World's rarest chimpanzee born at UK zoo

STORY: The male chimpanzee, who has not been named yet, was born on December 9th to mother ZeeZee, whom he has been bonding with amongst the other 22 chimpanzees at the zoo.

The population of the Western chimpanzee has dropped by 80% in the last 25 years and so the arrival offers hope for the survival of this particular species, experts at the zoo said.
