SAN DIEGO (AP) – The San Diego Zoo says a rare California condor chick has hatched on a rocky cliff in Baja California.

The zoo announced the hatching Thursday. It’s only the second time a condor chick has hatched in Mexico since the zoo reintroduced the critically endangered species to the area in 2002.

The other hatched in 2007, but disappeared a month later.

Zoo officials say the latest chick has been immunized against West Nile virus, after biologists rappelled 330 feet down the cliff to get to its nest. The condor is in Baja’s Sierra San Pedro de Martir National Park, and officials say it is about 45 days old.

The birds are being reintroduced by the California Condor Recovery Program, an organization comprising zoos and government agencies from the U.S. and Mexico.
