Zoo-keepers at Edinburgh Zoo have expressed surprise at how quickly their most sociable animals and birds have taken to snapping selfies.

Cameras were placed in enclosures in the hope that spontaneous moments would be captured, and the creatures left to their own devices.

Jon-Paul Orsi, Digital Manager for the Royal Zoological Society of Scotland, commented: "We do a lot of our own photography on-site and these shots offer something completely different - the animals showing off their true personalities.

"We were surprised by how much they enjoyed being in front of the camera, particularly with one of our resident koalas hogging the limelight."

Ben Walsh from HTC, who provided the cameras, commented: "We know the most popular thing on the internet is funny pictures that owners take of their pets so at HTC were glad we've made a camera so brilliant and simple that animals can finally join us humans and start taking selfies too.

"With koalas taking the most pictures of themselves, expect to see their Instagram feeds full of koala selfies."
