The Pitter-Patter Of Little... Paws?

You know that old saying, I wouldn't, blah, blah, blah, even if you were the last guy on earth? Well, what if you pretty much were the last guy on earth? Only about 2,500 giant pandas remain in the wild so zoos are trying to get these animals to breed in captivity. The Smithsonian's National Zoo has two giant pandas, one female and one male. Now, when it comes to panda mating, attraction is key.

But it turns out, it isn't quite enough. Sabri Ben-Achour headed over to the zoo to see how the pandas are performing.

MR. SABRI BEN-ACHOUR

13:26:56
Step into the panda center at Smithsonian's National Zoo and you'll see a wall of computer screens.

MR. DAVID MCKEE

13:27:01
If the big event happens, we will have cameras.

BEN-ACHOUR

13:27:05
David McKee is a volunteer at the zoo and the big event, televised live over the web, is panda mating. Panda's Mei Xiang, that's the female, and Tien Tien, that's the male, are on loan to the U.S. from China. They are here for several reasons, to help China-American relations, to learn more about the species, but really the main reason is to get these two bears to reproduce. So when mating season comes around, all eyes are on the pandas.

MS. BRANDIE SMITH

13:27:30
People are sleeping here at the Panda House and we are monitoring those pandas 24 hours a day.

BEN-ACHOUR

13:27:36
Brandy Smith is a senior curator at the National Zoo. She says they have to watch these two pandas because, basically, they're really bad at getting intimate. Like, really, they are terrible.

SMITH

13:27:45
Our pandas are rather interesting. They can't quite get the positions right. So Mei Xiang -- we call it pancaking. She kind of lies flat on the floor instead of having her posterior up in the air and a male, who was very experienced we would hope, would come in and he would kind of lift her up to get her in the right position. Tien Tien doesn't do that very well. And instead Tien Tien comes over and he actually kind of steps on her so he helps kind of keep her in that pancake position. And then, as you might imagine, attempts at breeding with him just stepping on her, aren't really that successful.

BEN-ACHOUR

13:28:22
In the wild, Smith says, other pandas can teach Tien Tien and Mei Xiang how not to screw everything up, if you will. But they don't have that here. So the zoo keepers let the pandas try it on their own and when they inevitably fail because they're so terrible, the keepers step in and use artificial insemination. But they only have one shot because Mei Xiang is really just not into it very often. They can only, like, do it once a year?

SMITH

13:28:46
Yes, the panda breeding season -- it's an annual breeding season, one time a year. And it's very brief. So for our pandas it's a day a year.

BEN-ACHOUR

13:28:56
So to figure out when that one day is coming near and to make sure they have all the artificial insemination equipment at the ready, the keepers have to watch, constantly. Smith holds up a map.

SMITH

13:29:06
So this is actually a urine map of the panda habitat. So during the breeding season, every time Mei Xiang pees, we collect it.

BEN-ACHOUR

13:29:14
They analyze the urine for changes in hormones to know when Mei Xiang's day is coming. Tien Tien is very interested as well.

SMITH

13:29:19
He's smelling her. He actually tastes her urine to evaluate the hormones that are in there. We look at urine to see the hormones and when she's ready for breeding. Tien's incredibly sensitive and he knows exactly that moment in time when she should be bred.

BEN-ACHOUR

13:29:33
And finally, the big day arrives.

SMITH

13:29:35
The female panda has certain behaviors that occur, no other time during the year except for that day when she bleats, kind of makes noise that says that she's in the mood. One of my favorite is that she'll lift up her tail and she walks backwards showing the male panda that she's ready and letting them know that she's available.

BEN-ACHOUR

13:29:53
So after the pandas fail miserably at sex and the zookeepers have to step in and take charge, things go pretty much back to normal. The volunteers go home, nobody sleeps at the zoo, but it's not over. It'll take four to six months for them to know if Mei Xiang's actually pregnant.

SMITH

13:30:06
Giant pandas go through either a pregnancy or a pseudo pregnancy. So the physiological changes her body goes through and the behavioral changes that she goes through, are exactly the same whether she's actually pregnant or just going through a pseudo pregnancy.

BEN-ACHOUR

13:30:21
So far, only one cub has been born at the zoo, Tai Shan in 2005. And now that's he back in China, the keepers are quite eager to once again hear the pitter patter of little paws. I'm Sabri Ben-Achour.
