Acoustic Monitoring / Feed

Bioacoustic monitoring is one of our biggest and most active groups, with members collecting and analysing acoustic data from every type of wildlife, from birds and bats to big cats, and even reptiles!


Song Meter Micro experience?

Hi everyone, First off, what a great community this is! I only recently found out about it, and it seems like a game changer, especially for early career folk like me.I was...

Hi Lucy - my apologies ; I've only just seen your post.  Would suggest the SM configurator app too - looks good and I'm using it myself to estimate card / battery life combos for a long term monitoring project I will hopefully get up and running in the UK soon.  I haven't used a schedule such as yours but if it helps I've found SM Minis to generate file sizes of c. 5.5MB per minute (as 1 minute files) and I would imagine (but happy to be corrected) that Micros are sufficiently similar for that to be a reasonably accurate target figure.  However, I'm pretty sure I have come across references in texts which suggest the amount of energy and duration of signals recorded will also affect file size.  Someone more technical than me might be able to explain this more or know how this may be calculated for.  Hope that helps, Bob.

Our original tweet about this question is still getting replies! @baddiwad just jumped in to share her experiences in South Africa. I'm looking forward to our Inventory going live so all these can be captured in reviews on different hardware product pages!

Cleaning audiomoth circuit board

Hi everyone,unfortunatly I got quite a few audiomoth boards with different levels of water damage.I removed the battery holder and plan on cleaning the boards. Do you have any...

I'd also add that if the boards are just dirty or dusty, you can just remove all batteries, then wash with a toothbrush and water. Air dry (or use compressed air which speeds things up greatly) and then spot clean areas that need solvent with isopropanol as Harold mentioned. Also if you don't have access to conformal coating, you can also use a non-conductive clear lacquer.  The conformal coating covers all the components and prevents short circuits due to conductive water (ie: salt water) or other contaminants. However if you do use a conformal coating, make sure all cables are connected first and the device is in the exact state that it will be deployed in. Also don't conformal coat the battery connectors since you'll want to change out batteries periodically.

Hi Akiba, 
thanks for your this great advice! I used the conformal coating on parts
of the PCB with exposed metal but was has hesitent using it on the "backside" with 
 all the resistors and transistors. Also what about the "back" of the microfon. Might this side be coated?
Do you have any experience with coatings @alex_rogers

Commercially available connected audio sensors

Hi - can anyone advise if there is a commercially made passive audio recorder that can be powered by solar/battery and have 3g/4g connectivity - ideally with compression on the...

I am not aware of any such connected loggers/recorders but they would be nice. 

The AudioMoths have been revolutionary in providing audologging at a low cost but they take a lot of "data muling" (carrying SD cards in and out of the field sites) and swapping of batteries.



Hi Lars, thanks for the response. We are using lots of Song Meter Micro's atm and they have proved to be resilient. Just need something which doesn't involve going on site regularly - but get the data off. 

Rainforest Connection's (RFCx) Guardian devices may be of interest. They are solar-powered and have connectivity options for Wifi, GSM and satellite transfer. They've previously been used for detecting e.g., gunshots or chainsaws (using edge computing) and then sending positive detections/alerts to folks on the ground. RFCx also hosts Arbimon, a free, no-code software platform that facilitates analysis of audio data as well. Happy to chat more if you'd like to talk further about it!

Hydromoth settings

Hi Everyone,what is your #HydroMoth setup for freshwater ecoacoustic monitoring? What are your settings for...

Hi Robin,

Did you ever get any responses to your query?  Just recovered a hydromoth I was testing for MPA monitoring, but all the files have no audio on them.  Was curious what others were doing underwater.




Hi Jacob, 
you are the first one but I have been talking to other scientist 
about their projects. Right now we are recording and hopefully automatically detecting Eurasian otter (Lutra lutra) vocalisations.
Did you find out why your files were empty or was the sound level just too low?

Greetings from Austria,

Potential collaboration: integrating acoustics and NASA airborne remote sensing to monitor animal and habitat biodiversity

Hi everyone. I’m looking for an ecologist/ornithologist with experience in bioacoustics to collaborate on a project integrating on-the-ground acoustics with synchronous NASA...

Although not a professor, I know a fair number through long-term association with, and personally am using Audiomoths in collaboration with the UC System at the Blue Oak Reserve. 

I've developed a fair bit of scripts to automatically crunch things using 'Birdnet', as per: 

I can certainly facilitate dialogue with the Cornell Ornithology lab if you do not have those connections already.  

My own background is in remote sensing (SAR, etc) and currently working in machine learning (albeit for health care currently..) this project sounds fascinating!

Are you already working with Audubon, and/or people in the UC System?

I'll also note that I'm planning to work with a few parks in the DRC/Congo basin to deploy Audiomoths alongside their camera traps. 

Dear Antonio,

It is a long-shot, but this may be relevant to what you are looking for? I have collected across 4 seasons (2022) 8-10 days/season acoustic data from 11 stations located at pine forests of different post-fire regeneration stage (>20 years since last burn, burnt in 2001, 2009, 2018) in Greece. These are typical Mediterranean forest pine landscapes - but certainly not in California or South Africa. We did not have plans at present to continue collecting data - since we got all seasons of one year, but may be the existing data or future data from these or similar areas here in Greece would be relevant to what you wish to accomplish with the airborne measurements?

Feel free to drop me a line.

All the best,
