Todd with a Santa Rosa delicacy, squirrel tartare. Capuchins primarily eat fruit/seeds/insects but they are true omnivores. When the opportunity arises they will absolutely hunt bigger prey such as birds, lizards and mammals like this variegated squirrel
Chimpanzees have culture. Do they also have cultural heritage worthy of protection? @simonfitzpatrick.bsky.social and I argue they do in our new paper, because their cultural practices create value.

Itβs not uncommon for capuchins to babysit one anotherβs infants, but Kraken has taken it to another level. For weeks heβs carried Frodo almost nonstop. Even during fights he sets him down, then scoops him back up. As alpha, thereβs about a 90% chance Frodo is his. See the resemblance?

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

π¨ 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 Iβm asked: how do we find monkeys in the middle of the forest. The βput to bedβ is the most energetically conservative strategy but requires a very early alarm clock
Can white-faced capuchins discern dominance status through vocalizations? π£π
This season, Iβm 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! ππ»
We built a field touchscreen + real-time facial recognition system (YOLOv7) that lets wild capuchins βlog inβ and complete individualized cognitive tasks.

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 πΈπ΅ Thank you so much to my dear friend @nickchapoy.bsky.social for inviting me!
Thank you for joining us and sharing your research!! The students were fascinated!
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 πππ

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