A hidden camera near one of the feeding sites is now taking still photos of all of the free-flying condors at Pinnacles National Monument as they balance on a scale, which has been disguised as a comfortable perch. The CondorCam allows biologists to track the weight of the birds, which gives an indication of physical health.

Biologists can check the status of the transmitters located on the condor's wings and see if the birds have been scavenging on food from outside the park. Some other activities the hidden camera captures are condors preening their feathers, fighting with other condors for the opportunity to stay on the scale, and other species investigating the perch.
