Dolly hatched in the wild at Pinnacles National Monument from an egg that was laid at the Oregon Zoo. After her fourth health check in the field, at the age of 120 days, she was observed unable to use her right wing due to a fracture near the shoulder. L.A. Zoo veterinarian and orthopedic surgeon Dr. Stephen Klause performed two surgeries to try to repair it, but the break was too high on the upper wing bone (humerus). As a result, the bone would never be stable enough to support flight. The injury precludes her from being housed in a large flight aviary because she might climb to a high perch and be injured attempting to fly from it. Also, keeping her with other birds is risky. Condors can be competitive and antagonistic toward each other, and a bird who cannot escape more aggressive personalities is in danger of being injured. So, the idea was hatched for her to become an ambassador animal—a first for her species—and she has excelled at making connections with people on behalf of California condors everywhere.
The field health checks and veterinary care that Dolly received were part of the California Condor Recovery Program, a collaborative effort between the L.A. Zoo and a host of partner organizations, including the U.S. Fish & Wildlife Service, U.S. Forest Service, National Park Service, Bureau of Land Management, Arizona Game and Fish Department, California Department of Fish and Wildlife, Utah Department of Fish and Wildlife, the federal government of Mexico, the Yurok Tribe, San Diego Zoo, Oregon Zoo, Santa Barbara Zoo, Chapultepec Zoo, the Peregrine Fund, and the Ventana Wildlife Society. This vital, necessary work has brought the California condor back from the edge of extinction, from just 22 individuals remaining in the wild to a total population of more than 400 and counting.
Another vulture you’ll spot in the World of Birds Show is Mort, a northern black vulture. Black vultures and turkey vultures are the most common vultures in North America. Both are large birds with wingspans of five to six feet, but that’s only about half the size of North America’s largest flying bird: the California condor.
