Just finished up a big few weeks with four talks at three conferences. Thanks for having me #Acoustics2025, #AOC2025 and #ESA2025. So good to learn from so many brilliant people. Also managed to find some time to see some wild Numbats + a few other cool plants & animals. Now time for a nap 😴

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.
It's Qld Labor in Bonner. This is massive. This seat hasn't moved from Qld LNP since 2010. #ausvotes
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. Code! github.com/swforrest/dy...
Introducing Open Ecoacoustics: a platform for continental-scale ecological monitoring and research in Australia. As part of ARDC's Machine Observation Data Processing Infrastructure, we use ecoacoustic technologies to promote open science and conservation. #OpenScience #Ecoacoustics #bioacoustics

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! 🔗 Check out a summary of the work: arcsaef.com/story/new-an... 🔗 Read the paper here: doi.org/10.1111/ddi....
Are you a scientist that analyses/creates models using data from cameras, acoustics, drones or satellites to understand biodiversity? Join the Biodiversity Monitoring starter pack. Point me to your research to be added. ECRs and PhDs welcome! 🧪🌏 #AI #conservation go.bsky.app/eFMQQX

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!
@callanalexander.bsky.social on birds in vineyards - heaps of native birds present, and using a cool combination of supervised and unsupervised machine learning models to overcome false positive issues in AI detection of bird calls #ESAus2024
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. go.bsky.app/5YmZLNm
Excited for #ESAus2024 this week! I'm speaking about birds, wine & machine learning on Thursday afternoon.
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. go.bsky.app/2Qmjek6
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.
