A California condor has died of West Nile virus, officials said Tuesday, confirming a new threat to the government's 20-year effort to restore the high-soaring vultures to the wild.
"If even a couple of birds are hit by the virus, it is serious because it's such a small population," he said
Just two or three chicks are hatched each year in Ventura County's backcountry, Grantham said. Though the birds are constantly monitored with remote cameras, getting to them can involve a helicopter ride and a strenuous hike, Grantham said, adding that the effort is well worth it.
Condors are now breeding in the wild again, though the program continues to suffer setbacks from chicks that ingest trash, glass, antifreeze and a variety of other things.
