A Bolivian squirrel monkeys plays with a pair of sunglasses smeared with bitter apple to train him not to steal visitors’ sunglasses, at ZSL London Zoo, in London, on April 7, 2011. Zoo keepers have discovered Bolivian squirrel monkeys stealing visitors’ sunglasses since the sun came out last week. The group of 18, who live in a no barrier enclosure, have been given sunglasses with bitter apple smeared on them today in a bid to stop them from being so light-fingered this summer.
