If countless newspaper articles and frantic local TV coverage still haven't quenched your thirst for Tai Shan, Animal Planet delivers yet another hour of panda pandering tonight.

For those who can't get enough, "A Panda Is Born," a one-hour documentary airing at 8, nicely chronicles the National Zoo's five-year mission, and eventual success, for a panda birth.

For the rest, it's worth taking a look if only for one snippet of grainy black-and-white footage from the network's "Panda Cam" that captured Butterstick's birth.

Here's what we get to see: Tai Shan, no bigger than (here's that analogy again) a stick of butter, splooshes out of mother Mei Xiang as if he's been fired from a cannon, hits a nearby wall and lands flat on the ground. The scene is shocking and, for a second, it looks as if he might not have survived the violent entry into the world. But soon the little guy starts squealing like a stuck pig and we know all is well.

It's quite a moment, and Animal Planet claims it has yet to be seen on television.

The rest of the documentary is an adequate history lesson that explores Washington's fascination with pandas, going back to 1972, when Ling Ling and Hsing Hsing came to the National Zoo. We see a beaming Pat Nixon hoping the pandas will reproduce.

At times, "Panda" comes across as an infomercial for the zoo, which is not surprising considering that Animal Planet is the zoo's exclusive media sponsor and has contributed millions of dollars to the zoo.

The documentary includes comments by former zoo director Lucy Spelman -- no mention is made of her unceremonious exit -- and details her trip last year to China to better understand panda mating habits. The network praises the zoo throughout, especially when explaining that the zoo has had successful tiger and elephant births.

Some scenes with zoo employees hovering over monitors to check out the two pandas during mating season -- will they or won't they? -- come across humorously, if not a bit creepy. "She's backing into him with her tail raised," panda keeper Laurie Perry says. "Just another sign that she's interested in him."

In footage from last year, after the two pandas fail to even go through the motions of mating, assistant curator Lisa Stevens seems disappointed. "Last year, we got 15 seconds. This year, we got nothing," she says. There's also fascinating video of the artificial insemination.

But we come for adorable shots of Tai Shan, and adorable shots we get. There's plenty of video of the cub being poked, prodded and picked up by staffers who "ooh" and "aah" over his every move.

Chances are, you'll be oohing and aahing yourself.

A Panda Is Born (one hour) airs at 8 tonight on Animal Planet.
