What are the primary methods used by researchers to track and study the behavior of elusive big cats like the jaguar and snow leopard in the wild?

Researchers use a variety of methods to study elusive big cats, including GPS collars and satellite tracking, camera traps placed along trails and water sources, and genetic analysis of scat samples. GPS collars provide real-time data on movement and habitat use, while camera traps capture images of the animals in their natural behavior. Scat analysis helps identify diet and health information.
