The California Condor has had a hard time living with humankind. From pesticides to lead bullets, we keep poisoning them.
At one point there were less than 30 of them left in the wild. They were collected up and a very successful breeding program was initiated. There are now more than 400 California Condors in the wild and captivity.
These two can't be released and their genetics are already too well represented in the California Condor population.
