Automated note annotation after bioacoustic classification: Unsupervised clustering of extracted acoustic features improves detection of a cryptic owl
Passive acoustic monitoring and machine learning are increasingly being used to survey threatened species. When automated detection models are applied…

Wasn’t expecting to see this on my walk yesterday - Noisy Pitta in suburban Brisbane!
They’re usually rainforest birds but migrate at this time of year and can show up in weird places.
Haven’t added any new species to my home patch list (now at 98) in ages, this will be hard to beat.

Birding is booming in Australia @birdlifeoz.bsky.social www.abc.net.au/news/2025-02...
How birdwatching is taking flight as Australia's new tourism goldmine
Birdwatchers are pouring billions of dollars into Australia's tourism industry every year with calls to capitalise on the country's native species and better promote the pastime.

Stoked to have a cover photo for @ecography.bsky.social! In our paper doi.org/10.1111/ecog... we included temporal dynamics into SSFs, resulting in daily patterns of movement and habitat selection.
Simulating gave us dynamic spatial predictions across the landscape.

Excited to present our latest paper where we take a close look at what we know (and are yet to know) about biodiversity in Antarctica!

First time birding in NZ. Cannot believe how many exotics there are everywhere. House sparrow chatter definitely most common noise of the day (Blackbird song close second).
Loved the Gannet colony!

Good morning, #ESAus2024! Lots of people joined the starter pack yesterday. Take a(nother) look for other austral ecologists to follow and check out the hashtag for interesting talks coming up today.

Hello Bioacousticians,
Turns out there wasn't a bioacoustics starter pack.
Just realised I myself am following the bare minimum number required to make a starter pack.
Please share & nominate yourself!
Hoping to see this pack grow.

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 it’s the first Eastern Bristlebird heard in QLD in 5+ years found using acoustic recorders + a deep learning model.
