Quite the trick.

In an early proof of concept, an automatic system puts a GPS collar around a red deer’s neck as the animal sticks its head into a small cage tied to a tree, lured in by food.Richard Bischof/Norwegian University of Life Sciences Richard Bischof, a wildlife biologist at the Norwegian University of Life Sciences, sees a better way forward for this field of study, known as wildlife telemetry. He’s now building and experimenting with devices, described in a recent preprint, that would allow researchers to apply collars on animals without needing to capture them. Rethinking how we put collars on animals, Bischof argues, could bring many benefits to wildlife research, such as improving animal welfare and the quantity and quality of data collected at the same time. Remote Collaring Wildlife. At some point, drones will do this? The above in the video screenshot worked but I can see room for endangerment.
