Incredibly grateful to have been awarded a research grant by @leakeyfoundation.org to support my research on vocal behavior in white-faced capuchins!

🚨 New paper alert! "Honestly exaggerated: howler monkey roars are reliable signals of body size and behaviourally relevant to listeners" www.sciencedirect.com/science/arti... We show that formants advertise body size and mediate social interactions in black and gold howler monkeys.

Kenai is one of few males still alive since I first arrived in 2021. While capuchins can live into their 30s, a long climb up the social hierarchy, followed by a violent deposition, has left its marks on this 17 year old abuelo. These days, he spends his time on the periphery, avoiding the drama.

One of the most common questions I’m asked: how do we find monkeys in the middle of the forest. The ‘put to bed’ is the most energetically conservative strategy but requires a very early alarm clock

Can white-faced capuchins discern dominance status through vocalizations? 📣🐒 This season, I’m running a playback experiment using lost calls from dominant and subordinate males to test whether listeners respond differently and can infer social rank solely from vocalizations.

Field season is underway in the tropical dry forest of Parque Nacional Santa Rosa in NW Costa Rica. I am conducting my dissertation research on vocal communication in white-faced capuchin monkeys! Follow along for fieldwork moments and cute monkey photos.

Excited to share our methods preprint on CapuchinAI! 🐒💻 We built a field touchscreen + real-time facial recognition system (YOLOv7) that lets wild capuchins “log in” and complete individualized cognitive tasks. @emoryuniversity.bsky.social @gatechengineers.bsky.social #PrimateCognition #AI

So fun to present my research to two classes of @tulaneu.bsky.social students about my journey into primatology and my current research using thermal camera to understand stress in great apes 📸🐵 Thank you so much to my dear friend @nickchapoy.bsky.social for inviting me!

Our new paper, led by Nicolas Chapoy and Kathy Jack, shows capuchin alpha males have wider faces and bigger balls. Read on for discussion of trait variation with respect to pre- and post- mating competition! Was a large effort by a great team 😍😎🎉 royalsocietypublishing.org/doi/epdf/10....

Evidence is increasingly showing how ethanol is naturally present in sugary food.

Ran into our old friend Greg while searching for monkeys- it’s good to be home in Santa Rosa! 🐒🌳 I’ve also had a less welcomed reunion with the local chiggers. Any pro tips to stop the itching? 🙏🏼 #fieldwork

Hello BlueSky! I’m so excited to join this growing community of ethologists! I’m a PhD candidate at Tulane, studying vocal communication and dominance in white-faced capuchins. I’m off to the field next week, but for now, a cautious encounter between a capuchin and Mexican hairy dwarf porcupine.

I'm still adding as I find more primatology peeps! Here is what I have so far!

Still buzzing from the white-faced capuchin conference in Santa Rosa a few weeks back! It was truly inspiring to hear about the history, ongoing research, and future directions of this amazing field site. KJack lab all in one place!
