Wildlife tracking technologies have already massively advanced our understanding of the natural world, from uncovering previously mysterious migration patterns and key movement corridors to demonstrating the impacts of anthropogenic pressures and climate change. Recent advances in the development of technologies for collecting and transmitting biologging data have unlocked the potential for fine-scale data collection at a near-global scale, which when integrated with remotely sensed environmental data offers an unprecedented biological lens into ecosystem health and environmental change (Jetz et al. 2022).
New technologies on the horizon include small satellites like CubeSats, which are being investigated by NASA, the ICARUS Initiative's satellite system, and a variety of other ventures aiming to improve the coverage, accuracy, and capacity of wildlife tracking data collection. Combined with the increased availability of high-resolution environmental data and analytical developments in movement modeling, these advancements are empowering movement ecologists to ask previously unanswerable or unimaginable questions. It’s clear that this discipline sits at the precipice of major breakthroughs that could revolutionize our understanding of animal movement and the natural world.
This role will be employed under Osa Conservation's Movement Ecology Program. Broadly, the project aims to develop and use novel animal tracking technology to increase our understanding of the movement ecology of...

non-invasive technique to apply GPS collars without catching?
14 June 2021 12:01pm
21 February 2024 7:27pm
That GNSS chip is indeed tiny!
29 March 2024 12:26pm
Reopening this discussion again. I am very interested in further testing a passive collar option used by Alaska Fish and Game in the early 2000's that did not gain support. The collar is based on hunting snare technology but is completely safe and non-invasive. It would primarily be a braided wire base with a LoRa tag attached with UV tabs for detachment and a safety breakaway. Is there a company that will design prototype collars for a fee utilizing their own GPS transmitter tech?

Hi @bcwheeler43 , I haven't used the radio-tracking.eu setup in particular, but it looks pretty similar (at least in principle) to Motus (https://docs.motus.org/en/about-motus/quick-reference/station-deployment). My experience with the Motus set up is that it can take a bit to get it all to work, but, there's a fairly active community here (https://sensorgnome.org/) that you might be able to get tips and guidance from. If you are looking for a more off-the-shelf option, have a look here (https://celltracktech.com/pages/digital-radio-products). They might even be able to help you get a system ready to detect tags and then activate your playback...
And in case any of it helps, whilst we didn't use VHF, here's a paper where we used UHF tags we designed to do something similar (https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/2041-210X.13651). See case study 2. All the files are released to open source, although some of the parts might be getting a little harder to find...I am hoping to an update soonish...You might have also come across Breck and co's old paper (https://escholarship.org/content/qt4gv9x4j1/qt4gv9x4j1.pdf) that has a little detail, although not really enough to build a full system.
Anyhow, I think a VHF version would be very useful as so many collars use VHF transmitters.
Please keep us posted with your progress!
Cheers,
Rob
28 March 2024 5:11pm
Thanks for this! I wasn't aware of your paper, so that's super helpful! One of the main reason we are aiming for VHF rather than UHF is that we thought the UHF tags wouldn't work to trigger the sound from as far away as we are hoping to. In any case, I'll send this along to my engineer and do my best to digest everything myself. I may get back in touch if you don't mind, and in any case will let you know how it works out. Thanks again!

Hi Peter, we manufacture solar powered Iridium trackers for birds, crocs/alligators and collars for various species. Our longest standing unit is a 55g unit on a Vulture and has been going for 4 years, providing data on an hourly basis. Our croc units include a pressure/depth sensor and provide details of depth and time at depth. Most of our devices include a VHF transmitter which is fully configurable over the air (you can change frequency, pulse duration, pulse interval and operation times - good for security).
12 January 2023 3:08pm
Hi Greg! Your Iridium tags sounds really interesting. I tried looking you up on
but there is not much to be found. Can you provide more details and images of your tags?

Hi Rob, Yes these are indeed the models. They are as reliable as the old originals. I have the GT120B's, G2S with/without solar and some GW's. Production has stopped and they won't be available in the future and I'm getting hold of their remaining boards. Have a big batch of GT120A's too which were only deployed once on a big seabird project which I will test at some stage and make available.

Need tips on best practices tracking turtles
4 March 2024 12:52pm
6 March 2024 1:24pm
Hi Gabriel,
Our TagRanger Tags can be used for tracking turtles, we already have a tracking project commencing soon in South America for ~40 turtles...
https://www.tagranger.com/
The Tags use LoRaWAN allowing you to communicate with your Tags in real time. As well as requesting current GPS locations from long distances away (20km Line of Sight) you can also use the integrated ranging tools which give you distance to your Tag in metres when you get closer.
Key features:
LoRaWAN (tested > 20km line of sight). Use a 'Finder' which is a handheld gateway or you can also use your own LoRaWAN network.
UWB ranging gives distance (in metres) to the Tag up to 150m away
Hybrid Ranging combines the equivalent of a VHF pinger from a few km away (line of sight) with the UWB ranging when you get closer
Log Download remotely using UWB radio
The Tag can last for very long lifetimes depending on how you configure it
Please drop me a line if you are interested in hearing more about this and how we could configure it best for your application.

Hi Andrea,
The OpenLog Artemis might be an option. I haven't used one of these yet, but its what I immediately thought of. Built in real time clock and IMU that records to microSD. It has four 14-bit ADCs and I2C connectors for the 'Qwiic' or 'grove' sensor boards. I'm not sure if it has programmable on/off cycles with the clock but you may find an existing project that does this.

Seeking advice for remotely retrieving high frequency acceleration data
28 January 2024 1:26am
28 January 2024 9:42am
Hi Maggie!
This sounds like a really interesting - and challenging project!
UHF is used for tranfer of acceleration data (along with other stuff like magnetometry and GNSS locations) by systems developed by companies like Milsar and TechnoSmart.
Ceres Wild uses satellite transfer over the GlobalStar but no raw acceleration data is transmitted.
I would fear the bandwidth would be too restrictive if you insist in using satellite based transfer of accelerometry.
Cheers,
Lars
29 January 2024 5:19pm
This sounds like a lot of fun!
The lowest cost satellite comm I know of is https://swarm.space/. It's pretty cool tech, but the data rates are quite low.
Do you have any idea how much data you need to move per day on average?
Perhaps LoRa would be an option? Here is an example of a LoRa device https://www.adafruit.com/product/4284
LoRa is not satellite, but it has quite a long range which may suffice? It is also pretty low data rate, but it is a good deal better than Swarm. The best thing about LoRa is that the end-point can be very low power, so battery life can be quite good.
If you know somewhere the crocs frequent, you might also be able to work something out with Bluetooth LE? Both LoRa and Bluetooth would require the installation of at least one base station. Lora's base station could be substantially further way.
11 February 2024 2:33am
I have a few suggestions Maggie. Hopefully one or more will be useful.
Preprocessing - Compressing the data before transmission will reduce file size and reduce transmission time.
Reduce data volume - I guess the animals are only active for some periods and a lot of the time are just "cruising along". So a useful strategy could be to only start recording when a certain threshold of acceleration occurs. And if you also buffer the data for say 10 seconds, you will get info about what's leading up to the activity. And adding a GPS module you will get some info on where the activity occurred plus movements prior. This will of course increase the data volume but only recording the most recent location will probably suffice as the location of the previous activity will tell you how far the animal moved.
Use LoRa instead of satellite - LoRa is well suited to this type of application. I saw in
that the home range of crocodiles is relatively small so although a forested area will limit LoRa performance, the range should be sufficient. You could also use multiple base stations if needed.
Of course eventually the data that has been recorded at the LoRa base station(s) will need to be collected. You could add a long range radio to the base station, or just collect the data 'manually'.
Hope this helps

Hi Krasi! Greetings from Brazil!
That's a cool journey you've started! Congratulations. And I felt like theSearchLife resonates with the work I'm involved round here. In a nutshell, I live at the heart of the largest remaining of Atlantic forest in the planet - one of the most biodiverse biomes that exist. The subregion where I live is named after and bathed by the "Rio Sagrado" (Sacred River), a magnificent water body with a very rich cultural significance to the region (it has served as a safe zone for fleeing slaves). Well, the river and the entire bioregion is currently under the threat of a truly devastating railroad project which, to say the least is planned to cut through over 100 water springs!
In face of that the local community (myself included) has been mobilizing to raise awareness of the issue and hopefully stop this madness (fueled by strong international forces). One of the ways we've been fighting this is through the seeking of the recognition of the sacred river as an entity of legal rights, who can manifest itself in court, against such threats. And to illustrate what this would look like, I've been developing this AI (LLM) powered avatar for the river, which could maybe serve as its human-relatable voice. An existing prototype of such avatar is available here. It has been fine-tuned with over 20 scientific papers on the Sacred River watershed.
And right now myself and other are mobilizing to manifest the conditions/resources to develop a next version of the avatar, which would include remote sensing capacities so the avatar is directly connected to the river and can possibly write full scientific reports on its physical properties (i.e. water quality) and the surrounding biodiversity. In fact, myself and 3 other members of the WildLabs community have just applied to the WildLabs Grant program in order to accomplish that. Hopefully the results are positive.
Finally, it's worth mentioning that our mobilization around providing an expression medium for the river has been multimodal, including the creation of a shortfilm based on theatrical mobilizations we did during a fest dedicated to the river and its surrounding more-than-human communities. You can check that out here:
Let's chat if any of that catches your interest!
Cheers!

Questions regarding the use of solar panels to extend battery life of GPS collars
6 January 2024 8:44pm
24 January 2024 10:45am
With a Vectronic Vertex Plus 2D collar, 32Hz 3D acceleration and 15min position fix intervals you can expect between 3-6 months of lifetime using Iridium as position transfer.
This project seem to be using both 2D and 3D sized collars on lions:
https://www.vectronic-aerospace.com/projects/#KopeLion
28 January 2024 10:27pm
Lars,
As always, your insights are great! The GPS Plus X battery life calculator is great! I've downloaded it and have been toying around with it, very convenient when thinking about sampling schedules. Curious as to why more tech developers don't incorporate something similar into their own programming/analysis software. Very useful.
I've got a few meetings set up with a couple different tech developers, but may reach to Vectronic here. At first glance, their collars seem great! I appreciate the recommendations.
I must admit, I am not well versed in Python, but I am looking into something that wold be the R equivalent. If I don't have much luck, I may try and take a look at how that package was made in Python and attempt to recreate it in R.
You're the best Lars! Thanks!
Cheers,
Travis
28 January 2024 10:42pm
Hi Bill,
I don't believe I will need them to be extremely accurate, but will need a good degree of accuracy for some behavioral classification and habitat use analyses. In regards to the solar, tracking the solar cycle is a great suggestion. I have also considered having some thresholds programmed in the accelerometer to power off both sensors during periods of sleep/rest in order to conserve battery life. I did this same thing in my last study for the GPS only, so there wouldn't be instances where the trackers continued to try and unsuccessfully acquire GPS fixes while the bats where inside their caves resting. After the bat's surge axis dropped into the -1 and there was 10 unsuccessful GPS fix attempts in a row, the GPS powered down.
Thanks for the suggestions and insights Bill!
Best,
Travis
