Social Learning &
Vocal Communication Lab
In this lab, we study animal vocal communication and social learning. In particular, we investigate vocal ontogenetic processes, the underlying mechanisms of vocal learning, and the impact of the social environment on vocal development and learning. We study these topics in bats and hummingbirds.
Where the Work Happens
Studying vocal communication in the wild, in the Neotropics and Germany.
Behavioural Biologist.
Bioacoustician.
I am an Emmy Noether Group Leader at the Institute of Neuro- and Behavioural Biology at the University of Münster.
As a behavioural biologist, I specialize in bioacoustics and biolinguistics. My research focuses on (social) vocal communication, exploring how and why animals communicate and how complex vocal systems evolve. I am particularly interested in vocal ontogenetic processes and the proximate factors and ultimate causes of vocal learning.
Vocal learning is a key factor in human language and infant speech acquisition — hence, my research questions also forged my interest in biolinguistics: the study of the biological foundations of human language in non-human animals.
By integrating ethology, bioacoustics, neuroethology, and endocrinology, I take a multidisciplinary approach to studying vocal ontogeny and learning.
On September 1, 2025, I started my own Lab in Münster and am welcoming dedicated and curious students. Feel free to contact me.
From Babbling to Singing
Investigating vocal communication, ontogeny, and social learning across two extraordinary and contrasting systems: highly social vocal-learning mammals such as bats and largely solitary hummingbirds with extraordinary vocal capacities
Bats
The greater sac-winged bat (Saccopteryx bilineata) is one of the few mammals exhibiting vocal learning. Pups produce babbling behaviour strikingly similar to human infant babbling. My research investigates the ontogeny of their complex vocal repertoire, the role of maternal feedback, and the neural substrates of vocal production.
Hummingbirds
Hummingbirds are among the few avian lineages capable of vocal learning. I study the vocal communication and learning processes in Neotropical hummingbird species, exploring how high-pitched vocalizations are produced, learned, and used in social contexts across their natural habitats in Central America.

Wiebke Berns Has Joined the Lab!
Wiebke Berns is studying the social behaviour and acoustic communication of the fascinating Greater horseshoe bats. In June and July, she will dive into fieldwork in Bavaria, at the Fledermaushaus Hohenburg. I am so curious what she will be discovering and describing! Welcome Wiebke!
Mentoring-Programm ERSTKLASSIG!
I have been accepted into the mentoring program ERSTKLASSIG! offered by the University of Münster. “Erstklassig!” is an 18-month fellowship program aimed at outstanding postdocs, researchers preparing for their habilitation, those who have completed their habilitation, and assistant professors from all departments at the University of Münster, offering them targeted support on their path to a professorship.
The program aims to facilitate the exchange of experiences and expertise with experienced female professors (self-selected mentors), support individual career planning through mentoring and workshops, and prepare participants for research and leadership roles. It also promotes peer mentoring and networking among female researchers.
Tinbergen Award 2026
I have been awarded the prestigious Tinbergen Award 2026 of the Ethologische Gesellschaft e.V. It is an absolute honor to be included in the list of fantastic researchers who got the prize before me. I am invited to give a talk about my research before officially receiving the award at the ECBB.
Forschungspreis 2025 der Deutschen Wildtier Stiftung
A long-term research project is now possible: I was awarded the Forschungspreis der Deutschen Wildtier Stiftung and this allows me to investigate the social and vocal lives of the Greater and Lesser Horseshoe bats in Bavaria. So excited about this opportunity!

The German Wildlife Foundation is dedicated to giving a voice to native wildlife. Through its work, it helps raise awareness of the beauty and wonder of natural life and works to counteract the growing disconnect from nature.

Appointed Research Associate at STRI
I was appointed Research Associate at the renowned Smithsonian Tropical Research Institute (STRI). Having worked with STRI since 2015, it is an honor to now be officially affiliated with this amazing tropical research institution. I look forward to a fruitful and exciting collaboration.
Emmy Noether Grant Awarded
I am thrilled to announce that I have been awarded the prestigious Emmy Noether grant from the DFG. This funding will allow me to establish my own lab and continue investigating vocal learning and communication in bats.
Outreach & Media
I consider science communication to be an important task of a scientist in order to explain research results to the general public and promote interest in research and the conservation of nature. I enjoy doing outreach in different formats such as interviews, guided tours and lectures.
Meet the TeamUniversity of Münster
Our interdisciplinary team investigates the fascinating world of vocal learning and communication — from the molecular mechanisms of vocal production to the social dynamics of bat colonies in tropical forests.
Natalia Adamowska
Natalia Adamowska began researching the acoustic communication and social behaviour of maternity colonies of the Greater mouse-eared bat for her Bachelor's thesis. She patiently observed the bats and their social interactions in their day-roosts during pup development and recorded their vocalisations. For her master's project, Natalia is currently analysing a call produced mainly when bats were approaching or leaving a roost, and when young bats started to become flight-ready. She is investigating whether this so-called contact call carries a vocal signature that encodes information on social group membership.
Wiebke Berns
Bavaria currently hosts the only known maternity colony of the Greater Horseshoe Bat, Rhinolophus ferrumequinum. In her master’s thesis, Wiebke Berns combines behavioural observations with simultaneous acoustic recordings to investigate the species’ vocal communication and social behaviour.
Jimena Jara
Jimena Jara is currently involved in a project which aims to investigate speech-relevant gene expression (e.g. FoxP2) and immediate early genes (i.e. neural activity) in the vocal learning bat Saccopteryx bilineata. She is currently using free-floating in situ hybridisation to analyse a dataset including brain tissue from three contexts: learning, vocal production, and silence.
