Our team is dedicated to the study of vocal communication processes of animals in their natural environment. We use a multi-disciplinary approach :
- Signal processing and Big data analysis (sound analysis & synthesis software, noise extraction methods, localisation, Machine learning,…)
- Animal behavior and Cognition (use of acoustic/visual/olfactory lures to decipher recognition mechanisms, operant conditioning, multi-sensor tag attached to animals)
- Imaging methods (MRI, Synchroton X-Ray)
- Biological analysis (DNA, biochemical analyses such as GC-MS).
Our team belongs to the Department of Cognitive Neurosciences at the Paris-Saclay Institute of Neurosciences.
What’s New ?

Fieldwork in Madagascar tagging humpback whales with our long-term collaborator CETAMA. We did some very cool playback experiments with Charlotte Curé and Loanne Pichot !!
Congratulations to Olivier and Andréa for their publications in Acoustiques et Techniques, issue 98, 2023 (only in French).

Isabelle and Mathilde spent one month in Namibia to study mother-pup vocal communication and finalise some studies for Mathilde’s PhD thesis ! Last fieldwork season for Mathilde… Again, many playback experiments done, and we got lucky by sighting several times a brown hyena during our early morning trip to the colony at Pelican Point.
A new video on our Youtube Channel ! The work done by Maevatiana during the 2022 breeding season of Humpback whales in Madagascar, 12 CATS cam deployments on calves ! Well done Maeve and Cetamada !
The team is out !! Fieldwork in Madagascar for Maevatiana and Olivier, studying mother-calf social interactions in Humpback whales, but also fieldwork in Australia for Isabelle doing some audio recordings of Australian sea lions at Seal Bay Conservation Park on Kangaroo island.

A documentary (15 min, in French only) has been done by Emma Fourreau, a student from IFFCAM (Institut Francophone de formation au cinema animalier de Ménigoute), on our research on the European Robin. Our guest stars: Fanny Rybak and Thierry Aubin.
Andréa, Chloé and Thierry in Cape Town to do some fieldwork on African penguins and communication at sea, acoustic recordings and lots of playback tests done, more results coming soon, stay tunes !
Nov 2021 – January 2022
Mathilde and Isabelle were doing some fieldwork in Namibia to study mother-pup vocal recognition, as well as neighbour vocal recognition in territorial males.
On July 22, Fanny has been invited to the Quai Branly museum to talk about the wildlife sounds (in French only).
Andréa just came back from her first fieldwork session on the AFNAP project. Check out the project’s webpage for some news!
Two book chapters from Isabelle published in the new book « Ethology and Behavioural Ecology of Otariids and the Odobenid » edited by Claudio Campagna and Rob Harcourt.
A great book, with everything you need to know about otariids and walrus 🙂
New paper on vocal production in two subantarctic seabirds published in Behavioural Ecology. https://doi.org/10.1093/beheco/arab020.
Congratulations to Charlène Gemard, another paper from her PhD work.
A new paper on olfaction abilities in California Sea lions published in Physiology and Behaviour. https://doi.org/10.1016/j.physbeh.2021.113408
Congratulations to Jules Brochon, our former Master student !
Fanny published a paper in French on the website « Planet Vie » on how and why do birds sing ? »
After nearly 13 months without any fieldwork, Mathilde and Isa are back to South Africa to investigate the vocal communication of Cape fur seals ! A real taste of freedom…
Welcome to Dr. Andréa Thiebault ! Andréa is joining our team for the next two years and she has been awarded a prestigious Marie Sklodowska-Curie European Fellowship for a project on African penguins. You can follow some updates on the AFNAP project here.
A new website for a collaborative project on the reduction of avian mortality in windfarms (« Réduction de la Mortalité Aviaire dans les Parcs Éoliens en exploitation » -MAPE ). In French only. https://mape.cnrs.fr/
Our team will investigate the best methods (acoustic and/or visual) to deter birds from windfarms.
A video clip produced by the CNRS on our research on Humpback whales ! (in French only)
