A wildlife park in Kent is gearing up for the arrival of two new giraffe calves, and broadcasting it online.

The pregnant females Lunar and Lehana arrived at Port Lympne Reserve in 2013 as part of a breeding programme.

It was designed to boost dwindling Rothschild giraffe numbers in the wild, where they are an endangered species.

The pair have already had successful births before, and are now in the final stages of pregnancy.

The wildlife park Facebook page said: "Lunar is now very close to giving birth and is showing all the usual pre-labour behaviours, so every night from now will be shut in by herself in preparation for this big moment."

They posted on their live Youtube video, saying: "We are awaiting the arrival of two new little calves and we want you to join us on this incredible journey!

"Please help to spread the word, and share this far and wide so hopefully, many of you will be able to witness a live giraffe birth!"

The live stream began on Monday, but viewers could be waiting some time for the big day.

Animal Director, Simon Jeffery said: "We are delighted that our two female giraffe, Lehana and Lunar are both expecting again and we wanted to share this incredible journey with everyone far and wide.

"This is a really exciting time for us and based on the comments and shares we have already received, people are really pleased that we are sharing this with them.

"It’s fantastic that giraffe fans, not just in the UK, but from all around the world are joining in too!

"I must admit it’s very addictive to watch and I can’t wait until the calves are born."

The video says: "Both pregnant females are seven years old and due to give birth in the next few weeks.

"Lunar should give birth first. She is mum to two year old female Mwezi.

"Lehana is due to give birth shortly after Lunar and is mum to two year old male Bakora.

"Father to both the youngsters and our imminent arrivals, is the aptly named Valentino.

"They are all Rothschild giraffe, endangered in the wild, it is estimated that there are only around 1,600 left in the wild. They all live on our reserve along with three hybrid giraffe males, Cillian, Settanta and Sebastian."

Lunar's calf was the first giraffe to be born at the reserve near Hythe in eight years when she arrived in 2016, and Lehana's calf arrived the following December.

The eight giraffes have nearly 100 acres of land in the daytime just outside of Hythe as part of the centre's African experience.

They spend their nights in a heated indoor enclosure.

Tips on how to spot the difference were also given on the video: "It can be tricky to tell the giraffe apart on Giraffe Cam but Lunar is slightly shorter with black tips on her ossicones (horn-like features) and a longer tail.

"Lehana is the tallest of the four you will see on the giraffe cam, and her ossicones are not straight, one goes back and one goes forward and her tail is shorter."
