For the second time in two days, one of the rare California condors at the Los Angeles Zoo has laid an egg for the breeding program aimed at saving the endangered species.

Keepers removed the egg from the nesting box of Cuyama and Cachuma early Thursday without disturbing the birds. Removing one egg from the nest usually induces the birds to lay a second.If all goes well, the egg should hatch in April, zoo officials said.

Two condors named Anyapa and Kaweah laid an egg on Tuesday.

All 40 known California condors are kept either at the Los Angeles Zoo or the San Diego Wild Animal Park, which are working to breed larger flocks.
