The zoo, which regularly surprises its animals with festive and enrichment-themed presents to develop behaviourial and natural skills, treated the chimpanzees with gift-wrapped food treats and a collection of gingerbread houses for the lemurs.

“While Christmas only comes once a year, enrichment is something we incorporate into the lives of our remarkable animals every day,” says primate keeper Ben McDonogh. “These enrichment items are a fun surprise, but they also provide the chimps with opportunities to showcase the skills they have developed to be successful survivors in the wild.”
