Instead of names, every California condor is identified by a “studbook” number, assigned on their hatch date. A studbook is a breeding registry that helps managers document and keep track of pedigree and individual birds. The lower the studbook number, the older the bird is. Each bird is visually identified by a vinyl ID tag on one or both wings. The color of the tag correlates with the age of the condor.
