Today's the day the teddy bears have their picnic

Or at least a romp in the grass.

Everything was on the table -- more accurately, on a video projector -- at Miami Metrozoo's Sex and the Animals event, a Valentine's Day tradition.

Hosted by zoo ambassador Ron Magill, the popular lecture attracted more than 400 people to see and hear the intimate details of how wild things do the wild thing.

"This is the fifth time in a row this thing has sold out," Magill said. "And I'll tell you why -- everybody wants to hear about sex."

...

He clicked through dozens of images -- all photos he shot on African safaris and other excursions -- of animals in the act.

"I got right down on my back for this one," he said of a few close-ups.

Magill dropped plenty of nuggets of who-knew? information, such as:

• Flamingos like to have sex with others watching them. Two of the birds will get down while 30 others look on.
• Frogs sometimes do it with two or more partners at a time. Most animals are not monogamous, Magill said.
• Female pandas only have a three-day window each year to get pregnant. Zookeepers have shown the pandas films of other pandas having sex to get them in the mood.
• Tigers in captivity are implanted with birth-control devices so they don't over-reproduce.
• Some animals are gay, too. "Homosexuality is found throughout the animal kingdom," Magill said.

Biological exuberance in action!
