Why can’t biologists learn more about the species through less invasive means?
A. For some species they can. Species that are common and easily observed can often be studied thoroughly without much, if any, “hands on” techniques. But for animals that are uncommon and/or highly secretive, such as jaguars, other techniques must be used. Without the complete data that can be provided by a tracking collar, biologists would continue to just have “dots on the map” without any means of connecting them. Tracking collars are one of the most common and effective tools used by biologists to understand and study wildlife populations.
