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.


Pangolin Tagging Challenges

Hi! I'm looking for information on Pangolin transmitters or sensors, the basics to start off with. What information is gathered specific to this species or what are the...

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!

movedesign: a tool to evaluate sampling design in biologging

This paper discusses movedesign, a new R app intended to evaluate the effectiveness of sampling design in animal movement research projects. This tool could be incredibly helpful for biologging community members looking to increase the effectiveness of their projects by better understanding the best duration and intervals for data collection.

Collar Tracking vs. Camera Traps for Monitoring Mexican Wolves

This article compares and contrasts the success of their wolf monitoring efforts with both collars and camera traps. The camera traps were intended to help researchers identify individual wolves within the population, but they experienced difficulties identifying both uncollared wolves and those with marked collars.


GPS collaring study of Ethiopian wolves

This news article discusses the first study to track Ethiopian wolves since 1992. The study focused on adult wolves from six packs in the Simien Mountains and used Lotek LiteTrack Iridium 250 collars. Community members working in biologging with species that are rarely studied will be especially interested in this effort to understand the wolves' behaviors and how human presence may be impacting these packs.


Feathered forecast: Tech tools comb weather data for bird migrations

Since its launch in 1999, the BirdCast project has used weather radar data to track and forecast bird migrations across the U.S. In recent years, technology such as cloud computing and machine learning have helped make the work of researchers in the project easier and more automated. The BirdCast project is now working on integrating radar data with human observations and bioacoustics to help identify the bird species traversing the skies.

Hi again Emily,

@tom_august just pointed to this PhD thesis in another post that could be of interest to you also:

All the best,


Not what you asked for (sorry), but if they are cryptic then a possible first step could be to deploy capacitive sensors everywhere, to get a sense of where they like to hang out and when.  I'm thinking of TTP223 touch sensors attached to a data logger.

Thanks for the link, Amanda. That Shark page looks great. Very good point on temporal resolution and the burden of overhead of sending data in real-time, I hadn't really considered that.

In addition to those noted, you can try the Animal Telemetry Network

Spring is our busiest time of year and we are also in the middle of an expansion currently so they may not be able to respond. Will ask when they are prepping for variety hour.

Hi Lars,

I can chime in to answer some of your questions. 

1. The web portal is here. This is only a basic placeholder while we work on a better system with login security and 2 way comms.

Send me a PM to see one our test Elk in Jackson, Wyoming.  

2. Our data is always transmitted sequentially, oldest samples first. 

3. Currently our staff must do any remote reprogramming, just send us an email. This feature will be part of the new web portal.

4. Iridium allows up to 340 bytes per SBD transmission. Each sample is 17 bytes so we can fit 20 samples per transmission. With good signal we can clear out a backlog of data almost immediately. 

5. Currently no geofencing or alerts but that is on the road map. 

6. As Brett stated. 

7. As Brett stated we are not going to support traditional VHF since this has caused many problems with poachers and wildlife photographers finding the animals. We are developing our own 900MHz LoRa based system which will securely transmit the devices location.This will be released in the form of a USB doggle with antenna that can be plugged into an Android device.

In regard to your questions about accelerometer and Doppler shift.

We have an onboard accelerometer sampling at 50Hz and currently this information is fed into a human calibrated pedometer algorithm. Currently it gives us a rough indicator of how busy the animal is. This sensor could be repurposed based on customer needs. 

Every time an iridium device transmits information, the receiving satellite records a rough position based on doppler effect from the signal. This gives you a backup geo-location with accuracy in the kilometer range. If you use the above tool and click download CSV you can see this information. 

Happy to answer any more questions. 

Hi Jackson @MargoJack!

Thanks a lot for answering these questions.

Looks like you have a very interesting product!

Interesting point you raise with VHF beeing intercepted by poachers etc.

Would there be sufficient memory to log accelerometer data at something like 8Hz on-board the collar for later inference of behaviours?

Will you make versions for other LoRa frequency regions?

Oh, great link! Been doing marine projects recently and a big headache is protecting submerged electronics. I've kind of heard of many of those techniques, but great to see them collected all in one place and with first hand experienced commentary regarding them. 

Not sure exactly how your telemetry will be deployed, but if it's going to be attached to an animal in a relatively non-invasive way, you might check with zoos or aquariums that have similar species. 

I worked in that industry for a long time and we tested telemetry for seals, sea lions, polar bears and elephants. There might have been more, but that's all I can think of off the top of my head. This can help improve attachment methods and test how tough the animals will be on the equipment.

Thanks Thomas! 

I haven't found any wing-tag avian trackers like I described. Although, similar models have been made for terrestrial animals in the form of ear tags.

I am inquiring as to whether a lighter version can be made for birds. Although an obvious concern is the weight of the tracker since the wellbeing of the bird is our priority.
