Beautiful moment orangutan introduces newborn baby to older son

An orangutan carried her newborn baby up to a nearby window to introduce it to her other son.

Rudy, a 36-year-old Bornean orangutan, gave birth to the infant at The Topeka Zoo and Conservation Center in Kansas on May 7.

Bornean orangutans are critically endangered and in the wild are only on the island of Borneo in southeast Asia.

After the birth, the enclosure was closed to allow for private bonding time between Rudy and her newborn daughter.

In the video, Rudy can be seen carefully carrying the newborn over her shoulder to the window of her enclosure.

The mum then settled down with a handful of fresh lettuce before another one of her other offspring, Bumi, born in 2013, approached the other side of the glass.

Bumi then presses himself up against the window, eager to get a glimpse of his baby sister who was born just moments before.

Both the infant and Rudy are healthy and doing well, and are now able to be viewed by the public.
