A one-month-old baby Siamang Gibbon sits with its mother Salome as they shelter from the wind and the rain in their enclosure at Noahs Ark Zoo Farm on February 1, 2011 in Bristol, England. The little ape, yet to be named, is a Siamang Gibbon, which are facing worrying population declines, with zoos playing an important role in maintaining healthy populations in captive environments. His parents, Samson and Salome are part of a European Endangered Species Programme (EEP) for managed breeding and have a 1-year-old sibling called Sultana who was also born in captivity.
