Your HydroMoth experience!

Hi everyone,we just got our first dedicated #hydromoth in the post box. Anyone else about to start their bioacoustic journey? I would love to share our experiences, settings and...

Vinegar is also a great solution! Let it sit overnight and then just scrub it off. As a warning if you don't clean it, your sensitivity does decrease. You might actually see this if you keep it out there for a month that the amplitude of your calls decrease over the month/you might detect fewer calls. 

Hey! I would recommend a few things:

1) set up at least two in the same site kind of back to back or side to side if you have that many. Directionality can influence the number of calls you get and it's just good to know your error rate. 

2) Experiment with breaks and recording duration. You wont collect anything if the write time is not long enough to record to your SD card and you'll get empty files. 

3) Clean your device every time you take it out or see visible biofouling. Also, add silicon grease every time to your O-ring. Take it out with an O-ring pick and clean the plastic seal, looking for any type of sand/mud/debris. We've had a few flooding incidences, but this is probably because we open them all the time.  

4) lower the frequency rate the more data you can collect, so keep it as low as your frequency of interest without clipping your calls. Fish are lower than pretty much everything (2kHz-3kHz). 

I hope this helps!

WILDLABS downtime and performance issues due to AI bot attack

Hi everyone,Some of you will have noticed that WILDLABS was inaccessible or frustratingly slow on Friday (April 26th, 2024). Aside from explaining this downtime, what happened is...

1 10

I noticed the site being annoyingly slow some time last week. Thank you for clearing that up, for finding the cause and solving the issue.

I'm not claiming deep knowledge on AI, but as a member this community, I'd be happy to give you my insights.

For starters: I am not categorically against bots scraping 'my' content, whether for AI training purposes, search engines, or other purposes. In principle, I find it a good thing that this forum is open to non-member users, and to me that extends to non-member use. Obviously, there are some exceptions here. For example when locations of individuals of endangered species are discussed, that should be behind closed doors.

Continuing down this line of reasoning, apparently it matters to me how 'my' content is being used. So, if someone wants to make an AI to aid nature conservation, I say, let them have it. There is the practical side of scraping activities that may be blocking or hindering the site, but there may be practical solutions for this. I don't know, say, have special opening hours for such things, or have the site engine prepare the data and make it available as a data dump somewhere.

Since purpose matters, organizations or individuals wanting to scrape the site should be vetted and given access or not. This is far more easily said than done. However, every step in the direction would be worth the while, because most technology publicly discussed here has good use for nature conservation, but equally bad use for nature destruction. For example, it's good to acoustically monitor bird sounds to monitor species, but also comes in handy when you are in the exotic bird trafficking business.

One could argue that since we allow public access, we should not care either about why bots are scraping the site. I would not go that far. After all, individual people browsing the site with nefarious purposes in mind is something else than a bot systematically scraping the entire site (or sections thereof) for bad purposes. It's a matter of scale.

Hydromoth settings

Hi Everyone,what is your #HydroMoth setup for freshwater ecoacoustic monitoring? What are your settings for underwater recording with your AudioMoth? I would love to dicuss...

8 0

Hi Ian,

I have hours of an unidentified creature recorded during overnight recording sessions with mutliple hydrophones. We think it is platypus but there is nothing to compare against that isn't from captive sounds. I am waiting on the Hydromoth to become available again so I can do longer term monitoring.

Hi everyone, I just got my first hydromoth and wanted to test it for aquatic soundscape with interest in Tomistoma, Otter, boat traffic and maybe fishes too!  But before that I maybe test it on zoos.

What are your advices, tips, or suggestion for first-time user? thank you!

You won't get any audio if you don't allow enough time for the hydromoth/audiomoth to write. So when you do a continuous recording you need to experiment a little. I'm sure there is a formula to calculate this, but I haven't figure that out. I typically do 5 min recordings with 10 seconds of write/break time. I think this system is expecting you to subsample, so keep that in mind instead of a continuous recording. 

I do 8kHz sampling and get about 7 days of data and then the voltage gets too low and you start getting SD card write errors and missing files. 

In terms of analysis, I've had trouble understanding the directionality of the hydromoth and incorporating this into my studies. I always set up two at the same site to check the variability in my call detections and include this into my error analysis.

Attaching a directional microphone to a Wildlife Acoustics ultrasonic recorder?

Background: I am still new to acoustics research and I am hoping to get some advice on integrating a directional microphone with an ultrasonic recorder....

3 0

Hi Luke, sounds like an interesting project! One thing to note is the ultrasonic Wildlife Acoustics unit you're looking at is already fairly directional. Take a look at the horizontal directionality plot towards the bottom:

You can see that for the relevant frequencies for slow lorises ultrasonic calls (40-60 kHz), there is 25-30 dB difference between 0 and 180 horizontal degrees. It's not perfect, but is close to some directional mics, and if it works well enough for your project it would save a lot of time and testing!

If you do choose to integrate an external directional microphone, be careful with microphone placement to avoid potential ultrasonic reflections from any hard flat surface like a tree trunk, water surface, or the instrument housing itself. Here's an example of some echo calls from reflective surfaces from bat vocalizations: 

It would be helpful to hear how you plan on obtaining behavioral information (and what kind) to correlate with vocalizations? Observations, cameras, biologgers, etc.? This could inform responses a bit more.

Hi Jesse,

Thank you so much for your reply and for the fantastic knowledge and resources! I was unfamiliar with the plots, so thank you for providing some interpretation- I will have to work to better understanding them. This may change things (I was going off of experience from field work with the last iteration of this WA recorder which had omnidirectional recording) and I may choose to pilot the recorder without an external microphone this summer. 

Regarding my plan for collecting behavioral data, I plan to follow 15 wild individuals in a reserve in Thailand (mostly dry evergreen and dry dipterocarp forest with some human modified areas). I intend to use instantaneous focal sampling to observe lorises in two shifts between 18:00-06:00h. During these focal follows I will record all behaviors at 5-min intervals and use all-occurrences sampling for social and feeding behaviors, using an established slow loris ethogram. Simultaneously, I plan to record vocalizations, with the help of a research assistant and field guide. So we will be carrying the recorder with us during behavioral data collection. I intend to match up the timestamped loris vocalizations with the behavioral data to understand the call's function.

If you have the resources, I would suggest testing the sensitivity and directionality of the system at relevant frequencies both with and without an external mic, and let the results dictate which will be best for your case study.

Another thing to think about since you are manually taking the recordings is if a WA unit is really necessary. You're paying for the technology of a remote system without needing it. Other cheaper handheld recorders (such as Zoom recorders) could free up $$ for a higher quality directional microphone. Although of note is that common Zoom recorders like the H4n only sample up to 96kHz for which the upper frequency limit (48kHz) is getting very close to the frequencies you're likely wanting to measure.

Hi Phani,

An entry point might be to participate in a challenge related to conservation on:

You could also reach out to a conservation organization (e. g. WWF or something smaller and more local) and ask them directly whether there's an opportunity for you to volunteer, perhaps even suggest an idea and maybe they find it useful.

I hope you find an opportunity you're looking for!
