A seriously ugly bird, but it is great they are flourishing, as this story from Associated Press reports.
BIG SUR, Calif. (AP) — In a remote, rugged valley overlooking the Pacific Ocean, researchers closely monitor an endangered icon: the California condor.
The giant vultures flap their wings and circle the sky before perching on branches and observing their observers. Wildlife biologist Amy List uses a handheld antenna to track the birds, which wear radio transmitters and numbered tags.
“If we don’t know what they’re doing, we don’t know what’s going wrong,” said List, who works for the Ventana Wildlife Society, which manages the condor sanctuary in Big Sur.
Three decades after being pushed to the brink of extinction, the California condor is making a comeback in the wild, but constant vigilance is needed to ensure the endangered bird doesn’t reverse course.
One of the world’s largest birds with a wingspan up to 10 feet, the condor once patrolled the sky from Mexico to British Columbia. But its population plummeted in the 20th century due to lead poisoning, hunting and habitat destruction.
In 1987, wildlife officials captured the last remaining 22 condors and took them to the San Diego and Los Angeles zoos to be protected and bred in captivity.
Those efforts have led to a slow but steady recovery for a species that reproduces slowly compared with other birds. There are now roughly 450 condors, including about 270 in the wild in California, Arizona, Utah and northeastern Mexico.
Plans also are underway to release some captive-bred condors in Redwood National Park in 2019 to establish a population near the California-Oregon border.
Federal officials said in August that for the first time in nearly 40 years, condors were roosting in the Blue Ridge National Wildlife Refuge, expanding to their historical range in the southern Sierra Nevada.
Another milestone was reached this summer: the first “third generation” condor was born in the wild in California since the 1980s.
“We’re seeing very encouraging results that the condors can become self-sustaining again,” said Kelly Sorenson, who heads the conservation group.
While condors still face threats from exposure to mercury and the pesticide DDT, biologists say the biggest danger is lead ammunition, which can poison the scavengers when they eat dead animals shot with lead bullets. California banned the use of lead ammunition near condor feeding grounds in 2008 and will be the first state to ban lead bullets in all hunting in 2019.
