From Frog Calls To Global Conservation: Scaling Citizen Science With AI
The Growing Challenge of Biodiversity Data Citizen science projects are generating more data than ever before. Global biodiversity databases now contain millions of species observations, creating an incredible resource for ecological research. While collecting the data is not a problem, researchers still need to analyze the sounds hidden within thousands or even millions of recordings.…

From What to Who? AI Learns to Recognize Individual Animals
Individual ID in Chatty Species In the wild, zebra finches don’t sing in isolation. They move through dynamic social groups, calling and responding to one another across space and time. For ecologists, understanding this communication requires knowing who is communicating with whom, and how information flows through a group. Tracking communication at the level of…

What Can a Primate Face Tell Us? A Scalable Approach to Studying Facial Expressions
Anyone who has spent time observing primates knows how expressive their faces can be. A lip-smack, a brief glance, or a subtle shift of the mouth can signal curiosity, tension, submission, or affiliation. For ethologists, these fleeting expressions offer a rich window into the social dynamics of a group. Studying them, however, has traditionally required…

Animal Language Processing: An AI Convergence In Animal Communication
We are starting to see the study of animal communication shift from narrowly defined, species-specific, and hypothesis-limited analyses toward data-driven discovery at scale. We refer to this convergence as Animal Language Processing (ALP), an approach that uses AI to study non-human communication at scale.

What Matters for Bioacoustic Encoding: A Practical Training Recipe for Building Generalizable Models
To better understand what matters for building a generalizable bioacoustic encoder, we tested 19 models across 26 datasets and a new evaluation benchmark. Our main finding is that a two-stage training approach—self-supervised pre-training followed by supervised post-training, both on a mix of bioacoustic and general audio—delivers the strongest performance.
