Captive Breeding and Reintroduction

When Wild Populations Fail

Captive breeding is a last resort for species whose wild populations have declined to non-viable levels. The California condor—reduced to just 22 individuals by 1982—was brought into captivity for an intensive breeding program at the San Diego Wild Animal Park and Los Angeles Zoo. Using techniques like double-clutching (removing the first egg to stimulate a second laying), puppet-rearing (to prevent human imprinting), and genetic management (studbook records ensuring maximum outbreeding), the population grew to over 500 by 2024, with more than 300 living in the wild. Similar programs have saved the Arabian oryx, black-footed ferret, and Mauritius kestrel from extinction.
