From the BBC:
A rare Mexican bird that died out in the wild in the 1970s has been successfully bred at London Zoo.
The Socorro dove is native to Socorro Island in the Revillagigedo Islands, 600 miles off the west coast of Mexico.
The species was last sighted in Socorro in 1972 and there are now thought to be fewer than 100 in captivity.
Zoo keepers have named the new dove, Arnie – after Arnold Schwarzenegger.
