Answer:
by using GPS labels
Explanation:
Different sensing technologies are nowadays used to track animal movement. In particular, terrestrial animal sensing technologies include, among others, Global Positioning System (GPS), radio telemetry, acoustic telemetry, environmental sensors, automated data-retrieval, etc. These technologies allow us to learn more about animal behavior and provide useful information for ecological/environmental researchers. In the case of GPS, satellite networks can be used to track migratory patterns.
