The film's endearing guide is Mark Bittner, an aging bohemian, but the supporting cast members, a rambunctious flock of urban parrots, are the true stars, and their surprisingly humanlike behavior makes for a wondrous and rare experience. The film follows the ups-and-downs of these wild birds within the green niches of San Francisco as Bittner befriends, feeds, and names the members of the flock. Along the way, we meet many unforgettable characters: among them Connor, the grouchy yet lovable outcast of the flock, crying for a mate but luckless in his pursuits, and "the lovers," Picasso and Sophie, inseparable until Sophie is forced into mourning when Picasso disappears. More than a mere birdwatcher, Bittner finds solace in his immersion with these strikingly beautiful creatures - but how will he cope when he's evicted from his sanctuary and forced to live away from the parrots?
