Biologging / Feed

Real-time tracking of animal movements is enabling more effective and efficient wildlife monitoring for management, security, and research. As devices get smaller and prices drop, the possibilities for using biologging on a larger scale have grown, and so have the possibilities for increasing customisation to meet specific research needs. Likewise, real-time tracking of illegal wildlife trade, timber, and fish products as they move from source to consumer can shed light on trafficking routes and actors, as well as support enforcement, making tracking gear a powerful tool beyond the field.

Hi Caitlin,

you might also look at this RFID logger sold by Labmaker:

Greetings from Austria,



Hi Caitlin

I'd recommend who from past experience will work with you to come up with a good trap design. Their approach is to use an IR to detect when an animal starts to pass through the detector, which then triggers the RFID coil to be powered up. The huge advantage of this method is the battery power required is then very low, and the data can be stored into an SD card, all in one cheap, self-contained unit.

Hi Tobias! 

This sounds great and I am looking forward to trying it out after returning from field work! 

Very cool with the Vectronic Activity data! I am looking forward to check How we can use that!

non-invasive technique to apply GPS collars without catching?

Dear all, I was wondering if they were "passive" techniques to "install" GPS collar or other GPS devices on a terrestrial animal ? Just a discussion...

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. 


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:

prototype collaring station

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:

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

Argos Eartag Transmitter

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.

Thanks for all these interesting information, I'm sure that such technology will be developed in the future to dramatically reduce cost and risk of collaring such animals.

Icoteq are launching a new range of small tags that would be ideal for pangolin tracking!

Called TagRanger, the technology incorporates a LoRaWAN based tag with built in sensors and GPS.  It also features a ranging solution giving you your distance to the tag when within range <150m - ideal for finding something which is well hidden as you can navigate your way to the tag until it's within touching distance!

The user carries a small handheld 'Finder' device that acts as a LoRaWAN gateway paired to a mobile phone for live mapping (on and offline maps) and ranging functions.

Size is limited by your preferred battery size, but could be as small as 32mm x 38mm x15mm with a 400mAh battery.

Production units available beginning of September, happy to do demos and trials with prototypes now!

Please feel free to contact me for more information.



We have been working with Save Vietnam's Wildlife to track Pangolins for a couple of years now. You can read our Case Study here: 



We also documented the project and spoke with Save Vietnam's Executive Director about the challenges of tracking Pangolins - here is the video: 

They used the Telenax pangolin tags (15g) during our project which worked great with our drone-based telemetry system and were able to receive signals from a long distance. Feel free to reach out if you have any questions, we are always happy to discuss tracking projects!
