The California condor, the slightly smaller of the two types of condors, is native to the coastal mountains at the southern end of the San Joaquin Valley. They usually feed on dead animals, but also have been known to attack live prey. Once fairly abundant, California condors now are endangered species. Many were hunted, while others were killed by eating poisoned carcasses of wolves and coyotes that were set out by farmers. Condors only lay one or two eggs per year, keeping their population growth slowed. A consortium of federal, state, and private organizations in 1979 initiated a rescue program that involved taking eggs from nests in the wild and incubating and breeding the young birds.
