SAN JOSECITO, COSTA RICA: Hanging out: Zoologist Lucy Cooke holds a cute baby sloth A GROUP of doe-eyed sloths learn to climb by scaling and then swinging from the back of a rocking chair. Shot in May, this adorable footage was filmed by zoologist and broadcaster Lucy Cooke during a visit to the Toucan Rescue Ranch in Costa Rica. The wildlife rehabilitation centre uses a rocking chair to help teach the orphaned baby sloths how to climb – as the swaying motion is similar to a tree. Lucy, who has been called the ‘Spielberg' of sloth documentaries, has released a calendar dedicated to the super cute mammals.s713
