Condor Monitoring
Monitoring and managing the wild flock-what it takes to keep condors soaring
Radio and GPS/Satellite Telemetry:
High-Tech Tracking Devices
Prior to release, all of the condors are fitted with either a radio or a GPS/Satellite tag on each wing. Radio transmitters weigh approximately 2 ounces, and have batteries that last from 1 to 3 years. The more advanced GPS/Satellite tags weigh slightly more, but can be solar powered for up to several years. They provide much more detailed location information, but they are very expensive.
You might be lucky enough to catch a glimpse of condor biologists tracking birds from public roadsides near the park. Neighbors can lend assistance by reporting condor sightings or feedings and by allowing biologists access to lands in support of monitoring activities. Biologists will always ask for permission before accessing private land.
This map shows the current range of the Pinnacles and Big Sur condors. GPS/Satellite tags record the location of each bird once each hour, allowing biologists to keep track of the condor's movements. Approximately 1/5 of the population is outfitted with GPS/Satellite tags.
