And Imissed it by only about an hour, too:

The ostrich, a female, got loose around 4:45 p.m. from the rear of the northbound van, which was heading for a Healdsburg vegetable farm, said California Highway Patrol sergeant Wayne Ziese. A sudden acceleration of the van caused the bird to smash through the rear window and land on the bridge pavement, just north of the [Golden Gate] toll plaza.

“It should never have happened,” said the driver of the van, Ronald Love. “The ostrich’s butt broke the window. You never would think an ostrich could fit through a little window, but she did.”

I dunno – they look like pretty bendy birds to me . . . .
