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 Becky,

Have you considered the Kestrel Drop D2? They're significantly cheaper at $99, but not rechargeable. They take button batteries, but these last a long time with standard settings. They connect to an app on a phone, but can store large amounts of data before needing to be synced. The one thing to be aware of is that you should make some kind of rain cover to hang them from, because the humidity sensor is exposed, so if it gets wet, it will just show 100%... 

Cheers,

Nick

Collar Tracking vs. Camera Traps for Monitoring Mexican Wolves

Ellie Warren

5 May 2023 9:08pm

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

Ellie Warren

5 May 2023 12:55am

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

Stephanie O'Donnell

26 April 2023 2:50pm

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.

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.

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. 

https://margosupplies.com/us-en/luminous/

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. 

Lars Holst Hansen

14 April 2023 8:38am

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?

Cheers,

Lars

Gwen Harris

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.

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.

Our project in very short is, setting up a sensor network for monitoring airborne biomass, mainly insects, birds and bats in near realtime, and to develop a forecast model to be used for mitigation with respect various types of human-wildlife conflicts (e.g. wind power, pesticide application, aviation). Our expertise is mainly in radar monitoring, but we aim on add insect camera information to be merged with the quantitative biomass measeurments by radar.

These are really small acoustic tags. (Lotek Wireless, Sonotronics, and the JSATs design are examples of similar manufacturers/products.) These tags will only work in water because they require water in order to propagate their signal. Of course that means you need receivers in order to pick up the signal, so usually organizations will have a string or strings of strategically placed receivers to pick up the acoustic tags (mouths of rivers is a common location). I think the Ocean Tracking Network (OTN) operates some of the largest sets of receivers. Others are managed by the institution themselves, various regional IOOS offices, and/or similar. 

They could work on really small sea turtles, but you are limited to tracking them based on the range of the receivers (which for smaller tags is even more limited, measured in meters or hundreds of meters). Lotek Wireless recently started producing their "Sunbird" line which has been used on some relatively small turtles. You can look at the work that Upwell is doing as an example of satellite-based tracking with very small turtles.
