Take a stroll in Golden Gate Park at dusk and if you’re lucky, you’ll hear a sound perhaps unexpected: the hooting of wild owls. Jessie Bushell of the San Francisco Zoo debunks some common myths about owls while introducing us to several rescued owls currently living at the zoo—from a 3-ounce northern saw-whet owl that was hit by a snowmobile to a 10-pound Eurasian eagle owl confiscated from a smuggler.
