Very exited about this! To start with we are looking to find and label some of their vocalizations to build a vocabulary, and to link them to video events.

Many very interesting audio-visual modelling challenges! I would like to build an audio-visual vocabulary to help understand their behaviour.

Sounds great! If you have a link to the PhD please send it. I'd be happy to have a look :)

Happy to! Are you studying auk acoustics as part of your post-doc, or what is your relationship to these birds? :)

The webpage is under development. Hopfully the playable Guillemot icons will have diffetent sounds soon that we collect during the season.

Auklab Audio Research News and updates about the continuous acoustic monitoring at the Auk Lab

Small webpage for an ongoing #bioacoustic monitoring project I am part of at Stora Karlsรถ: auklab-audio.github.io

Adding #audio will hopefully let us learn more about the life of the Guillemots. What are they saying?

Lesson learned: designing a recording setup is a challenge and lots of fun! ๐Ÿ”Š

Big thanks to all speakers and participants who joined the first Nordic Workshop on AI for Climate Change in Gothenburg, a great success! ๐ŸŒ๐Ÿ’ก

Next yearโ€™s workshop is already set: June 26, 2026 in Copenhagen ๐Ÿ‡ฉ๐Ÿ‡ฐ, hosted by our core team at KU & the Pioneer Centre for AI.

Let's keep up the momentum! โšก๏ธ

Noise pollution isnโ€™t just an inconvenience! ๐Ÿ”‰๐Ÿฌ
it can disturb entire marine ecosystems.

Understanding how noise disturbance affects wildlife populations requires powerful models, lots of data and a dedicated team.

For years I've had a long-term personal goal to have a project in my work that requires me to do fieldwork. Early this year I achieved that goal. And this weekend I will go to Stora Karlsรถ and install microphones in a Guillemot colony with my collegues @mogren.ml @delialia.bsky.social. ๐Ÿง

Part of micing up a Guillemot colony in the Baltic Sea (www.balticseabird.com/auklab/).

Switches with ethernet and power within 5 meters of all mics. Dynamic range important.

Any tips on hardware (e.g multi channel ADC rack and mics, IP audio) and things to consider are welcome! #bioacoustics

Thank you for writing this book. I study machine listening methods for bioacoustics. Books like this help me understand the variety of animal sounds, which lead to development of more useful methods. And reading about sound and animals is always enjoyable. Look forward to reading it!

BioacousTalks: Small Bird, Big Data, Deep Learnings with Nilo Recalde
YouTube video by K. Lisa Yang Center for Conservation Bioacoustics BioacousTalks: Small Bird, Big Data, Deep Learnings with Nilo Recalde

Just remembered that Nilo Recalde had an excellent talk about annotation/validation of thousands of audio clips at BioacousTalks: www.youtube.com/watch?v=n0fr..., maybe his software "pykanto" is worth looking at: nilomr.github.io#software. Depends on how much programming you are willing to do!

Yeah, I agree that it is not really built for large annotation projects in that sense. If you find what you are looking for, please write what you find in this thread! I'm also curious ๐Ÿ˜Š

Might be worth looking into Santiago's work: github.com/mbsantiago/w..., otherwise Raven Lite/Pro is nice. Not sure if it has all the features you are asking for.

Finally joined BlueSky!

I'm a PhD candidate mostly working on #bioacoustics, #machinelearning & #conservation.

This black squiggle (a spectrogram) may not seem like much, but itโ€™s the first Eastern Bristlebird heard in QLD in 5+ years found using acoustic recorders + a deep learning model.

I've just launched my new webpage, johnmartinsson.org, where I share my research on machine listening for bioacoustics and ecosystem monitoring. Especially happy about the little clickable animal icons in the top. Click on a few to make a soundscape! #Bioacoustics #MachineLearning #MachineListening

Counting individuals is a hard problem, and still an open research question. What is needed is a model of vocalization frequency for each species, to turn a pure species vocalization count into a count of individuals. Or a model that actually distinguish individuals (not aware of any currently).

Sounds very interesting! Do you know which species to expect beforehand? I would say that creating a spectrogram that shows some species should be rather feasible. Especially birds using e.g. BirdNET or BirdAVES, and some programming to process predictions and visualize results.

Hi! Thanks for reaching out. Sounds like a fun project. What are you aiming to detect in the gardens?
