QUEST meets the San Francisco Zoo’s resident peregrine falcon, "Bella." Not long ago Peregrine Falcons were perched at the edge of extinction. But through the work of conservationists, they have rebounded and have been taken off the endangered species list. "This is a conservation success story." says Noelle Bidegainberry of the SF Zoo, "Our hope is that when people meet Bella they are inspired to take conservation into their own hands."
