After being separated for 3 years, 13-year old Silverback gorilla Kesho was reunited with his 9-year old brother Alf. And their joy of being reunited was immediately apparent:
Longleat [Safari Park] keeper, Mark Tye, said: "The keepers from Dublin weren't entirely sure the brothers would even know each other, but the moment they met you could just see the recognition in their eyes."
Conservationist and chairman of the APE Alliance Ian Redmond, remarked:
"What you're seeing is exactly what you think you're seeing," he said. "Two intelligent social mammals, who were separate, are pleased to see each other again and play together. It is gorilla joy, being reunited with someone you used to have good times with and now you can again, so it's gorilla happiness"
They're not so different from us, after all! The BBC has the slideshow: Link
