All eyes on Britain's panda pair as mating season approaches

Experts at Edinburgh Zoo in Scotland have begun daily check-ups of Britain's only female giant panda Tian Tian and male partner, Yang Guang, the zoo announced on Monday.

The is hoping to put behind the disappointment of last year, when Tian Tian suffered a late-term miscarriage after being artificially inseminated, and is looking out for signs that the pair are ready to mate.

"Tian Tian and Yang Guang are both in great health and condition and things are progressing nicely," explained Iain Valentine from the Royal Zoological Society of Scotland (RZSS), which runs the zoo.

"The are clearly showing an increased interest in one another, both pandas are fairly regularly scent marking now and we've also seen food intake increase in both pandas as they seek to drive their body weight up—all fantastic instinctive pre-breeding behaviours.

"Similar to last year, alongside our own experts, RZSS is working together with a number of global colleagues on the complex science that goes on behind the scenes. Natural mating will be attempted, likely followed by artificial insemination as recommended by our Chinese colleagues," he added.

The zoo acquired Tian Tian, whose name means Sweetie, and Yang Guang (Sunshine) from China in December 2011 but the pair have so far failed to mate.

Tian Tian was artificially inseminated in April last year, but the zoo announced she had lost her cub in October.

Pandas, whose natural habitat lies in mountainous southwestern China, have a notoriously low reproductive rate and are under pressure from factors such as habitat loss. China has about 1,600 living in the wild.

Their normal breeding season is mid-April to May.

It's not Britain's panda. China claims ownership of all Giant Pandas in the world. The Edinburgh Zoo may be paying something like $1 million per year to rent this panda ambassador.

With a nod to China's tepid enforcement of IP laws, it would be interesting if, in the near future as we gain the capability, someone were to copy the genome and build a panda clone from scratch. A panda line not owned by China. Bonus points if we can tweak its fertility.
