It takes about five or six years for a California condor to mature, so it will be a while before they will reproduce in the wild. We use the older birds as breeders. Within a few weeks of the airing of the show, there will be up to 10 more birds released. So, this program is constantly changing. Since they don't have the benefit of the parents out there, they sometimes get into trouble.
Power lines are a potential threat to condors.
They will actually land on them, or sometimes fly into them, because they don't always see them. So, if they get into areas where we think there is potential danger, we try to discourage them and bring them back in. Sometimes we will re-release them in a different area. They all have radio collars on them. They last one to two years, and we are still trying different types of transmitters and technologies.
