Image: Tracking Mountain Lions

Description: January 2013 - US Fish and Wildlife Service employee Mary Jo Hill attempting to locate two radio collared mountain lions siblings (a male and a female) with radio direction finding equipment. They had been collared in December 2012 and we knew they were traveling with one more male sibling who was not collared. Using their locations we were able to track and collar the last male sibling. The animals have small radio transmitters on collars around their necks that emit a low-powered radio signal in the VHF band. The employee holds a RDF radio receiver with which she can hear the signal. She turns the Yagi antenna she is holding until the signal is strongest in her earphones; then the antenna is pointed at the animal. Credit: Carmen Luna / USFWS
