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.

Good luck!
2 February 2023 1:47pm
Hi Huascar, how are you? there's limitations on snakes since their body form and behaviour, if you leave a VHF or GPS tag as an external fixation it will get tangled with roths and branches and it will fall, besides you have to suture and it can cause infections.
So far you only got implanted VHF transmitters, that's the most common, lonlasting and safe fixation method.
There's an alternative of using Tegaderm as a external fixation method but with ecdysis will eventually remove it.
any doubts please write me [email protected]

3D model of custome-made GeoTrak GT-65GS-GPS with slanted front face (adapted from http://www.geotrakinc.com/products/solarGPS/PTT-65g-solarGPS.html).
Known flaws: Size and shape of attachment loops are not correct: the actual material is too thin to allow for a strong 3D printing so I decided to make the loops thicker; the actual loop hole is also slightly wider. Base of antenna is shorter than actual one. Actual device has smoother angles and slightly convex top (where the solar panels are).
The 3D print will need to be sanded to smoothen the edges and to get the soft angles of the original design. I also designed the tag with a hole where the back solar panels should be: this is to add weight (metals nuts and bolts) to reach a final mass of 65g.

Hi Matthew,
I am not entirely sure how the collars have failed since we loose them after failure despite a big effort in recapturing the animals. In one case where we did recapture, the UHF long range communication was gone but data was downloaded after the collar came in near visinity of the base station. Ecotone makes a similar collar with a drop-off mechanism but I have not tried it.
12 January 2023 1:56pm
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?

NomaTrack and the LoRa-DTN protocol
26 March 2021 8:26pm
LoRA is registered in most places. With Starlink offering more and more service it would be possible in the future to transmit remote images through satellite once it is available in Madagascar. Power consumption of Starlink is big though.
4 January 2023 2:07pm
Hi Carly!
Since LoRa and LoRaWAN are meant for low bandwidth data it is not really feasible to use for transmitting remote audio and image data. It could be very valuable to have metadata like battery levels and trap "levelness" sent back to get an idea of the power and physical state of the traps. I am dreaming of something like this for our remote camera traps used for monitoring arctic fox dens in Greenland. They are not rarely turned over by muskox and polar bear and we are consequently loosing important data.

non-invasive technique to apply GPS collars without catching?
14 June 2021 12:01pm
6 January 2023 8:36pm
Yes, this is not very long considering the effort it takes to capture and tag a polar bear!
6 January 2023 11:07pm
It's a start though! Always happy to see people trying to innovate. Also I thought the intent was that they wouldn't need to capture the bears like you would for a collar? We were imagining a passive system where you would have an attractant and tags could be applied to a bear by rubbing against something.
8 January 2023 5:14pm
Hi Brett! The original poster @antoineede surely asked for automatic non-invasive deployments and it was intriguing to see that someone actually made such a system for mule deer as @Rob_Appleby pointed out. Here is a prototype from their paper:

I would love to see the wolf example too @Rob_Appleby, if you can find the reference.
In the polar bear example it was never the (initial) intention that the animals should not be captured.
It seems that they are basically looking for an alternative and less permanent way to attch the ear tags.
Here are some prototypes:

Image from:
It looks like they are actually using these Argos tags from Telonics:

I am generally a bit sceptical regarding a fully automatic tracking device deployment system. In most cases, a lot of measurements (size, weight) and samples (hair, blood, saliva etc.) are taken and observations (sex, age stage, breeding condition) are done and any meta data will increase the value of the tracking data itself tremendously. Also, one might want to sometimes decide not to tag some individual because of some unforeseen condition. I would rarely just want some random collection of tracks from a number of animals you know nothing about. What about the challenge of simply restricting the system to tag only the targetted species? I guess a deliberate use if AI and computer vision could get some of these data but it is going to make the development of the system quite complex.
I still find it very interesting to follow the developments.
RFID Smart traps
23 April 2021 9:10am
5 June 2022 10:31pm
Hi Caitlin,
Years ago we designed a sort of similar 'trap', although it did not have the ability to actually capture/hold an individual. Our idea was a two capture occasion process: the first where animals in an area were physically captured and outfitted with RFID. Then, for a second capture occasion, we placed our 'traps' in the same area, with each trap having both an RFID logger and a trail camera. That way, we knew whether an individual caught on camera had an RFID tag or not (i.e. by comparing timestamps) and could work out if it was a new individual. Traps were actually tunnels made out of PVC drain pipe with two entrances/exits (so an animal wouldn't feel trapped), each of which had an RFID antenna fitted to the outside. The camera sat at the back of the tunnel so it could record animals entering or leaving from either entrance. Here's a picture:
The RFID logger we used was this (LINK) although it looks like it's sold out. It had an auxilliary daughter board that could be used for the second entrance antenna (LINK). Antennas we used were these (LINK).
We never got to do a lot of testing, but in a pilot study it seemed to do ok. I am happy to share any relevant files etc., I have to build it all, but it sounds like you need something a lot more sophisticated. The logger from @sam_octanis looks amazing and so does Sarah Knowles'.
I was always keen on exploring the next logical step of this process to which was actually a device that could deploy tags if an animal wasn't tagged. Our idea was something akin to an 'orchid' which deposited a tag on the back of an animal while it was a feeding source. We figured some sort of glue would probably work (e.g. UV cured glue) although retention rates would be interesting. Might be long enough for a two or three capture occasion study though...
Anyway, I am happy to help if I can and could even send some of our gear to @Freaklabs if you end up collaborating as they no doubt could build a very suitable system for ya.
All the best,
Rob

You could also get in touch with ICARUS program at Max Planck (https://www.icarus.mpg.de/en). They've developed a new tracking system, with their own first reciever on the ISS. I think there are some limitations on the availability of their tags now as they're still ramping up their program.

Regarding the accelerometry I am curious to know which frequencies are supported. Have you considered magnetometry, too? This could obviously be useful in dead reckoning but also for inferring behavioural states (as shown in this paper).

Thank you Steph, I understand, my apologies everyone!:)
28 November 2022 11:01pm
Hi everyone, I’m not sure if this thread is still active, but i recently had a few clients asking for VHF trackers for assets being transported, I’ve created a few micro transmitters the last few weeks, extremely lightweight, steady & strong signal, variable pulse options, using a .3mm Nitinol wire for antenna, as well as the smallest discrete smd components on the market, but best of all the transmitter is able to steadily pulse for approximately 310 days using a silver oxide 1.5V button cell battery (imagine the transmission time with a few thousand mAh battery if size/weight wasn’t too critical), with a 20ms pulse every 1.2 seconds, I’ve attached pics to show size. if anyone is interested in making your own just message me please, I’d be happy to share build schematics and BOM, I have also made gerber files for anyone that wants them manufactured!
The transmitter should of course be incapsulated but here’s a PCB-less version to show you just how small it is.

I'll add - avoid fast curing resins/epoxies for, at least, two reasons:
1. The exothermic reaction between the two compounds can cause sensor issues (ie: heat).
2. Air bubbles will form (and cure) more easily in fast curing compounds.
23 October 2022 2:51pm
Thanks Thomas!! We do use slow curing resins with no heat generation
Conservation Technology Intern (Vietnam)

27 January 2023 1:30pm
Hi Hari,
A simple test we do is pump the unit up slightly (maybe 1 psi), and check for bubbles. It's like fixing a flat on a bicycle. The positive internal pressure opens up and exposes any questionable seals. Most of the leakage problems tend to be of the shallow water variety, which this test finds. Deep water leaks are more rare, since the pressure tends to close up any cracks.
Otherwise the SOP is to lightly grease all O-rings and seals, and assemble the unit in the lab to prevent sand etc. from sticking to the greasy O-rings.
Thanks
