we went for a game drive. Driving around a bush we encountered this impala giving birth- which seemed fitting for a birthday sighting.
The landscapes in northern Serengeti provide a quintessential backdrop to the wildlife sightings in the area. These 500 million year old kopjies provide refuge for lions and leopards. Rock-splitting fig trees (Ficus glumosa) find tiny spaces to establish themselves sending their roots through the cracks in the rocks. Some of them are very old like the one below.
What a perfect tree to have a picnic lunch! The rock at the base was also the perfect table top.

Rounding off the day with sun-downers on a rock with a view.
The celebrations continued in Rwanda with two gorilla treks. Gorilla groups are named after the silverback, the dominant male. We treked to Kwitonda group where this little rascal entertained us for nearly half an hour, and the next day to Agashya group where the weather made it too dark to photograph or film. The Agashya gorillas retreated in the mist and sat in a semi-circle in a cathedral of bamboo.
Kwitonda, the dominant silverback has 4 females and 14 children. He is accompanied by 2 other silverbacks
Gorilla individuals are easily (easily to some) identified by the unique pattern of wrinkles on their nose. By comparing nose prints on the family tree above and the rascal in the video below, I believe his name is Karibu.



Guide Training May 2012

A couple of years ago when I started blogging, I started a blog called Encounters in East Africa to write about some of the exciting little things that we encounter while training guides and on safari. This blog quickly got overwhelmed by another one called Safari Ecology and in all honestly I couldn’t find the time needed to write for three blogs.

Having just spent another 4 weeks with guides in Tarangire National Park, I thought I’d share some of those little things on my adventure blog. Tarangire ranks very high on my list of favorite parks and often I’m asked why I don’t prefer Serengeti for guide training. Of course I’ve been coming here since my first word “dudu” (Swahili for insect) meant any animal including elephants. It’s a classic Acacia savannah habitat and has amazing diversity. It also epitomizes why East Africa is such a unique destination.

A beautiful animal- the Fringe-eared Oryx. The population has declined by over 90% in the Tarangire ecosystem.

When it rains in East Africa, mammals head (migrate) for volcanic grasslands. Soils high in phosphorous and calcium give them the nutrients they need to produce milk for their young. Often these grasslands have very limited water in the dry season so animals then return to permanent water supplies. This results in massive migrations of wildlife. In southern Africa, the older less nutritious soils tend to produce palatable grasses in the growing season, so animals disperse to these areas only to return to floodplains in the dry season, again for water but also for the nutritious grasses found in the flood plains- often described as sweet grasses. I find this distinction between sweet and sour veld quite hard to make in East Africa but it does happen to an extent in some parts of Tarangire. With dispersions and migrations happening in the same place, it’s a great place to study savannah ecology.

The Tarangire ecosystem encompasses the Maasai steppe, which represents an ecological transition zone between Somali-Maasai arid habitat and the more typical Acacia savannas. It is so productive in insects during the wet season that even Northern Wheaters from Alaska fly here in their winter to feed on insects. It is a fantastic place to fatten up for their flight back home. The Maasai steepe is virtually unprotected except for some small initiatives that are successfully working to protect pastoralists and hunter-gatherers’ rights while maintaining these important calving and feeding grounds. It’s a great example to use when discussing human-wildlife conflict and land conversion.

These brilliant blues found in feathers are NOT the result of pigments but the result of a phenomena called Tyndall scattering. The feather should actually be brown because of the melanin in it, but air pockets in the outer layers of keratin refract shorter wavelengths of light- i.e. the blues. 
Talking about melanin- if you have deficiencies you turn out a bit whiter than the rest. Extremes are albinism, but less extremes are referred to leucism.

Precocial is the opposite of altricial. These are not discrete but a continuum. Animals born more able to help themselves are more precocial than animals born that need parental care. One could also learn what nidicole or nidifuge is... A nidifuge leaves its nest when it is born instead of staying for a while- more extreme precocial behavior.

Perfect Safari?

This post is about a safari that happened at the end of February and beginning of March. Having been away from home for nearly 3.5 months things have been hectic in the office and as a result it's been difficult to sit down and write this blog. Tomorrow I head to Tarangire for 4 weeks of practical guide training with a group of great guide candidates. Things have been hectic as I coordinate and advise training that over 160 guides in Tanzania will participate in one form or another. These are exciting times in Tanzania... but more on that later. 

I have selected moments of the last safari to write about, rather than the whole thing, although if one wanted a perfect itinerary, it wouldn't be pretentious to say this could be it. 


Experiencing Serengeti

Part 1

The Short Grass Plains (Day 4 & 5)

We pulled into our camp set up on the edge of the short-grass plains of the Serengeti, laughing over the rocky road wondering how close we were to the end of the world. We were the only guests in camp, a camp I love and have stayed in numerous times in a small concession called Piyaya. There’s a lot more to a camp than the equipment and food that the chefs can produce, and I love this 6-tent camp partly because it’s always just beyond where everyone else goes. Few agents can use it because the experience won’t fit into the predictable boxes of what they can safely sell. I like it because it opens up the opportunity for spontaneous experiences- another thing agents can’t sell and safaris many guides hate guiding. But for a few of us, this is what we love.

The VHF radio crackled and I could just make out the voice of a good friend and guide- Masenga.
Baado niko nao”. (I’m still with them)
Goodluck, another Maasai guide, explained;
Yuko na mbwa”. (He’s with the dogs)

I hadn’t told my guests about the dogs because I get animated when I talk about them and if we hadn’t found them it would have been a huge disappointment. It had been a long day, but guests or no guests, I was going to see the dogs. Postponing the hot bucket showers that were being hoisted up behind the tents, we set off in Masenga’s direction.

In my experience, African wild dogs typically sleep until 6 or 6:30 p.m. before they begin a ritualized and joyful waking up ceremony which involves chasing each other around, begging for food, reestablishing social positions and then a hunt. It was actually a ritual that established one of my own rituals when I worked in Piyaya with Masenga which was to depart for sundowners on a hill around 5:00, glass the wildebeest covered plains with binoculars until the dogs emerged and then follow them as they chased wildebeest across the plains.

Hearing Masenga’s voice on the radio brought back those memories. We set off and the video explains the rest.
 
day 2 and more on facebook
African wild dogs, also known as Painted hunting dogs, are rare. There are fewer wild dogs left in Africa than Black rhino, though no one really knows for certain how many there are. While the loss of wild dogs in Africa is primarily due to land encroachment, they have also suffered at the hands of revengeful pastoralists and game managers who once considered them vermin and would shoot them on sight. They are not feral dogs, and although they belong to the same family as dogs, they belong to their own genus called Lycaon. Dogs, wolves and jackals belong to the Canis genus.

Wild dogs are considered the most efficient hunters on the savannahs and in the miombo woodlands. Hunting cooperatively in packs, they take down prey from the size of hares to wildebeest and zebra. Showing unbelievable endurance, they can run at speeds of 60 km/hr for extended periods of time, wearing their prey down. They catch more prey than any other carnivore especially on the grassy plains of the Serengeti, where they hunt without the tense stalk of the cats, and instead just rush into the herds of wildebeest.

African hunting dogs are particularly interesting in their version of cooperative breeding. Individuals in a pack live within a rank system with an alpha male and female at the top who dominate breeding. Rarely do other dogs in the pack get the chance to breed and if they do they risk losing the puppies to the alpha. The alpha female may have up to 16 puppies that are born blind in a den and begin to emerge after about 2 weeks. This is a taxing time for the other dogs that cannot range as far as normal but must return to the den to regurgitate food.

As I write this, I have received news that the alpha female whelped and two days later lost all the puppies when torrential rains flooded the den.

Having had a wonderful experience with the wilddogs, we set off across the plains through the hundreds of thousands of wildebeest in the direction of Ndutu. Having been alone at the previous camp, it took some time to get used to other vehicles again, but we were rewarded with some great sightings including a cheetah with her 4 small cubs. 



Part 2.
Northern Serengeti

Rounding the Serengeti experience off, we flew to Sayari camp to finish the safari part of our trip alone again. Having spent three weeks there with Nick Brandt (read here), I was eager to find the lions that I’d written about and see how they were doing. Our first drive took us up into the Wogakuria kopjies where we found a leopard and his mother and spent the afternoon watching, photographing, and sipping wine.


Taking advantage of being alone in the area, and the freedom that comes with it, we were up early the next morning and ventured a little further afield with a packed breakfast in the hope of finding black rhino. The only evidence of rhino we succeeded in finding was rhino tracks and the rhino had obviously retired into the dark shade of some riverine thicket where we couldn’t follow. Instead, a courting lion couple allowed us very close.

The landscapes in this region of the Serengeti are stunning and we spent a good portion of the time driving around remarking at its beauty. The wildlife was a bonus, and by the end of the few days there we had seen lions hunting, cubs playing, lions mating and on our last night were rewarded with an iconic view as 9 lioness walked off into the sunset.



Part 3.
Gorillas.

I’ve now written quite a few articles on visiting the gorillas and without using pretentious vocabulary, it remains one of the most powerful wildlife encounters.

The tourism warden joined us for drinks the evening before our trek and we were fortunate to be able to hear first hand about the struggles of managing the national park, but also how important tourism is for conservation.



Requesting a relatively easy group to see, we set off from the car park through the potato fields to try to find the Agashya group. As usual, trackers had already set off in the morning and as we came close to the National Park we were surprised to see the trackers sitting on a rock only a short distance from the famous rock wall boundary. We were quickly briefed on the etiquette of gorilla watching, and were then interrupted by a young gorilla feeding on the wall. After a half hour of watching the gorillas in the forest within sight of the wall, they all moved out of the forest and proceeded to gnaw on eucalyptus bark. It was the clearest I’d seen them and interesting to watch them out in the open.

My Lions


‘Born Free’, by Joy Adamson is the first book I remember reading. I think that it was the book I was being read when I realized I could read faster myself than having someone read to me. I loved the stories of camping in the bush for long periods of time, the adventures of walking and driving through the bush on expeditions, and of course having your own lion to accompany you in the bush. As much of a dream of mine as it was, I never imagined I would end up driving around the bush, climbing rocky outcrops to watch the sun go down, or sneaking up on elephants at a waterhole on foot. I don’t own a lion to take with me on walks, but I work in one of the most amazing places on Earth, and sometimes that’s as good as owning it.
What a treat!
I’m currently in Serengeti for three weeks with a photographer, trying to photograph lions. Lions spend 16-22hrs of the day sleeping, but if you get up early enough you often see them moving around, or at least sitting up. They actually often hunt around 2 p.m. when everyone is back in camp having dessert and getting ready for their siestas.

 
Male lions roar tomake contact with other lions in their pride, and to let intruders know how strong they are. This is the most handsome lion of the Sayari pride. To really appreciate this, you need to plug speakers in or wear headphones.

I started working in this area 6 years ago when I was running Suyan camp, just outside the park. It was a beautiful camp and I have some special memories of walking the area with a couple of Maasai, my teaching them the English names of birds and plants, and their teaching me their traditional uses for plants. The concept behind the camp was to provide opportunities that couldn’t be had in the park like night drives, walks, and sundowners on ridges with bonfires. Sometimes I would convince guests to take the mattresses off their beds and we would arrange them around the fire and sleep under the stars.

Occasionally we would drive across the northern part of the park to the edges of the Mara River. The area had been closed to tourists for a period of time because of a rise in poaching and some violent encounters between tourists and poachers. Resident wildlife numbers were down, but during the dry months elsewhere in the Serengeti, this area got rain and the migrating wildebeest would move in. I won’t go into details of why wildebeest migrate, but I’ve written about it on another blog (safari ecology). Working together with Serengeti’s rangers, and also working in the villages adjacent to the park, Asilia took a risk and put up a camp called Sayari. When Suyan had no guests, I would pop over to Sayari and help out with the guiding. Sayari was a success, and within a couple of years other companies got the drift and now, during the dry season, this is one of the busiest areas in the national park.

Busyness is not necessarily negative, and tourists on game drive are effectively extra rangers on patrol, which makes operating quite difficult for the poachers, so poaching decreased when the tourists arrived. Lions were scarce at that time, as was other game, but the population of wild animals began to increase. It took three years for Asilia to build the first permanent camp here, and in doing so they set the bar for luxury camps in Serengeti. I began coming here in the off-season, when the wildebeest weren’t here, helping out with the walking safaris. Then last year, when I came up in March, I saw over 50 lions here (see blog).  This explosion in the lion population is evidence that there’s also more prey.

Lions live in prides made up of a core of females, usually related. Prides are territorial, and the more females in a group, the more successful they are at keeping intruding prides out, and also expanding their territories when food is scarce. Larger prides also have higher success rates of raising cubs. Males take over prides when they fully mature at about 5 years old. In order to be reproductively successful, a male lion needs to rule a pride for at least 2 years, which is long enough for his cubs to reach independence. This forces lions to form coalitions to keep intruding males out. It is still too early in this area’s renaissance to see much stability, and therefore pride territories and dynamics are ever-changing. However, some of the prides are growing.

The pride above Sayari consists of 2 male lions. Coalitions of 2 males are often not related, though coalitions of 4 or more are. In this case, one is older than the other. There are at least 7 lionesses in this pride and there are 12 cubs that were born sometime mid-December.
 The Cubs.
Such an amazing sight. The mothers killed a zebra this morning in an epic ambush. There will be plenty of milk to go around. These poor two lionesses were being harassed by all the cubs who were thirsty. 

As I follow the pride for the next couple weeks, I will enjoy it on my own for the most part. In a way, it is the dream that I’m living.

Congo III: Volcanoes

The day before we boarded the Rwandair flight to Kigali en route to Congo, I received a link from a friend equally passionate about adventure to a youtube clip from Cai Tjeenk Willink (the Director of Tourism). It was breaking news: sometime in the evening, on the 6th of November, a loud bang was heard marking the beginning of a new eruption. We’d planned to climb Nyarigonga, the famous active volcano that in 2002 had sent a river of lava out of a fissure on the southern side, down Goma’s main street and covering a third of the airport runway. The volcano itself, at 3,468m, has a crater just over a km in diameter, and in the middle sits the world’s largest lava lake. Our plan was to sleep in the cabanas on the rim to enjoy the night view of the glowing molten rock. 

Driving around the south-east of Nyarigonga, we couldn’t wait to see the new eruption. As we glimpsed the first ash and lava spraying into the sky, we excitedly stopped the driver and dragged pelicases and tripods onto the bank of the road to get photos. Little did we know that we’d have fantastic views from the lodge at Rumangabo and the gorilla camp at Bukima. Upon arrival at Mikeno Lodge, we immediately wanted to know if we could walk in to see the new volcano. The delegation of heavily armed rangers had not returned yet from their safety assessment of the area, so Sarah was hesitant to commit.

That evening from the crest of the hill, we watched the earthen firework display light up the sky, and we slept to the sound of the repetitive explosions nearly 15 kilometers away.

Three days later, escorted by 12 rangers, we set off as the first visitors to see the eruption. The path was narrow and overgrown and footing precarious as we picked our way over the lava flows from an eruption that had occurred in 1977. I couldn’t help but notice the prime example of succession; lichens covered the 34 year old rock and in the cracks, moss and ferns had started to grow. Other than that, there were a few pioneer shrubs and small trees that were establishing themselves where enough organic matter had accumulated.

As we neared the volcano, the explosions became louder and our footfalls began to crunch gravel spread by the eruption. The camp was basic, having been carried in the day before when the volcanologist and head warden had walked into the site.  We dropped our backpacks and hurried closer. 300-400m was close enough and we could feel the warmth on our faces. We sat mostly in silence, mesmerized by the sound and sight of the liquid rock building a new mountain. Already in the few days since we’d first sat on the hill watching, a cone had formed. As darkness approached, the explosions became louder and we were showered with light stones. The ambient light faded, and the light from the volcano intensified. We retreated to camp and slept with our tents open, listening and watching as the fountains of lava lit up the sky.
