Rethinking terrestrial wildlife telemetry through instrumentation without capture and handling

The Takeaway
Traditional wildlife tracking requires chasing down animals and injecting them with dangerous chemicals to put a collar on. A new autonomous system uses a remote mechanism to gently latch a sensor onto an animal as it passes by a feeding station. This eliminates the extreme stress and potential death that often comes with standard capture methods. It allows biologists to study nature's most elusive creatures without interfering with their natural behavior.
From the abstract
Telemetry using animal‑borne biologgers is central to wildlife research. Capturing and instrumenting wild animals, however, remains the most invasive, logistically challenging, and costly component of telemetry studies. This has contributed to current practice, which favors long tracking durations on few individuals, prioritizing longevity over temporal detail. While this model has yielded important insights, it also imposes ethical and scientific constraints. I argue that less invasive deployme
