Zookeepers in Victoria, Australia, celebrated in September when an newly-born endangered Goodfellow’s tree kangaroo appeared out of its mother’s pouch for the first time at Healesville Sanctuary.Mum Mani and dad Bagam were successfully paired in 2016, and the tiny, jellybean-sized joey was discovered inside Mani’s pouch earlier this year. It was the first Goodfellow’s tree-kangaroo to be born at the sanctuary, officials said.After six months staying warm and cosy inside the pouch, the little one peeped his head out in September to say hello. Zookeepers said the joey will venture out more and more over the coming months as it learns more from mum and dad.Tree kangaroos live in the wild in rainforests across Papua New Guinea, Indonesia, and far north Queensland, but all populations are in decline. The tree kangaroo family at Healesville Sanctuary are part of Zoos Victoria’s efforts to fight against extinction. Credit: Healesville Sanctuary / Zoos Victoria via Storyful
