Silo, right, with Scrappy, center, chinstrap penguins at the Central Park Zoo in New York on Friday. Silo and Roy, not shown, male chinstrap penguins, had found each other in the big city. They had remained faithful. They had even raised a child. But then, not too long ago, they lost their home. Silo's eye began to wander, and last spring he gave up his partner of six years and took up with a female from California named Scrappy. Of late, Roy has been seen alone, in a corner, staring at a wall. This tale of betrayal, sexual identity and penguin lust has reverberated around the world.Sep 25, 2005
