The first week of April brought our best chimp observations yet and to think, we were inches away from missing out on the opportunity. If we had stopped to rest before reaching the top of the hill or if that little bitty chimp had moved faster we would have been completely oblivious there were ever chimps at all…well, until we uncovered their city of nests the following week.
There are over 50 km of trails to cover in the Mugiri area. When we don’t have any clues from the chimps we pick a new area of the study site and head there for the day, the following day we check someplace else, and we keep rotating until something comes up. About half of the trails wind up various drainages on the escarpment; the other half follow the Mugiri River and are for the most part straight and flat. Both extremes have their ups and downs. The escarpment trails are steep, strenuous, and this time of the year a slippery muddy mess, but you escape the heat of the lower trails and you won’t be mobbed by swarms of tsetse flies, plus they pass through picturesque patches of woodland forest. By the time you finish searching the escarpment for nonexistent apes you are ready for a few days wandering the level trials along the Mugiri, but only until the tsetse flies drive you crazy, then you are ready to hike off to the hills again.
We were making our rounds as usual, searching one of the escarpment trails, when we just happened to catch a glimpse of teeny tiny chimp struggling to climb down a thick tree trunk as fast as she could. That was all we saw. The adults had already disappeared. Ten seconds and she was gone. A little disappointing to finally see a chimp after a completely chimpless month only to have it flee immediately. Unknowingly though, that little lagging youngster did us a favor. As soon as she was out of view we searched up the trunk into the branches, surveyed out the winding limbs to the leaves, and found what we were looking for: brightly colored, perfectly ripe, Ekebergia fruit. We quickly found ourselves an excellent vantage point and made plans to return the next morning. After weeks of nothing we suddenly had a perfect attack plan. We picked a spot down by the river well below the fruiting tree, where the noise of the water rolling off the rocks drowned out our voices but it was open enough that the majority of the tree was visible and the chimps could clearly see us when they were feeding. From that spot we easily could have snuck up on our target and sat there for hours without being discovered, but the whole process of habituation really relies on them actually being aware of our presence.
Every day over the next week we visited that tree. Each time there were more and more chimps and each day they hung around for a little longer. It seemed like they just kept appearing out of nowhere. Where had they been? Where were they coming from? It didn’t matter; we were finally collecting data and it actually felt like we were finally doing something!

On the fourth day we were observing a group of females with their young for a couple hours when suddenly the tree exploded with chimps. From where we were standing we couldn’t see them enter the tree but they came into view as they moved from branch to branch to feed. We counted a total of 15 individuals! They were mostly females with infants clutching their fronts and juveniles jumping around behind them. Some were more wary than others and fled when they saw us ogling open mouthed at them from below, but others continued eating, grooming, and nursing without paying us much attention. It was just the sort of thing I have been waiting for these past few months. We never wanted it to come to an end. After an entire week of good luck and daily observations we decided to forgo our off day in exchange for another exhilarating day with the chimps. Unfortunately, as we feared, the Ekebergia tree didn’t come with an endless supply of fruit and the chimps and other greedy forest creatures had exhausted all of its resources. We arrived at the same time we had all week but the tree was empty. They had all left. As they usually do, those selfish untrusting chimps moved on without informing us. We were left with no leads to go on. Feeling a bit foolish for being outsmarted again, we reluctantly returned to our usual routine and moved on to another area of the forest, after rescheduling that off day we deserved.

What we thought was a log in the road one morning turned out to be a 6 foot Nile crocodile floating in an enormous puddle. The toothy, scaled refugee wasn’t perturbed by our car breathing down its neck as it languidly slid out of the puddle into full view and casually strutted down the road swinging its elongated tail to and fro. After the amazement factor passed, we weren’t exactly pleased with the discovery of our snappy swimming visitor. Our entire study site is based along a river. We wade through the Mugiri multiple times a day; on one trail there are 13 river crossings in just a few kilometers, on another 28 crossings in 7 kilometers. Crocs are not supposed to be in our river system and are definitely not welcome guests at Mugiri Camp. Luckily, we didn’t encounter the uninvited reptile again, but for the next few weeks every time I saw a poor innocent Nile monitor lizard I shrieked loudly and ran in the opposite direction.
On one of the few annoying occasions we were without a ranger (but didn’t feel like wasting a day doing nothing), Jake and I ventured into the forest on our own to search for the chimps. We made it quite a few kilometers from camp only to discover hippopotamus tracks running up and down one of our trails. We followed the trail of tracks for a while but when we reached a river crossing and the invisible herd of hippos disappeared into the swollen murky water we turned around and headed back towards camp. Neither of us liked the idea of running into one of Africa’s most notoriously aggressive animals, especially one that was misplaced and potentially even more pissed off than usual.
As usual, life keeps happening here at Mugiri Camp, with or without the chimps. When they grant us the opportunity we thoroughly enjoy our sporadic encounters with them but in their absence we make sure to utilize the extra time they gift us to enjoy the forest and marvel at those less evolved.
Cheers from the forest,
Corey & Jake
PS-If you look closely at the second picture, you might notice that the upper chimp is missing his left hand. That's Hunter. He most likely lost his hand due to being caught in a snare trap. Chimps are amazingly resilient animals and Hunter appears to be doing quite well despite the handicap.
