There is little doubt that the California condor is with us today as a result of human management of the species. One critical component of this management has been captive rearing. In the most intensive form of captive rearing, humans take the role of condor parents starting when an egg is laid.
In this post I consider intensive captive rearing from a visual perspective. The photos (and an illustration) below “describe” the hands-on rearing process in a way that words cannot.
The previous post to this blog, Extinct in the wild: news reports – part 1, concerned newspaper reports published the day after the “last wild” California condor was captured on 19 April 1987. This post looks at magazine articles published during the months following this critical event in the history of condors and humans.
Thirty years ago today, 19 April 1987, the “last wild” California condor was captured and taken to the San Diego Wild Animal Park.
In this post I note reports of this event that were published the next day in 4 major newspapers. I also show an editorial cartoon that appeared in the Los Angeles Times 2 days after the capture.
Beginning in the 1950s, those concerned about the California condor debated how best to prevent their extinction. Two main alternatives emerged: protect condor habitat and leave the birds alone, or intensively manage the condors, including breeding them in captivity. In the 1980s, the latter strategy won out and has demonstrated success.

However, the survival of California condors continues to depend heavily on human intervention. For example, condors living in the wild regularly experience lead poisoning that requires a return to captivity for veterinary treatment. Condors are exposed to lead primarily by consuming carrion that contains fragments of hunters’ bullets.
I recently encountered a book chapter that gave me new insight into the 20th century debate about how to insure the California condor’s survival. The chapter also considers possible futures for the California condor and for the relationship between the condor and humans. This post offers some reaction to this book chapter.

How much does a California condor cost? What is the value of the California condor? What is the California condor worth?
These questions have been considered and answered repeatedly for over a century. In this post I offer some examples.
From the 1980s, here are news photos of some of the first California condors hatched in captivity.
We now know that California condors can be bred in captivity. But humans gained this knowledge only in 1988 with the hatching of Molloko at the San Diego Wild Animal Park. This chick was the first California condor to be hatched from an egg produced by 2 captive parents.
Years of research had preceded Molloko’s hatching. But long before this successful research program began, there was an unsuccessful effort to breed California condors at the National Zoo in Washington DC.
