Absolutely nobody's babies are safe when Lefties get involved. In California, fer sure. In San Francisco, of course. This is what Lefties believe; the state always knows better than the parents.
Peregrine falcons construct their nests in precarious places on purpose. They generally choose a wind-swept cliff face. I once visited a friend of mine in Colorado who had volunteered to feed peregrine falcon chicks being raised on a cliff face in order to help re-populate a then precarious low population of peregrines in the area. The cliff was no less dangerous or windy than a bridge, and the babies did fine. Mark, correct me if I'm wrong, but all the babies hatched and all of them fledged and flew off by themselves. That the folks in San Francisco believe they can raise peregrine falcon babies better than the parents (who, by the way, have been successful in raising their young for years) is fully in compliance with Lefty doctrine. Lefties believe they are better humans than the average human, and they also believe they are better peregrine falcons than the aaverage peregrine falcon.
There's no limit to the ego of the average Leftie, and neither man nor beast is safe from their stupidity.
