EDINBURGH Zoo’s female panda is pregnant and could give birth tomorrow (fri), it was confirmed today.
Tian Tian is set to give birth to the UK’s first panda cub six years after arriving in Scotland and after five failed previous attempts.
A spokeswoman for the zoo said: “Giant panda breeding is a very complicated process but we believe that Tian Tian is pregnant.
“Although a specific date was suggested, like all babies, it’s hard to predict precisely and the panda breeding season can last until late September.
“Tian Tian is being closely monitored by our expert team and we will be the first to share any news as soon as we can.”
Scottish Government officials and staff at the zoo discussed in late July that Tian Tian was definitely pregnant and put her expected date as August 25.
Tian Tian, who arrived in Scotland as part of breeding pair with Yang Guang in 2011, was artificially inseminated for the fifth time late last year.
The decision to go ahead with artificial insemination came after the zoo decided there was now no prospect of Tian Tian and Yang Guang ever mating naturally.
Documents released under Freedom of Information today (THUR), show that in late July this year Tian Tian’s pregnancy was “on track” and the mother-to-be is “doing real well”.
An email, dated July 25 2017, from Iain Valentine, director of giant pandas at the Royal Zoological Society of Scotland (RZSS), to the Scottish Government, stated: “‘TT doing real well. As things are at the moment, she seems on track but I have shifted possible birth date to around 25th August.
“Will be able to be a bit more precise in a week’s time.
“So she is about 30 days out now and pregnancy proper has now begun in what we think is a 37 day pregnancy. See or hear from you soon. My best, Iain.’”
The email that prompted the revelation was sent earlier that day from the Scottish Government reading: “I was reminded that this is the season when we might be expecting some baby pandas and I know [Scottish Government Official] has been in touch with you about the progress there.”
A previous email from Iain Valentine, dated July 10, 2017 read: “All seems fine with TT at the moment…waiting on results from last set of samples so will see what they turn up.”
An email from a Scottish Government official, dated July 4, revealed how excited they were over the zoos potential new resident, stating: “Thanks for the update – exciting times (we hope).”
An earlier email from Mr Valentine, dated June 29 2017 read: “Tian Tian is doing just fine and latest sample results are showing that things are on track at the moment.
“It’s a bit early to give a potential birth date if there is to be a birth, a good window of opportunity to look to is from the end of July to mid August.
“I will be able to home in on a potential date a bit better in about ten or so days time when another set of tests kick in. Will keep you posted on TT as things move forward.”
The two giant pandas arrived in Scotland in December 2011 and are rented by Edinburgh Zoo from the Chinese government for ten years, costing an annual fee of around £600,000.
Panda experts at Edinburgh Zoo carried out the artificial insemination late last year after hormone monitoring revealed that Tian Tian hit peak oestrus levels.
It was the fifth time Tian Tian has been artificially inseminated and the move sparked renewed criticism from animal rights campaigners who accused the zoo of being more focussed on making money than the panda’s welfare.
Tian Tian had previously given birth to twins in China but all previous attempts to produce a cub at Edinburgh Zoo have failed.
Zoo staff have said in the past that she may have been pregnant on a number of occasions.
However pandas can sometimes re-absorb the foetus during the course of the pregnancy.
In 2014, panda expert Gareth Starbuck said the panda enclosure is unsuitable for breeding and described the £275,000 enclosure as “sparse, has a lot of concrete, one token tree and no cover”.
Last week, scandal hit Edinburgh Zoo when a former zoo keeper at the company revealed how a Yang Guang was let into his enclosure by mistake while a keeper was still inside.
Both Edinburgh Zoo pandas were born in 2003 and lived at the Ya’an reserve in Chengdu, China.
Tian Tian, whose name means “sweetie”, and Yang Guang, meaning “sunlight”, travelled from China on board a Boeing 777F flight dubbed the FedEx “Panda Express”.
The were the first pair of giant pandas to live in the UK for 17 years and are part of a ten year breeding scheme with China.
Officials hope their presence will boost tourism and the Scottish economy with animal lovers flocking from across the UK, and world, to see them.
The exciting news comes on the same day that Tian Tian celebrated her 14th birthday.
Panda experts at Edinburgh Zoo began monitoring her hormone levels in December and artificially inseminated Tian Tian when she hit peak oestrus levels.
Writing in his blog in May, Iain Valentine revealed: “We began hormone monitoring in December last year and as of 17/18 March Tian Tian hit peak oestrus, the earliest this has happened over the past six years and fully a month and a half earlier than last year.”
In 2013, zoo bosses revealed how hormonal and behavioural signs had indicated that Tian Tian conceived, carried a foetus but sadly lost it, late term.
