Let's Support Bats


At Barbastella Echology, we focus on helping you understanding the dark art of bat sound analysis.

Bat sound analysis

We can provide support for your bat sound analysis work, from recording to processing and identification. Whatever the goal is, from ecological impact assessments to research papers, we can tailor our approach accordingly. We offer sound analysis services globally.



We can train you and your team to improve your bat sound analysis skills. We also offer regular courses on various related topics. Nils' experience with bat acoustics from all continents gives him a unique perspective on how to learn about this 'dark art'. Get in touch to have a chat about your training needs.



Inspired by the Big Bat Year, a world tour in 2019 when Nils set a world record of 400 bat species seen in one year, Barbastella Echology continues to undertake research all around the world with ongoing projects in Peru, Western Asia and Seychelles with many more to come in the future.

What's new from Barbastella Echology?

At Barbastella Echology, we are never idle. We've analysed tens of thousands of sequences for various clients, in Europe and beyond.
We've also been developing a brand new course focusing Myotis species, aiming to be the most in-depth training course for this group. This course will be coming in December 2022.
Finally, we are expanding our horizons by organising a conference to Audiomoth and all the different taxa that can be studied with this open source acoustic recorder. Tickets are available now.


Professor Charles Hood

Nils combines an encyclopedic knowledge of bats and their ecology with professionalism and a powerful work ethic. He not only helped me out with material from Oman and the United Arab Emirates, but he made me eager to collaborate with him in the future.


Anna-Lena Hendel (Uni Freiburg)

During the intensive course on bat bioacoustics with Nils Bouillard at our university, we particularly liked the mix of input sessions and live demonstrations of bat recording analysis. The course helped us a lot in gaining confidence and identifying bat species more efficiently. Despite the different levels of experience and backgrounds we brought with us, he managed to pick us up and have fun going through and
discussing numerous example recordings.


Patrice Dubus

The experience and passion Nils shares is a really invaluable addition, as it provides practical ways to ensure you get optimal recordings whatever your equipment is, and to assess which information can lead to a specific identification with many examples.
Recognising the limitations of recordings in some cases, which would lead to a broader, but more reliable identification is also a proof of the value of what Nils teaches.
