However, due to the extremely low population and high levels of predation, it is supplemented with additional young birds, adult pairs and pairs with offspring, which have been released from the captive breeding program coordinated by the U.S. Navy, San Diego Zoo Wildlife Alliance and the Institute for Wildlife Studies.
