Lead causes an agonizing death in condors, slowly shutting down their organs, Jennifer Fearing, the director of California’s Humane Society, recently reported in a news article. Chelation therapy removes the lead from condors’ systems, but it requires capturing the birds.
Full Answer
Does chelation therapy really work?
But there's very little evidence it works for those conditions. In fact, chelation therapy can cause serious side effects -- including death -- especially if it's used in the wrong way. How Does It Work? Chelation therapy uses special drugs that bind to metals in your blood.
What is chelation therapy for lead toxicity?
When metals like lead, mercury, iron, and arsenic build up in your body, they can be toxic. Chelation therapy is a treatment that uses medicine to remove these metals so they don't make you sick.
How is chelation therapy used to remove heavy metals?
You get the chelating medicine through an intravenous (IV) tube in your arm. It’s also available in pill form. Once the drug has attached to the metal, your body removes them both through your pee. Metals that can be removed with chelation therapy include lead, mercury, and arsenic.
How does disodium EDTA work in chelation therapy?
The chelating drug disodium EDTA binds to this mineral. The idea is that chelation therapy clears it out of the blood vessels. It removes plaques, too. In 2002, the National Institutes of Health did a big study on chelation therapy, called TACT.
How do condors get lead poisoning?
Sources of Lead Exposure. California condors are obligate scavengers, and the principle source of lead exposure to condors is believed to be the ingestion of lead ammunition fragments embedded within carcasses of animals shot with lead ammunition (7).
What caused California condor decline?
According to the International Union for Conservation of Nature, the condor became critically endangered in the 20th century — one classification behind extinct in the wild. The decline came from poaching, habitat destruction and lead poisoning as condors scavenged for carrion containing lead shots.
How many California condors are left?
California condors have been out of Northern California's redwoods since 1892, according to a statement from the Yurok Tribe, California's largest Native American tribe. There are only around 200 adult California condors left in the wild, according to the International Union for the Conservation of Nature (IUCN).
Are condors extinct?
The California condor has been protected as an endangered species by federal law since 1967 and by California state law since 1971. In the 1970s, biologists found that only a few dozen condors remained in the wild. In 1980, a major conservation project was started to try to keep the birds from becoming extinct.
What is being done to save the California condor?
We are placing increased emphasis on captive-breeding to augment the wild population of California condors while working with the hunting and ranching community to reduce the threat of lead poisoning cause by spent ammunition, which is the primary cause of death in the wild and the biggest hurdle to sustainable wild ...
How can we help California condors?

What do conservationist currently doing with condors?
Today, over half of these birds are flying free at five wilderness release sites in California and Mexico. Our Recovery Ecology researchers work closely with Mexican partners to manage the California condor reintroduction program at the Sierra San Pedro Mártir Condor Field Station.
How many California condors left 2021?
TOTAL CAPTIVE POPULATION = 203.
What is the biggest threat to California condors?
lead poisoningThe biggest threat to condors today is lead poisoning. When a gun fires lead ammunition and it hits an animal, the soft metal breaks into many small fragments that spread beyond the wound channel. When scavengers such as condors feed on these remains, they inadvertently ingest the lead fragments.
How did scientists save the California condor from extinction?
In 1979, the U.S. Fish and Wildlife Service began the California Condor Recovery Program, and in 1987, when the population totaled a mere 27 condors, wildlife officials captured the surviving wild birds and made them part of an existing captive breeding program.
Are California condors hunted?
Condors are not hunted today, but they are susceptible to lead poisoning from bullets when they scavenge carcasses left by hunters. Pesticides also pose a threat to condors, as do powerlines.
Why are California condors important?
California condors provide a critical ecological service as scavengers: they only eat dead animals on the landscape. Like other North American vultures (or cathartids), condors are well-adapted for this purpose. They use their sharp, hooked beaks and powerful jaws and necks to yank, pull, and tear meat from carcasses.
When was the California condor put on the endangered species list?
The California condor was placed on the federal endangered species list in 1967. Critical habitat was identified and mortality factors were studied. The U.S. Fish and Wildlife Service began a captive breeding ...
What is the greatest threat to California condors?
Lead poisoning from ingesting fragments of lead ammunition in the carcasses and gut piles they feed on remains the greatest threat to California condors today. From the 1880s to 1924, there were scattered reports of condors in Arizona.
When did condors come back to the wild?
Best of all, captive bred condors were being released back into the wild in California beginning in January 1992. Today, more than 127 condors fly free in the state of California, from the Ventana wilderness and Pinnacles National Monument down to the Sespe Condor Refuge and Los Padres National Forest north of Los Angeles.
Where did condors live?
In Pleistocene times, condors ranged from Canada to Mexico, across the southern United States to Florida, and north on the east coast to New York. During that period, condors were a common resident of the Grand Canyon judging by bones, feathers and eggshells found in caves where they once nested.
When was the last condor captured?
A controversial decision was made to bring all remaining condors into captivity, and the last wild bird was captured on April 19, 1987 . All hope for recovery was now placed on the captive breeding program and the task was formidable.
How many condors are there in the world?
It was the first flight of California condors there since 1937. The world total of California condors today is around 400, more than half of which are in the wild.
