It isn't very clear because I only had a 35mm lens with me, but if you open the photo to full size you might be able to see a new baby (about a week old as of when the photo was taken) clinging to the female on the right of the photo. The male is the one walking below in an upright stance.
@Chlidonias Nice photo! The male walking is Aranyo (born 2016 at Hamilton Zoo). It’s nice to see he’s successfully bred with at least one of the females, following his transfer from Hamilton Zoo. This would be Wellington’s first infant in over a decade.
@Chlidonias Wow, I had wondered if any of the zoo’s younger females had been born there, but they were obviously transferred in or imported from overseas. I recall multiple species being represented in Wellington’s troop, so I assume they didn’t breed so as not to hybridise.
