Understanding the difference between standard and reverse mortality modes can make all the difference in collecting accurate data in the field🔋

Our XM units offer both options to suit your study needs.

Standard mortality mode is ideal for active species, like birds, where a lack of movement may indicate a mortality event—triggering an increased or double pulse rate.

Reverse mortality mode, on the other hand, is designed for species that remain still for extended periods, such as during torpor or dormancy, and responds with a decreased pulse rate to help conserve battery life.

Choosing the right mode ensures more reliable data, longer transmitter performance, and better alignment with your study species’ natural behavior.

Every study species is different—and so is the way transmitters are attached.

We offer a wide range of attachment styles to suit different research needs, from epoxy mounts and collars, to implants and more. The right method depends on your species, study goals, and field conditions.

If you’re unsure which attachment style is best for your project, feel free to reach out to our team—we’re happy to help you find the right fit for your study.

It is with deep sadness that we learned of the passing of our dear former colleague, Donna Scott.

Donna was an integral part of our team for more than 10 years before retiring from HOLOHIL 10 years ago.

Our thoughts and heartfelt condolences go out to her family, friends, and all who had the privilege of knowing Donna.
Rest in peace, Donna. You will be missed. ❤️

Species Spotlight | Bog Turtle 🐢

One of the smallest turtles in the world—and the smallest in North America—this tiny species grows to just about 4.5 inches long. But don’t let its size fool you… bog turtles can live over 60 years in the wild.

Listed as threatened since 1997, their populations are impacted by wetland habitat loss, vegetation overgrowth, and illegal collection for trade. As their open wetlands become overgrown and shaded, the habitat they depend on slowly disappears.

Protecting and restoring wetlands is key to ensuring this small but resilient species continues to thrive.

How do I choose the right transmitter size for my species? 🐀 🐊

When it comes to wildlife tracking, size matters — but not in the way you might think...

A good rule of thumb: your transmitter should never exceed 5% of the animal’s body weight. This ensures it’s safe, comfortable, and doesn’t interfere with natural behavior.

From tiny songbirds to medium-sized mammals, choosing the right size protects the animal and keeps your data reliable.

Need help picking the perfect unit for your study? Reach out — we’re happy to guide you.

You asked, we listened! 🐾

Many of you wanted a feature on the XM series that does the opposite of our standard mortality—tracking animals when they go inactive instead of signaling death. That inspired our "Reverse Mortality" feature. After a preset period of no movement, the transmitter will lower its pulse to indicate dormancy, torpor, or hibernation, then it will reset to its original pulse when activity resumes.
