I finally got a chance to trek out to Eastern Hills to see The Wild Parrots of Telegraph Hill. This lovely documentary about "dharma bum" Mark Bittner and the wild cherry head conures he befriended above North Beach inspires and warms. (I'll be reading his book, next.)
I saw the flock, myself, one day in Washington Square Park, and it's one of my best memories of San Francisco.
See the film if you can.
