the claim

The California condor was saved from extinction by a captive breeding program.

the verdict
CONTESTED PARTIAL
Recorded sources
4 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the California condor was saved from extinction by a captive breeding program?

Partly. Several peer-reviewed items confirm that California condors were bred in captivity and that captive-bred birds were released as part of a recovery program, but none states that this program saved the species from extinction. One line of research argues the condor's apparent recovery depends on intensive ongoing management, so the evidence only partially addresses the claim.
