The weather here has been unusually bad the last few days. Non-stop rain and very cold. So we haven't trapped any animals in a few days. However, before the rain descended on Nyungwe, we were lucky enough to catch a young jackal in one of our larger traps. Jackals are closely related to dogs and are opportunistic carnivores that feed on small mammals, birds, reptiles, and other prey items like insects. Initially I was very excited that we finally captured a jackal. But after sedating her and giving her a physical exam, my excitement turned to sadness. She was only about a year old (5.5kg) but had a serious snare injury to her right front paw. Her leg was broken at the wrist, and the pad of her paw was seriously mangled- only two of her five pads of the paw remained. She had an obvious snare scar just above her mangled paw, and above the scar, her wrist was bent - clearly fractured. I don't know what her chances of surviving such an injury are, but I suspect they aren't great. Jackals typically hunt by pouncing on their prey, and with one of her two front paws being useless, I don't see how she will survive in the long run. I couldn't help but wonder if maybe that was why she was in my trap at all (ie. hunger).
It is becoming increasingly clear that the plight of Nyungwe's carnivores is not a priority in Rwanda. For one, carnivores are elusive and nocturnal, tourists or locals rarely see them so they can't be used to bring in tourist dollars into the country. One hears much about the state of gorillas and birds throughout the world, but the plight of poorly studied carnivores in these remote mountains, where it is almost impossible to see these creatures, is not on anyone's mind, even those government and NGO agencies responsible for conservation.
Studying carnivores can be difficult and frustrating work — people are generally either afraid of carnivores or generally dislike them because they can prey on their livestock, so there is little incentive to protect them. Poachers can receive either much-needed protein from hunting carnivores or money for selling snared wildlife in remote villages, or more likely, across the border in the DRC, a mere 40km away.
This is not the first snare injury I have seen. My camera traps have captured images of other jackals with snare scars on their wrists. And these are just pictures of animals that survive- I'm sure there are many more of the smaller carnivores that aren't able to free themselves from the snares of poachers. It's also interesting to talk to locals about carnivores here. Some people boast that they have seen leopard and golden cat (the two most elusive carnivores that have existed in Nyungwe in the past- now it is not clear if they have been extirpated here or not). Yet, most of the people I talk to aren't able to even differentiate between even common, non-carnivore species, like primates.
For example, my two students from NUR came to work here for the last month on their thesis projects. I received a call from them one day as they were going to check their traps that they had run into "monkeys" blocking the trail. I tried to ascertain what species of monkey (there are 13 species here and only one is aggressive, the olive baboon). They said they didn't know what species it was, only that it was grey. I asked for other descriptions (are they in the trees or on the ground? How big are they? How many?). The students were petrified of the animals and could only tell me some vague details. I told them to hang out and see if the troop moved away, otherwise they could eventually clap their hands and slowly approach them. I received a text an hour later saying they (the monkeys) hadn't moved and they were too afraid to approach them. To make a long story short, the monkeys turned out to be olive baboons. Which can be aggressive if you are 1) a stupid tourist who tries to get too close to take a picture, or 2) a stupid tourist/local who tries to feed the animals. But otherwise the animals are fairly mild mannered and given a respectful distance, pose no real threat. But what struck me wasn't what species they were, so much as my undergraduate biology students, one of whom grew up at Akagara National Park (where there are tons of baboons), couldn't identify them, even though theyare extremely common in Rwanda.
So if Zoology students aren't able to identify one of the most common primate species found in Rwanda, then I don't rely too heavily on the ancedotal "sightings" of leopards and golden cat that I have heard about in Nyungwe. For one, leopards look a lot like serval (large spotted felid), and solitary cats are amongst some of the most elusive of carnivores to ever see. There's really no telling what carnivore species remain in Nyungwe. I can tell you however, that if you go to websites endorsing tourism at the National Parks in Rwanda, you'll be surprised to know that these websites say that tigers, yes TIGERS, are in Rwanda!! Tigers are in India and other parts of Asia. See for yourself: http://www.akageralodge.co.rw/games/wild%20activites.htm
I'm hoping that my camera trapping might begin to shed some light on whether some of these rarer carnivore species exist, and what habitat they prefer. Perhaps this data can be used to encourage further conservation measures in Nyungwe - specifically, to protect wildlife from illegal poaching. Because while no tourist will ever likely see a wild leopard at Nyungwe, they still remain one of the more charismatic carnivores (after lions) that persist in Rwanda, and perhaps knowing they exist might draw some tourist dollars to this part of the country. Unfortunately, it seems that money is the only real incentive for developing conservation plans in most of Rwanda

Arusha and after
Was in Arusha, Tanzania for the Association of Tropical Biology and Conservation conference last week. It was such a fun trip. We went on a day safari to Arusha National Park and the conference itself was really interesting. I presented some of my preliminary carnivore data and met lots of really interesting scientists conducting research all over the tropics.
We returned to the field on Sunday and resumed live trapping. Our first day back we caught another genet. This guy (okan named him Scrappy because he was kind of older and scrappy looking) was an adult male.
Earlier this week, we went to the middle of the forest to deploy more camera traps. One of my undergraduate thesis students came along too. We began by crossing over a very high canopy walk in the forest which was amazing. We hiked a very hard trail (6 hr hike over 1000m in altitude) and I was really hoping a magical helicopter would come rescue me about 5 hours into the hike- three hours were hiking straight up 1000 m in altitude. BRUTAL! And I wasn't even carrying a heavy pack! Okan was carrying the camera traps, and as usual he was just skipping up the mountain. The hike was really beautiful and there were 5 different waterfalls along the way.

Okan conquered his fear of heights on the canopy walk
Nyungwe Forest near Uwinka (middle of forest)
The first of several waterfalls
Aloys and I at the waterfall
More waterfalls!
Okan and I resting at the bottom of the valley (3 hours into the hike) at one of the last waterfalls
Okan is staying in Butare now to do some work and I have a friend coming out to help me in the field for a few days. I only have another 8 days of trapping until I finish at my current site. Then I will close the traps and I have two friends from NYC who will be coming for 2 weeks in early July for a visit. Okan and I have saved most of our sightseeing to do with Joy and Margaret so we will be visiting different parts of the country with them.

Busy
Much to my surprise we caught a genet yesterday. He was a youngster (1 yr old) and very, very cute. We met some men on the trail who asked us if they could kill the genet and eat him. It was very disconcerting. These are men who are hired by the park to keep the trails clear. We told them to beat it and luckily a park guard was nearby to keep them away from our furry friend.
We have had a very busy last few weeks. We deployed more camera traps in the middle of Nyungwe 2 days ago that resulted in an 8 hour day of hiking up and down mountains. Even Okan, who never gets tired (or so it seems), is ready for a break. We have now returned to Butare and I'm heading to Arusha for a conference tomorrow.
My friend Robin tooks some nice pics of us while we were baiting the traps the other day as well as some good pics of animals we saw along the way to deploy camera traps.
We were baiting with hard boiled eggs
I couldn't do all this work without Okan!
Everest the guard came with us that day.
Okan doesn't mind baiting, but he refuses to put out the lure (an oily smelly pungent liquid to attract animals to the trap. It takes FOREVER to get the smell off your hands!)
Baboons on the road

Dry Season has Started
I've finally started live trapping but am not catching any animals. In part, this is because the lovely folks who issue the research permits, forbade me to use live bait (chickens, which are protected in the trap by chicken wire so they are never harmed). I got the call about not using live bait literally as we were driving to the field site with four small chickens in our back seat (which took Okan hours to procure). While it might seem cruel to you to use live bait, it is really one of the best ways to capture carnivores in huge forests like Nyungwe because the chickens make noise that attracts the predators. I won't bore you with the reasons why they forbade me to use live bait, or why the decided to make this change as I was deploying the chickens, but it is extremely disappointing given that they approved my permit to do this in April and I have dotted every i and crossed every t with regard to working with the permit agency and my research. Anyway, don't expect any capture photos anytime soon.
The good news is that the camera trapping continues to yield great pics of carnivores and other animals (see below). The field work has been utterly exhausting. In the mornings this week, I have hiked for several hours with my students and have been training them in capturing small mammals. After a week, they are now on their own and doing well! But it has been exhausting because after getting back from the students, I eat a sandwich and then go out to hike my own trail and bait traps. We are hiking 10km a day every day. Okan however, doesn't feel this is challenging enough. So he hikes OUT to the trail from another trail which adds another 5km to his daily hike. Today he hiked up the trail where my traps are in only 30 minutes (it takes me closer to 1.5 hrs!). Needless to say, it is hard to keep up!
Okan is all better from his Giardia and while we are both exhausted from the field work, we are otherwise well and healthy. This weekend we have friends in town and will take them to my field site tomorrow in Nyungwe. Then next week I go to Arusha for a conference for a week.
Ok, some quick pictures of the animals I have found on my camera traps!

Giardia x2
The mystery of my massive weight loss seems to have been at least partially solved with my diagnosis of Giardia. Now unfortunately, it looks like Okan also has it and his host of symptoms are pretty unpleasant. But at least we know what it is and he has started medicine and is already feeling better just one day after starting the medicine.
We started in the field last week. After getting up to Kitabi we hired a bunch of porters who helped us deploy our traps up the mountain. It was a pretty big ordeal getting both the traps (huge) and many porters to the trail site. Once we got to the trail the porters were practically running up the mountain with their traps. I was following behind baiting the traps and putting them together and in good spots where they would be hidden. Okan and the porters made it up the 5km uphill trail in only an hour and a half, but it took me much longer to catch up and finally finish all the trap positioning etc. It didn't rain and it was a nice day so that was helpful. I am currently pre-baiting. This involves putting yummy treats into the trap, but the trap is wired open so the animal can come and go as they please. The idea is that they get used to the trap and the treats (raw or cooked eggs) and come back. We will hopefully be going "live" with the traps (ie taking out the wire that keeps them open and setting them for real on Monday.
Two of my students are also coming up with us. One is doing his memoir on the foraging ecology of the animals I capture, and the other is studying small mammal community dynamics. I find it really overwhelming to have them both up there while I am just starting my trapping. I want to spend more time training them and getting them set up but just getting my project up and running is a lot of time and energy. The hike up the trail from 2500-2800 m where my live traps are is 10km round trip and so when we are done, I hardly have any energy to go on another hike to help my students on their trails. But I am just going to have to bite the bullet and do it this week and hope they will get trained quickly so that I won't have to do field work from dawn to dusk every day. The work isn't so hard as the hiking. I pulled my achilles on the first day in Nyungwe this week and so you can imagine how fun it is to hike when your achilles hurts! Plus, I am still not used to the altitude and the very steep inclines. Okan can get to the top of the trail in 1 hour (even with Giardia!) and it takes me 1hr 30 minutes of panting to get to the top. Luckily, sometimes Okan can come back down and meet me as I am coming up to tell me if the traps need rebaiting or not. Or like on Thursday, I went on a hike with my student to find a good field site while Okan and another friend went and checked the traps on a different trail. Okan has been the best field partner in the world. I lost my phone one day in the field and thought it was gone for good, but Okan found it at trap #13 the following day.
Here are some baboons that frequent the road to our field site. We see troops with 50 individuals just meandering down the road. Some sit in the middle of the road and get groomed by another baboon as they enjoy the heat from the asphalt. Hopefully I will have more exciting photos to post sometime soon once live trapping begins!

False Start
We had a bit of a false start in the field last week. We started out by putting out lots of new camera traps on a rainy afternoon after we had moved all our equipment up to the field station from our old house in Butare. I wasn't feeling great all day and by the next morning had a nasty case of the flu. So we drove back to Butare and Okan nursed me back to health. Of course 2 days later just as I was feeling better, poor Okan caught the same flu and he has been pretty sick the last few days. We're both on the mend now but it put a crimp in our week. Hopefully back to the field this week!

Let the Field Work Commence!
We finally have started in the field. Our first five camera traps yielded lots of fun pictures (below). We have deployed many more cameras and now today we are actually making the move to Kitabi full time. We'll deploy more cameras today. Then tomorrow hike some trails to find suitable places to put my live traps on Wed. or Thursday.
The last two weeks has been exhausting. We have been to Kigali and Nyungwe and also trying to catch up on other work. Okan finally made the bike ride from Butare (where we live) up the many, many, many hills to Kitabi (edge of Nyungwe). It looks, from a non-cyclist perspective, like it would be a brutal bike ride as it's mostly up hill. But Okan enjoyed it and made it in 2.5 hours (it takes me 1 hr to drive!). He said that mostly people just stare but some of the kids run with him and try to grab onto him as he bikes by, which is dangerous and annoying. But otherwise he really enjoyed it. And then after the bike ride, we proceeded to hike the trails with 40lbs of camera equipment in each of our backpacks up the mountain for another 3.5- 4 hours. I was, like last time, huffing and puffing and really feeling the altitude. Since Okan had biked up to Nyungwe that morning, instead of skipping up the mountain like he usually does, he actually walked, albeit much faster than I. If only I could swim up the mountain! Hoping I will get used to the hike after a week of doing it every day. Really looking forward to capturing animals in the live traps soon. First a week of pre-baiting (where the trap won't actually capture any animals but they can enter it and get the bait and leave). Then I'll activate the traps for real. Keeping my fingers crossed! Still quite rainy here and hoping a quick end to the rainy season now that we are starting full time field work! Here are some of the first camera trap images we got from the first month of trapping with only 5 cameras. We are just finishing up deploying the other 15 today.
The first picture is of a genet and the second picture is of a duiker.
We saw a number of people on our camera traps, mostly farmers. Oddly, there are several frames of this woman burying some seeds and then hoeing the soil. Note this is near the summit of the mountain and probably takes close to 1.5 hrs to hike up so it's a little odd to see someone planting something along a trail!
This picture is of a side striped jackal. The main culprit for leaving all the scats I keep finding near this camera trap. I can't wait to trap him!
This is an over exposed picture of either the same jackal or a different jackal marking his territory right in front of my camera trap! Maybe he wants us to know HE owns this trail!
The first is a blurry photo of a chimpanzee! So excited to see them on this side of the forest and walking along the trail! The second picture is quite a large serval. Too bad the camera's trigger time appears too slow! But at least I know they are there. I can analyze the spot pattern on his fur to identify different individuals. In the picture below, first you see three tiny piglets. Then the next picture mama comes into the frame! It is a wild boar.
Another duiker
I like this picture of another side stripped jackal because he looks like he is hunting! The picture below is of a blue monkey
Well, that's all for now. We're off to Kitabi now!
