I was browsing through the fabulous pictures in the gallery when I happened upon Michael Hobbs' two photos of American Crows, pied. I have seen several of these around Ocean Shores the past two years and couldn't imagine what was with the crows with the white spots and stripes! Now I see I am not alone, or crazy. However I am uninformed about pied birds. Can someone explain what this is about? What causes it? How often it happens? Are their offspring pied? etc.
