Acoustic sensors enable efficient and non-invasive monitoring of a wide range of species, including many that are difficult to monitor in other ways. Although they were initially limited in application scope largely due to cost and hardware constraints, the development of low-cost, open-source models like the Audiomoth in recent years has increased access immensely and opened up new avenues of research. For example, some teams are using them to identify illicit human activities through the detection of associated sounds, like gunshots, vehicles, or chainsaws (e.g. OpenEars).
With this relatively novel dimension of wildlife monitoring rapidly advancing in both marine and terrestrial systems, it is crucial that we identify and share information about the utility and constraints of these sensors to inform efforts. A recent study identified advancements in hardware and machine learning applications, as well as early development of acoustic biodiversity indicators, as factors facilitating progress in the field. In terms of limitations, the authors highlight insufficient reference sound libraries, a lack of open-source audio processing tools, and a need for standardization of survey and analysis protocols. They also stress the importance of collaboration in moving forward, which is precisely what this group will aim to facilitate.

Hola Vanessa,
Aside from whats already commented, did you find any interesting new leads on this? I'm also interested in ways ecoacoustic tech can be used against wildlife crime, both as in research development, but even more so in its short or long-term applications and how it can be truly adopted in source countries.
It seems to me research or work in this is still limited but there's potential! I'd love to stay in touch about it :)
31 December 2024 8:02am
Hey Xiona,
I see that you are from a university that is very close to where I live. I have a platform that is well suited for combating wildlife crime and I perceive that it’s rather a small step to go from where I am to where you guys are all asking for. I suspect the piece I’m missing could be generated pretty easily with AI.
Would you be interested in having a chat about this ? Perhaps we can embark on a project ?

Camera trap triggered by loud noise coming from inside a nest box
28 December 2024 6:31pm
29 December 2024 6:18pm
Well, I have an audio recording project (https://github.com/hcfman/sbts-aru), that records potentially with highly accurate clock if you want to do sound localization, but you can use it to both record sounds and process an audio pipeline at the same time. And I have an AI object detector and video alerting project that handles input and output I/O as well. But it has a flexible state machine build in. It doesn't have to trigger with video, it's trivial to make it trigger from anything else. Such as the audio reaching a certain level, or even an audio pipeline recognising a certain sound. It's just a rest http call to the state machine, then it can capture video frames, with pre-capture if needed as well.
It draws a lot of power though. But I haven't tested the power usage when not running with anb object detector though. The lowest power Pi it can run on is a Raspberry Pi 4.
I have intentions to combine the two of these projects at some point to make something that can trigger on both object detection and also audio detection. When I get time... which is the only barrier. Bit it's not my highest prio right now.
It would definately need solar panels though to make it run for a long time. But in principle it would likely not be very hard to tweak it to trigger on sound. If this becomes a really must have bit of functionality, you could reach out to me directly. But it might be a couple of months before I could put any time into something like this.
I know that various people are interested in things like detecting chainsaw sounds. This could do that sort of thing with the right pipeline, but I haven't even started to play with audio analysis pipelines yet.
30 December 2024 3:42pm
That's great, we are in no hurry since this would be for next year's reproduction season. We would also be interested in the Ai that you mention if it's able to detect big size birds (working with the southern ground hornbill). That way the camera would trigger whenever the parents enter the nestbox. I asked a little bit and solar panels shouldn't be an issue. But to explain it in a more detailed way (exactly what will be need it, which camereas can be paired with the program, anything else relevant, etc) maybe we could keep the conversation through email: quimagell@hotmail.com
Im trying to explain everything to my bosses and would be great to know exactly what will be needed besaides solar panels and the camera (since this kind of technology is really new we might need some clear instructions and guidance, my knowlodge extens to CT and solar panels to power survillance cameras at nests but that would be it..). Thanks so much before hand!

Birdweather Puc use as a passive sensor
13 December 2024 6:46am
13 December 2024 3:07pm
Checking the Birdweather FAQ, I guess you need to be more detailed on the setup description. For example, if you use a powerbank to power the PUC that is NOT ALWAYS-ON, it may swich-off after some time. So details of your setup may matter.
Caveat, I do not have a PUC, but tried to understand you problem.
18 December 2024 1:03pm
Thanks for the advice Wade!
It will be great to hear Tim's feedback, but thanks for your advice! I think Lithium batteries are the next step for us. I have successfully gotten it working with a power bank attached, but that really impedes its portability. Will also fiddle around with the GPS per your recommendations...
18 December 2024 1:10pm
Hello Walter
Thanks for your input. I have achieved better results with the puc when hooking it up to a powerbank. Have got them set up to "recording only", and GPS to low power mode. Looking to now try eliminating the need for a power bank as that impairs the portability of the puc.

Insect call library
6 December 2024 8:28pm
6 December 2024 11:53pm
Hi Iqbal,
Xeno-canto has expanded the taxonomic scope and now has some insect calls there. There are a few insect-focused libraries listed on this compilation of bioacoustic reference libraries too. I believe there are aquatic invertebrates being added to the Freshwater Sounds Archive as well (led by @JackGreenhalgh). Ed Baker from NHM would be a good person to talk to - he's done a ton of work on insect bioacoustics.
Hope that helps a bit!
-Carly
9 December 2024 3:39pm
Hi Carly,
I've found and made use of Xeno-canto's libraries in the past, but for the current project plan to actually build a library myself. Thanks for the pointer to Ed Baker, I'll definitely follow up on it.
Cheers,
Iqbal
13 December 2024 1:36pm
Hi Iqbal,
I'm sure you could get some good feedback on this from XC users on this, particularly on the subject of protocols, recording settings, etc. So maybe a nice idea to post it on the forum there.
cheers,

New model for Europe - AvesEcho
15 November 2024 8:02am
18 November 2024 5:48am
My first test with known samples resulted in mixed results.
No one else looking into the model?
Greetings,
Robin
26 November 2024 1:01pm
It's still a bit early days. For nocturnal flight calls (which are the majority of the mysteries) the recordings are generally of poor quality and the model doesn't find anything (according to the tresholds we have set). We are running the model in the background on focal recordings from Europe as well, and there performance is pretty good. As we are not runnign BirdNET alongside AvesEcho, I cannot say at this stage which one is better, but my expectation is that AvesEcho should be an improvement, as it is based on BirdNET and is then further trained with more focal recordings. But time will tell if that is indeed the case!

Thanks, Troy! Makes sense. Average winter lows where we'll be deploying are right around freezing-- perhaps a few days that dip into the 20*F range, but not many. Definitely colder than is ideal for alkalines... but maybe Energizer Ultimate Lithium AAs would get them through?
My collaborators are hoping to monitor through the cold season for multiple years, so if they end up purchasing new units for this project specifically, I will steer them towards OwlSense units! We've been super happy with them at IBP.
19 November 2024 5:30pm
Very helpful; thank you, Akiba!
21 November 2024 4:12pm
I think lithium AAs would be ideal, but since it's not likely to be super cold I think you could get away with Alkaline if you're ok with somewhat reduced runtimes.

Owl Sense Audio Recorders
16 November 2024 5:32pm
18 November 2024 8:09pm
Nice to see you mention the primo EM172 mic capsules. Those are the ones that I use with my pi based recorder. They are the gold standard I think. But no mems microphone is going to be able to reach that same quality I think. At least none that I’ve seen.
Sounds like your made a mighty fine product.
19 November 2024 3:00am
Thanks Kim. Primo makes some good microphones and undeniably they are going to be better than any MEMS microphone. I do think folks underestimate what MEMS can do these days. Infineon really did some remarkable work with their IM73D122 microphone. It's significantly better than what's in an AudioMoth and even though its rated at the same SNR of a WA Micro, it subjectively sounds much better to me and others I've talked to. I'm excited to see what Infineon launches next, they've been leading the way with MEMS mics the last few years. Fortunately, Owl Sense is designed with a separate microphone board with the goal of offering better user-replaceable microphones when they are available!
19 November 2024 6:21am
The figures come very close to the primo mic. When I looked into this a couple of years ago I don’t recall seeing one come this close.
