One of North America's rarest birds has fought back from the brink of extinction and is enjoying a renaissance - on a rocky outcrop used by the US Navy as a firing range.
The San Clemente Island loggerhead shrike is thriving on the rocky outcrop off the Californian coast, known as the 'boom box'.
In the 90s its numbers had dwindled to just seven breeding pairs, but now there are believed to be 70 on the island.
It is a remarkable success story given the black, grey and white songbird shares its home with an area that is regularly bombed by US Navy battleships.
The Navy itself has claimed credit for the shrikes survival after it launched a $3-million-a-year captive breeding programme to protect the threatened species, according to a report in the Telegraph.
