Teaching Models to Listen to Bats: The Story Behind BSG-BATS Post provided by Katarina Meramo Bats are extraordinary animals. They fly, echolocate, and navigate in absolute darkness, and produce some of the most complex acoustic signals in the mammalian worl…

Our Methods Blog post on BSG-BATS — a new fully open-source portal and ML classifier for bat calls — is out now! 🦇<3

Here's the story behind it, why open tools matter, and what comes next:

BSG‐BATS: An open‐source data annotation portal and classifier for European bat vocalizations Bats are ecologically important mammals whose monitoring increasingly relies on acoustic data. However, many tools for bat call identification remain subscription-based, closed-source, region-spec...

Our new paper on an open-source ML system for identifying European bat calls is now published in MEE! 🦇

With BSG-BATS, anyone can contribute, annotate, and run open-source models — making large-scale acoustic monitoring more accessible than ever.

Bat census 2025 at Salpalinja! 🦇❄️

Super cool & sunny weekend monitoring hibernating bats in the bunkers of Salpalinja. We checked more sites than ever — and found 424 bats! 78% of the bunkers had bats, with the badass northern bat dominating. Huge thanks to @nathist.bsky.social for organizing this!

Väitös: Sudet kuuluvat Suomen luontoon | Helsingin yliopisto Susiensuojelua ja luonnonsuojelua tulisi käsitellä poliittisesti osana laajempia yhteiskunnallisia rakenteita, todetaan väitöstutkimuksessa, jonka osana tehtiin ainutlaatuinen musiikkialbumi.

Usein sanotaan, että negatiiviset asenteet susia kohtaan olisivat automaattinen osa ihmisten ja susien yhteistä historiaa. Tuore väitöstutkimus esittää, että etenkin eliittiin kuuluneet metsästäjät loivat aktiivisesti negatiivista kuvaa susista 1900-luvun vaihteessa. www.helsinki.fi/fi/uutiset/h...

Fast vocal-motor tracking of escaping prey in echolocating bats - BMC Biology Background Echolocating bats face an intense arms race with insect prey that can detect bat calls and initiate evasive maneuvers. Their high closing speeds and short biosonar ranges leave bats with on...

Ever wondered how echolocating bats, despite their high flight speed, track escaping prey? Check out our latest publication in BMC Biology 🦇.

Eptesicus nilssonii

#Urbanization changes also our boreal landscapes—but how does it affect #bats? 🦇 Thrilled to share part of my PhD research that highlights the importance of old forests for bats and the challenges land-use changes create. Curious? Read it in Landscape Ecology: tinyurl.com/batsinboreal 🦇🌲<3

On this shortest, darkest day of the year, I’m throwing it back to a Nordic summer night with this amazing northern bat (Eptesicus nilssonii). Adapted to hunt under bright skies, these little legends never fail to amaze me! <3

Pipistrellus nathusii being its cute and secretive self :)

Hello BlueSky! I’m Kata, a postdoc fascinated by #bats and their ultrasonic world 🦇🌌 My research in the LIFEPLAN project focuses on decoding their calls to reveal hidden #biodiversity patterns and advance #conservation. Excited to share more about bats and what their #echolocation calls can reveal!
