One subadult male specimen of a reintroduced mountain lion was monitored using the radio telemetry technique. The monitoring lasted 110 days, being randomly distributed. Data of the monitoring through radiotelemetry suggested that the home range of this specimen was of approximately 26km². This sets as the smallest home range described for this species. However, the importance of this basic monitoring should be emphasized, since information of the behavior of a large feline reintroduced in its natural habitat after a period in captivity is incipient.
