Snakes, bobcats, mountain lions: the secret animal world beneath the Hollywood sign

An international symbol for the city, the sign is also hallmark of the region's environmental richness

Atop Mount Lee, in the heart of Los Angeles, the wind is quiet. Two red-tailed hawks sail above, barely flapping as they coast the thermal air like surfers on a wave. Standing beside the giant letters of the Hollywood sign, the city seems peaceful. On a clear day, blocks and blocks of homes unfold beneath and the skies reveal sights all the way to Catalina Island - 10 miles out, across the Pacific.

That's the beauty seen from the Hollywood sign.
