A zoo is celebrating an alternative Mother's Day this year after one of its residents gave birth.

Izzy the coppery titi monkey has been at Banham Zoo since 2013 and she has just given birth to her fourth baby.

A spokesman said: 'If there was an award for best mother this Mothering Sunday, keepers at Banham Zoo would certainly be thinking of putting Izzy up for the accolade.'

The infant monkey is living with its mother in the Eureka enclusre at the zoo with Izzy's mate, Juanito, and their three previous offspring, Julio, Maitae and Zaria.

Coppery titi monkeys are native to South America, specifically Brazil and Peru, and are not threatened in the wild due to their remote and isolated natural habitat.

The infants cling to their parents' backs so it can be difficult to spot a newborn however the zoo always has keepers and volunteers on hand to help visitors spot the new arrival.
