Modern tracking technology for raptors has advanced rapidly, allowing researchers to monitor movements with unprecedented detail using tools such as GPS tags, Motus radio transmitters, and cellular or GSM-based tracking units. These devices, which vary widely in size and capability, can record fine-scale locations, long-distance migrations, and real-time movements depending on the technology deployed. Because raptor species differ in their life histories, migration strategies, habitats, and overall body size, transmitters must be carefully matched to each species to ensure both the welfare of the bird and the quality of the data collected.
