I suspect she's the only condor in the wild right now without a radio transmitter attached. Although it won't last, I kinda like that idea (may there be many more).
Actually, there are at least a couple others in central California right now, and perhaps one or two in southern California as well. Some of the nest sites are so remote that we can't physically reach them while condor pairs are nesting, and we wait to place tags on them until the fledglings arrive at managed feeding sites with parents. Other nests are too challenging or dangerous - for the safety of the biologists, nestlings, or both - to safely catch and handle birds to place tags and transmitters in the nest sites. For the Pinnacles condor fledgling, the lack of a tag right now was due to the latter.
