LOS ANGELES-Seven endangered California condors, about 20 percent of Southern California’s population, have been found with lead poisoning.
The birds started turning up sick about a month ago during random trappings at Bitter Creek National Wildlife Refuge in the San Joaquin Valley.
One of the birds died during treatment at the Los Angeles Zoo and four others are still being treated there. A chick and its mother were sent to the zoo to undergo treatment.
Officials don’t yet know the source of the contamination, but a U.S. Fish and Wildlife official said the birds were likely poisoned by eating the carcasses of animals that had been shot by hunters.
Lead poisoning is a known threat to the majestic birds and the main reason the state is about to ban hunting with lead bullets.
Jesse Grantham, a U.S. Fish and Wildlife condor coordinator, called the poisonings alarming and said the agency was in “crisis mode.”
The California condor nearly went extinct in the 1980s, but a trapping and breeding program has helped restore the species. There are only about three dozen of the endangered birds in Southern California, and about 200 in the wild overall.
Experts believe lead poisoning is a major factor in preventing the species’ recovery.
Under a ban that takes effect July 1, it will be illegal for California hunters to possess or fire lead ammunition when they are in the birds’ habitat.

March 2010. Biologists at Pinnacles National Monument in California have verified the first California condor nest in the Monument in over 100 years. Condor 317, a female released at the monument as a 1 ½ year old bird in 2004, has paired with a six year old male, Condor 318, originally released along the Big Sur coast by Ventana Wildlife Society, here.

August 2010: A coalition of conservation, hunting and veterinary groups in America have filed a formal petition with the Environmental Protection Agency requesting a ban on the use of toxic lead in hunting ammunition and fishing tackle. Major efforts to reduce lead exposure to people have greatly reduced the amount of lead in the environment, but toxic lead is still a widespread killer in the wild, harming bald eagles, trumpeter swans, endangered California condors and other wildlife: here.
