Lead bullet ban to aid Condor recovery


The conservation of California Condor Gymnogyps californianus – one of America’s most high-profile reintroduction projects – has received a helping hand from a 270,000-acre ranch that is home to the state’s largest private hunting program.

Tejon Ranch Company, working with the U.S. Fish & Wildlife Service and Audubon California (BirdLife in the US) have announced they are to discontinue the use of lead hunting ammunition on their privately-owned ranch in California’s Tehachapi Mountains.

California Condor has declined rapidly throughout the 20th century, so much so that in 1987 the species became extinct in the wild when the last six wild individuals were captured to join a captive-breeding recovery programme.

Conservationists have attributed this drastic population decline principally to persecution and accidental lead ingestion from shot carcasses.

Today the wild population numbers some 70 reintroduced individuals.

    California Condor lays egg in Mexico

    Associated Press Writer

    SAN DIEGO (AP) — An egg found in an abandoned eagle nest could herald the return of the California condor to Mexico, which hasn’t had a breeding population of the iconic giant of the skies for about 75 years.

    “This is a momentous occasion,” Dr. Mike Wallace of the Zoological Society of San Diego said Monday. “We’re all excited.”

    The California condor, once on the brink of extinction, is the largest bird in North America with a wingspan of almost 10 feet.

    Wallace and colleagues found the egg March 25 on a cliff in the Sierra San Pedro de Martir National Park, located in the arid interior of the Baja California peninsula more than 100 miles south of the U.S.-Mexico border.

    Wallace climbed to the nest and took photographs and measurements of the egg, shining a bright light through the shell to determine that the egg was 45 to 50 days old. Condor eggs incubate for 57 days, meaning the chick could hatch any day. There was also a chance the egg was dead, but Wallace said he did not smell any sulfur and the parent condors were still tending to it.

    “We are all sitting on pins and needles waiting to see where the situation is going,” said Wallace, who works for the zoological society’s center for Conservation and Research for Endangered Species. The society also runs the San Diego Zoo and its wild animal park.

    The California condor was once widespread, swooping above the western United States, parts of Canada and Baja California.

    A type of vulture, the condor scavenges dead fish and animals. As coastal population of seals and otters declined, so too did the bird. The use of poison to kill California’s grizzly bears in the 1800s also devastated their numbers and lead shot remains a potential source of poison. Hunting, egg collecting and power cables were also blamed for hurting the creature’s numbers.

    Only 22 California condors were left by the 1980s, and the last documented sighting in Mexico was in the 1930s, Wallace said.

    Thanks to a captive-breeding program, numbers recovered to a worldwide total of about 280. More than 100 of these fly free in the skies above parts of California, Nevada and Utah. Working with the Mexican government, biologists reintroduced captive-bred birds to Mexico in 2002.

    Condors don’t reproduce until they are several years old, Wallace said. The 7-year-old female that laid the egg in Mexico, known as Condor 217, was born at the Los Angeles Zoo.

    Another species of condor, found in the Andes, is also threatened with extinction, but its numbers are in the thousands, Wallace said.

    Several organizations have been working together to boost condor numbers under the Condor Recovery Program, which was founded in 1982 by the U.S. Fish and Wildlife Service. Among them are several Mexican groups, the Los Angeles Zoo, Peregrine Fund’s World Center for Birds of Prey and Oregon Zoo.
