I have to apologize for my last post. It seems that the lovely article I slaved over (ok I wrote it in 30, edited it in 20) previously published without any text. I truly don’t know what happened. When the post linked to my Facebook and my LinkedIn, the text showed up. But then, when you clicked on the link to read more, the text was gone. The only thing that you, my devoted readers, would have discovered was a headline entitled “What I Eat and Other Things” with a comically large picture of a cup of coffee and a carton of Leche Mú! milk. That, my friends, was up for a week and got 9 whole views. So there are 9 whole people out there who potentially think all I consume is coffee and Leche Mú! milk. So disclaimer: I do not just consume coffee and Leche Mú! milk (although I do drink a lot of coffee – it’s Costa Rica after all. That, and half the week I wake up at 4am).
So recap of lessons learned: 1) Double check your WordPress posts a day or two after publishing, and 2) save all posts to your computer. These are the kind of “important life lessons” I am learning on this adventure. But, I digress. The main point of my last post was the lack of fun new adventures I had to share. The main point of this post is my abundance of fun new adventures to share. The following is one of them.
How I ended up in the Middle of an IGE
Picture this: I am on the ground sitting cross-legged on a paved road. I have a stick in one hand and a small test tube of monkey poop in the other. In front of me are several male Capuchins who have just burst out of the forest and are screaming and baring their teeth while running at full speed in my direction. Cue *record scratch* “Yep, that’s me, you’re probably wondering how I got here” freeze frame.
It was our first full day with Admin and I was on the wake-up shift. Luckily, Admin stays close to the administration area of the park (hence their name), so I only had to leave at 5:30am to meet them just before the sun came up at 6. By sunrise, we were on the move toward La Casona, the famous monument here at the park. By 8am, Gill (the PhD student I am working with) and Susannah (one of the other field assistants) had joined me for the day. As it was our first day with this group, our first priority was to collect fecal samples from all the female monkeys. If you want to know more about why we do this, check out Gill’s website for a detailed description of her project. But for now, I’ll sum up our need simply as “hormone collection”.
The nice thing about hormone collection is that once we have collected one round of fecal samples from all the females within a group, we are done with collection until the next time we rejoin them 1-2 weeks later. The catch is that fecal sample collection must be done before noon. By 9:30am on the day of my story, we had collected none.
Now you might be wondering, “how does one go about collecting a fecal sample?”. Glad you asked. The researcher must choose a particular monkey to follow around until it poops. Once you see your monkey poop, you must never ever ever take your eyes off said poop. You must watch said poop fall to the ground and stare at said spot on the ground as you walk toward said spot to collect said poop. Once you have located said poop, you take a nearby clean stick and use it to transfer said poop into a test tube. Once you have done this and written the proper identifying information on the test tube, your ordinary said poop has now become an “important fecal sample”. This “important fecal sample” must be immediately put on ice in your cooler (that the researcher carries around without complaint, despite its clunky, dumb, obnoxious, annoying added weight). Once your fecal sample is on ice, you start the process all over again. Sometimes, we have all our samples collected within an hour and it’s great, but on the day of my story, this was not one of those times.
Gill, Susannah, and myself had been following individual monkeys for about an hour with nothing to show for it. I was following a monkey named Beauty (who, incidentally, is not very beautiful). But after an hour of chasing her over underbrush and a rocky hillside, she did a beautiful/merciful thing. Beauty jumped to a tree right next to the road, sat on a low hanging branch, and pooped right on the pavement. I didn’t even have to go hunting in the underbrush! I could sit comfortably on the road and collect it right there! Considering the most recent sample I collected was in the middle of an acacia ant nest, I fondly think back on how easy this collection scenario was. These are the things I think about now.
Elated that I finally had the first collection of the day, I sat cross-legged in the middle of the road to quickly collect the sample and put it on ice. As I am doing this, we hear the sound of a screaming monkey in the distance. Then another. And another. These are the sounds of what we call an IGE, aka, an “inter-group encounter”.
An inter-group encounter is when one social group of monkeys fight another social group for disputed resources. This usually happens in overlapping territorial areas or over water, fruit trees, etc. On this day, the disputed territory was La Casona, and by the sounds coming from the forest, Admin wasn’t doing so great.
A few things happen when an IGE occurs. Most of the male monkeys stay and fight (although we have one badass female who usually participates) while the females and babies run the opposite way. This is rough because you, as the researcher, must run with the babies and females so as not to lose the group. As the monkeys started moving, Gill began shouting directions, “Susannah go with the females, I’ll record the data for the IGE, and Audrey just keep collecting that sample.” and they were off. So while all of this is occurring around me, I am still on the ground collecting poop.
Suddenly, the foliage in front of me is alive with movement and screaming monkeys. A few seconds later, the Admin alpha and the other males burst out of the forest and are running straight in my direction. We clearly lost, and they were retreating. I had to pull my arms in while they rushed past me, two swerving and just barely missing my exposed limbs. Following right behind was another habituated group called LV, and they were pissed. Teeth baring and shrieking, they stopped mere feet in front of me, while the Admin males sat behind me, turning my wide-eyed, cross-legged figure into a human shield. While they showed their teeth and barked at one another, I found myself stuck at ground level in the middle of their IGE, and unsure of what to do. Finally, LV retreated, and our males ran off into the woods behind me, leaving me once again alone in the middle of the road (and still trying to collect the poop). And that, my friends is the story of how I ended up in the middle of an IGE.
Both Gill and Susannah agree that getting to witness an IGE right at their level never happens, and I had a very lucky, cool, and unique experience. Our monkeys are comfortable with us and get very close on a daily basis, but I doubt I will ever experience the rush of fur grazing my arms from wild monkeys quite like that ever again. They asked if I was scared at all, and honestly the answer is no. The only thing I remember thinking was “damn I wish I had a good camera”. Oh and in case you were still on the edge of your seat about this: I did end up successfully collecting that poop.
