Ever wondered how mountain lions get collared? Follow along with Yellowstone wildlife biologists like Dan Stahler as he takes you through the steps of safely darting and collaring these incredible animals. Integrating snow-tracking surveys, DNA samples collected from hair, scat, and blood left by cougar, statistical modeling, GPS collars, and remote cameras are all tools used wildlife biologists to estimate cougar population sizes in Yellowstone. GPS collars also are used to study predation patterns and interactions with other species.
