Wild California Condors Made Here
Sep 28, 2012
By 1982, fewer than two dozen California condors lived in the wild. By 1985, only one wild breeding pair was known to exist. That’s when the U.S. Fish and Wildlife service decided to capture any remaining condors and bring them to live–and breed–in captivity. The Peregrine Fund, in Boise, Id., houses the largest California condor breeding center in the U.S.–with nearly sixty California condors living on site. Bill Heinrich and Taiana Carvalho take us “behind the enclosure” for a tour of the condor compound.

California condor recovery reaches landmark
200th California condor chick hatches at The Peregrine Fund‘s captive breeding facility
May 2013. A tiny California condor chick marked a major milestone for The Peregrine Fund. It was the 200th chick to hatch in the conservation group’s captive breeding facility since joining the effort to breed endangered condors in 1993.
20 eggs this year
The captive breeding facility at The Peregrine Fund’s World Center for Birds of Prey is home to 62 condors, the world’s largest flock of captive condors. This year, 18 pairs produced a total of 20 eggs. When the chicks are about 9 months old, they are transferred to The Peregrine Fund’s release site near the Grand Canyon in Arizona, where they join the wild flock, which currently numbers 72 birds.
“We are thrilled to reach the 200 mark,” said Marti Jenkins, who oversees the condor propagation program. “Every chick takes us one step closer to saving this magnificent species from extinction.”
Wild foster parents
The Peregrine Fund works closely with three other facilities – Los Angeles Zoo, San Diego Zoo Safari Park, and Oregon Zoo — that raise California Condors. This year, two of the eggs produced in Boise were placed in the nests of wild condors in California to replace eggs that were not viable. Both eggs hatched and are being reared by their wild foster parents. A third egg was transferred to the Oregon Zoo and also hatched successfully.
“We will be sending at least one more egg out to replace one from a wild nest in California,” Jenkins said. “Such swaps promote genetic diversity in a small population and enable this program to be as successful as possible.”
The captive breeding process bolsters wild breeding numbers, Jenkins said. This year, Peregrine Fund biologists have observed six wild condor pairs exhibiting incubating behaviours in the rugged canyon lands of northern Arizona.
An intensive condor recovery program began in the early 1980s when the continuing decline of the condor population required drastic measures. By 1982, only 22 condors remained on Earth. The last birds were brought into captivity to launch a breeding program. The first releases to the wild occurred in California in 1992. The Peregrine Fund began raising condors in 1993 and releasing them to the wild in 1996.
Today, there are more than 400 California Condors, with more than half of them flying free in the wild in Arizona, California and Baja, Mexico.

Prior to reintroduction, the last wild condor in Arizona was sighted just south of the Grand Canyon in 1924.
Condors reach maturity at about six years of age. They usually produce one egg every other year.
The condor is the largest land bird in North America. The birds can weigh up to 26 pounds and have a wingspan up to 9½ feet.
Condors were added to the federal Endangered Species List in 1967.
Lead poisoning is the leading cause of death for California Condors in Arizona, with 26 deaths confirmed since 2000.
A comment on this at the Wildlife Extra site:
The California condor almost became extinct, but captive breeding has brought back their numbers. But they are being threatened again by lead poisoning. An alternative source has to be discovered for ammunition, or they could end up becoming on the verge of extinction again.
