Today was an exciting and rewarding day at Las Cuevas Research Station! We went back into the forest to retrieve the camera traps we set up when we first arrived on May 19. It felt great to collect the equipment after it had been silently observing the rainforest for days. These cameras are key to helping us understand more about the wildlife here—especially the birds that are often hard to spot in person.
We spent most of the day working on presentations. In the morning, we wrapped up our rainforest presentations and then began preparing for our upcoming reef topics. It was a great opportunity to reflect on what we’ve learned so far and to practice communicating that knowledge clearly. Talking about the incredible biodiversity here made me appreciate just how much we’ve seen already.
In the afternoon, we gathered as a class to look through the photos from the camera traps. It was so interesting to see what animals had wandered by while we were off doing other things. One clear trend stood out: cameras on the trails captured far more activity than those placed deeper in the forest. This made a lot of sense—animals, including birds, often use trails as pathways, just like we do. Watching these patterns emerge really brought our research to life.
Later that evening, we had dinner outside and were treated to something incredible: fifteen scarlet macaws and two parrots flew overhead while we were eating. It was an absolutely surreal moment. Seeing so many brilliant flashes of red and green cutting across the sky was breathtaking—definitely one of those memories I’ll never forget. We ended the day gathered around a campfire deep in the forest, sharing stories and soaking in the sounds of the jungle. It was the perfect ending to a busy, beautiful day.
Now that we’re all situated in our jungle abode, we are really able to maximize the rainforest surrounding us to do field work. After a peaceful wake-up, sipping coffee and watching birds on our cabin porch (we saw scarlet macaws and yellow-bellied flycatchers!), we spent the first half of our morning cooking up a research project in the lab for our week at Las Cuevas Research Station.
Dr. Solomon gave us these guidelines: We were given 14 motion-sensor cameras (one for each student) to place around the jungle to measure something. We decided to look at the impacts of human disturbance on biodiversity in the area, asking how the presence of man-made trails (hiking trails and roads) affects vertebrate diversity (mammals, birds, anything with a backbone). We would look at the number of species and the number of each individual within that species recorded by camera shots.

In our comfortably shaded cabin, our class gathered together around a giant map and pointed to ideal camera locations, totally underestimating the amount of steps and sweat that would go into actually setting these cams up. We decided to pair each “human disturbed” camera location on the trail with another “undisturbed” camera off-trail nearby, keeping both cameras within the same general vicinity for consistency. So we had 7 different general locations to hike to in order to install our 14 cameras. With project methodology in our heads and recorded in our little field notebooks, we slid on our boots and set out for the trails.
While hiking to placement locations, we turned over quite a few logs to reveal pretty cool (and tasty) treats. Did you know that termites taste like carrots? Genuinely just like carrots; if you ever have an infestation, just cook them up for a little protein snack…that tastes like carrots. It’s because they contain some carotenoid compounds like carrots, giving them a sweet, earthy flavor. Ooh, also! I need to add a few more pages to my epiphyte identification card. Vascular epiphytes (the ones with stems) are estimated to make up to 25% of all vascular plants in tropical rainforests (https://link.springer.com/chapter/10.1007/978-94-017-3606-0_5), and we saw a few more epiphytes than the 20 listed on my sheet today. We spotted this tiny bromeliad I need to run through Inaturalist to identify. (Update: I think it’s a Tillandsia schiedeana).

We were out all day scouting for ideal camera placement locations. This involved cutting through vegetation off the main trails to put cameras in “undisturbed” areas, 50 paces into the forest from each trail camera location. We recorded GPS coordinates for all camera locations and marked them with neon yellow tape for easy retrieval.
Because Dr. Solomon had a “professor-only” policy for using the machete, he was the only one slashing through the forest. By camera #11, we began to imagine Dr. Solomon as a video game character, from either a fruit-ninja/jungle-explorer game. We called out point values based on the satisfying-ness of his chops. A clean chop of a thick stem earned him 20 points, but a thin, easy chop would be something like +5.
There was one site off the trail that had particularly dense, unpassable vegetation, and as soon as my friend Sahana saw the thick green barrier in front of us, she exclaimed, “Wow, it’s giving undistributed.” We laughed and cheered Dr. Solomon on by shouting out points as he cut through.
This day was super tiring (we got our steps IN) but super funny. We found ways to joke about our work while stopping along the way to learn about species and their interactions. With a tan and new inside jokes, I feel content and excited to get back to the field tomorrow.
After sunset (pictured above), we had an opportunity to go out into the rainforest, and this was quite the adventure. As you would imagine the rainforest is foreign and unforgiving already in the daytime, but in the nighttime it takes up a different sort of personality—a more threatening one, and for the first time I felt slightly un-safe while cruising the trails. My general disregard for the danger of animals helps me feel safe in the jungle when the sun’s out, but at night even I started feeling hints of fear.
We saw many spiders and many crickets. The crickets were plentiful. I saw at least four that were large, maybe 5 cm, with long antennae often the size of their body. They were shiny and easy to spot in the dark. I also saw a surprisingly large amount of monkey grasshoppers, five in total. This is surprising since grasshoppers tend to be diurnal. I also saw katydid nymphs with very strange morphology, longer-limbed than their adult sizes, pictured to the right next to a monkey grasshopper picture.

Once again there was a moment of total darkness, as we all turned off our lights and stood in the rainforest. It was different from the cave—more alive. We stood in the darkness for a few minutes, and the stars shone above a lot brighter than they ever are in Houston, or anywhere else. We spent the rest of the night watching the stars off the staircase of the station, talking and listening to the sounds of the rainforest.
Today was the day I was looking forward to the least out of this whole trip, the day where we set up the camera traps. I had read some of the blogs from last year, and they said they hiked thirteen miles. Luckily, we did not go that far
We decided to use the camera traps to test whether there was differences in the abundances of big cats and of big cats’ prey on the trails versus in the forest. We did this by placing three traps on the 50 Hectare Trail and four on the Monkey Tail Trail. Also, for each camera we placed on the trail, we placed another one 300ft into the forest for a total of fourteen camera traps. Scott Solomon did not tell us until we set the last trap that no group had ever used that many before.

As we were finding our way out of the forest after setting the very last trap we got a little bit turned around, and dusk was just starting to fall. A large portion of the trek back to Las Cuevas was really dark. We saw a small tommygoff snake in the dark, which was a little spooky because I would have not noticed it had Damien not pointed it out, and it is the most dangerous snake in Belize.
Other things we saw on the hike were a Mexican Porcupine, Scorpion Eater Snake, Blue Morpho Butterflies, a mantis molt, a wheel bug, and a mammal skeleton. We also saw some cat scratch marks near where we set the traps, which seemed like a good sign.
A cool Wheel Bug we saw this morning.
I saw a few Orthoptera species today. One was the same Leaf Mimic Katydid that I’d already seen. The other hopped away too fast for me to identify it.
We are all tired and ridden with ticks from walking through the forest, so these traps best capture some really cool pictures. I want to see a tapir the most. Out of the cats, I’d like to see an ocelot the most, probably.
Today was the second to last travel day of our trip. We reached Las Cuevas and will stay here until the 30th when we’ll head back to the airport in Belize City.
The drive was mostly through the Pine Ridge Forest and the Chiquibul Rainforest. To break it up, we stopped in the Rio-On pools midmorning. This was for us to get an idea of the karstist geological features of Belize and to swim and enjoy ourselves.
At Rio-On, there were a lot of granite rocks with small pools and waterfalls between them. It was fun to scramble around on the rocks and try and slide down the waterfalls. We stayed there about twice as long as we were supposed to, but nobody seemed to mind.
Rio-On Springs. It was really fun to swim and climb around here.
When we got to Las Cuevas, we learned that the cave here is closed. The worst part of this is that we all brought caving helmets and we aren’t going to ever use them. At least we got to see the ATM cave already. We also learned that there isn’t Internet here, which is why all these posts are going to go up at once.
Shortly after arriving, we went on a short hike on a trail near the station. We saw ceiba, cedar, acacia, sapodilla, Gumbo-limbo, and prickly yellow trees. We also saw fish tail palms, a plant that is often illegally extracted by Guatemelons for the floral business.
I saw two species of Orthoptera, which surprised me. One I think was a species of Leaf-mimic katydid (Mimica spp.) The other one I couldn’t confidently identify yet but it might have been Amblytropidia trinitatis.
A Leaf-mimic Katydid.
Tomorrow we are forming a question that we are going to answer with camera traps, and we’re going to spend most of the day setting them up throughout the forest. I think it is going to involve a lot of walking, which I am not looking forward to because my foot still hurts from when I stepped on a conch.
We finished out the last day with another 13 mile hike to pick up all our camera traps. It took us about half the time it did on Thursday and I wasn’t nearly as tired. It’s amazing what your body can adjust to after just a few days. Even though I’m running on less sleep I feel great because of all the exercise and activity.
Checking the photos from camera traps was more exciting than you could possibly imagine. Most of it was nothing but when something popped up on screen we were elated. One of our cameras got a picture of a Tapir (!!!!) and another of an Ocelot (!!!!). Even though we only had a little taste of it I think I am starting to understand how difficult field work can be, but also how rewarding. I will miss the rainforest and all of its colors and scents and noises.
Even though we didn’t see many amphibians out here I didn’t feel too disappointed or bored because it meant I got to bounce around and look at everyone else’s taxonomic groups. The end of the dry season can be tough for herpetology but getting to watch birds, ants, mammals (I saw an agouti this morning), reptiles, and insects made up for it. Not to mention the plants! The diversity was incredible and I saw many more organisms than I was expecting.

Happy birthday Mom! You too Elena, sorry I missed them.
Well we all died physically today. I believe that the final amount of miles hiked was a little bit above 13. My feet are destroyed. The back of my right knee feels like a pulled a muscle in it. I have a bug bite with dried blood on it and a bruise. But I don’t consider today a bad day by any stretch of the imagination. Why? Because I spotted on the orchids on my taxonomic ID sheet. (Oncidium altissimum) It was so so exciting, I can’t even put it elegantly into words. These are the moments when it becomes painfully obvious that I have to be an EBIO. The major is all that I am interested in. Of course, I also saw the large green bromeliad (as well as a couple other structurally similar bromeliads), further reminding me to look for a book in LCRS. I think what my new strategy is going to be is to try to assess my findings via my pictures after the day is done. Especially on today’s hike, we were moving so quickly that I couldn’t figure out my epiphytes in time.
As for our project, we decided to look at how man-made clearings and natural clearings compare. We picked quite the variety of sites, which is why we ended up walking so far during the day. It took us so long that when we got back the station, it had been dark for hours, (I think we all thanked the EBIO gods when Scott said that tomorrow wouldn’t be nearly as much walking.)
Tomorrow we focus on ants, having just listened to the taxonomic briefing on the topic. We don’t yet know what the two projects will be but they will be great. I have no doubt that this will get me even more excited to take insect biology in the fall with Dr. Solomon.
