Peekaboo! Meet this cute and mega-rare baby kangaroo

This adorable animal has finally popped out of his mum's pouch to join a family of cuddly kangaroos at Chester Zoo.

Staff are always pleased to see baby kangaroos - called joeys - but especially when they're from a rare species whose numbers are low in the wild.

This new joey is a Goodfellow's tree kangaroo, a species native to the forests of Papua New Guinea that's listed as endangered.

This species is being cared for at just two zoos in the UK, and the team hope its birth can help the Goodfellow's tree kangaroos to bounce back in the wild.

You might think kangaroos can jump up pretty high, but Goodfellow's tree kangaroos also like to live very high up - you guessed it, in the trees.

Unlike other kangaroo species, they like to hang out on their own, and spend a lot of their time resting or sleeping in trees.

Goodfellow's tree joeys weigh between two to three grams at birth, and are about the size of a jellybean.

Once they're born, they climb from their mum's belly to the pouch, where they stay for around seven months to develop before popping their heads out.

And that's exactly what's happened at Chester Zoo, with kangaroo mum Kitawa and dad Kayjo welcoming their joey into the world.

The team at the zoo have followed the journey every step of the way, tracking the joey's development through a tiny camera in his mum's pouch.

Chester Zoo's tree kangaroo expert Matthew Lloyd says that using this kind of technology with the creatures "wasn't possible [until] only a few years ago."

"It's already helped us learn more crucial information about the early stages of life inside the pouch.

"With so little known about tree kangaroos, Kitawa's joey is a particularly special arrival."

And little is set in stone about Chester Zoo's special arrival too - including its name.

Matthew says: "We don't have a name for the little one just yet, but our choice will be influenced by communities in Papua New Guinea who live alongside tree kangaroos and are now part of efforts to protect their forest homes."

In those forests, Goodfellow's tree kangaroo numbers have dropped by half because of hunting and deforestation.

But Chester Zoo's team manager David White says: "Everything we've learned so far will help conservationists around the world in securing a future for this magnificent species."
