Zoo handlers cross fingers for a panda birth

LONDON — The British media are on baby watch again.

Tian Tian, the female panda at the Edinburgh Zoo, might be pregnant.

Her handlers can’t know for sure. But the black-andwhite crowd-pleaser is showing positive signs, like nesting behavior, and hormone levels in her urine are encouraging.

Any birth is likely to take place within the next two weeks.

A panda cub would be another boon to the zoo, which took delivery of Tian Tian and a male panda, Yang Guang, in December 2011 on a 10-year loan from China. They were shipped to the Scottish capital by FedEx in separate crates, each of which bore a label declaring its contents as: “One panda.”

The pair are now among the zoo’s top attractions, drawing visitors who coo over them on a strictly time-rationed basis put in place to manage the eager crowds.

Tian Tian was artificially inseminated with sperm from Yang Guang and also with samples taken from another male panda in Germany. Panda pregnancies are touch-and-go: Females can reabsorb their fetuses back into their bodies.

Tian Tian has given birth once before, in 2009, to twins, but the Edinburgh Zoo is taking no chances. Its panda handlers are on “red alert.” An expert— basically a panda midwife— has been flown over from China, and Tian Tian’s custodians can tune in to round-the-clock panda reality TV at home, with live footage of her inside her enclosure, to watch for signs of labor.

Tian Tian (“Sweetie” in Chinese) turned 10 on Saturday.
