This is Laa Laa, the Francois Langur monkey
Although a bright orangey-red colour when she is young, the monkey's fur will turn black as she matures.  The baby monkey will only keep her bright ginger fur for up to six months before it turns to her adult darker colour.

The bright coloured fur of the young f this breed of Monkey helps her mother keep a close eye on her as she is easily spotted among the dense greens of the Jungle.

In honour of the arrival of a rare red head at London Zoo, humans with the same hair colour are being given cut price entry to the venue on Sunday as red heads can visit the central London zoo with a friend with any hair colour on a two-for-one basis.
