🦇🌙⛏ IT'S SPOOKY SEASON 🎃💀🕷

When you study #bioacoustics and #bats, there is always an appropriate Halloween outing!

This year, we went to the Mønsted limestone mine, a 60-km-long man-made cave system and THE place to be for winter hibernation (9000 bats surely can't be wrong!).

🦇CARNIVOROUS BAT RIVALS BIG CATS 🦁 IN HUNTING ABILITY

Researchers from our lab incl. Leonie Baier & @laurastidsholt.bsky.social discovered that the fringe-lipped bats of Panama hunt for prey near their own body size - similar to large cats!

Paper & incredible science alert: Our assistant professor @laurastidsholt.bsky.social & a passionate team @elena-tena.bsky.social @ebdonana.bsky.social found proof for greater nocturnal #bats 🦇 preying on migratory birds 🐦 AND devouring them in flight! #bioacoustics

Intense days for our PhD student @hejfabienne.bsky.social. In a joint effort @au.dk ,#ntnu PhD student @leayero.bsky.social & #UiB, have deployed 8 geophones + 2 soundtrap hydrophones along a #DAS enabled #fibercable in #Svalbard to compare #shipnoise measurements in an Arctic fjord 🚢🔊🐋 #seasounds

Successful day out in Aarhus Bay 🇩🇰⛴️ for our PhDs @cmarcolin.bsky.social @hejfabienne.bsky.social & MSc Matthias
⬇️deployed 8 hydrophone 🎧 stations with @innovasea.com releases and
⬆️recovered 2 after 9 months!
There #bioacoustics PhD project investigates #shippingnoise and impacts on porpoises 🐬.

🔊 Paper alert! 🐬🎧
Noise of high-speed vessels 🚤 impairs the #biosonar ability of #harbourporpoises 🐬 - making it more difficult for them to
🤯 sense surroundings,
🧭 navigate and
🐟 hunt prey
within several hundred meters.
🥳Huge contribution to understanding masking effects!

THIS IS HOW WE DO IT 🐬🎧- (when conducting #acousticmonitoring at #windfarms, e.g. for #Energinet in the #NorthSea)
- The equipment is deployed ⚓🎙️,
- then, stays out at sea for months🌊📆,
- then, we recover it using acoustic releases ⚓✨,
- and analyse it back home 🖥️🔊.

POV: Mia & Jakob successfully recovered an 🔊 acoustic array at a #WindFarm in the #NorthSea 🌊 - part of our #AcousticMonitoring work for #Energinet.
With the gear safely back, we can now look (& listen🎧🖥️) for #porpoise 🐬 vocalisations to learn more about how they move around the wind turbines.

Happy Monday. 😅
Some of us where out in the North Sea this weekend 🌊 #justhangingaround bioacousticians

Hej,
🔊🐋🦇we are the group behind Prof. Peter T. Madsen at the #Bioacoustics Lab @au.dk .

We eavesdrop 🎧🤫 on oceans 🌊 and night skies 🌙 - turning sound into science to understand & protect #marinemammals 🐬🦭 and #bats 🦇 🧛🏻‍♀️.

Join us for insights from the secret lives of #bioacousticians.
