male bufflehead with half streaked hood


In the slough to the east of the Landfill Loop trail I saw a male bufflehead the back half of whose hood was white streaked just about vertically with gray. The demarcation was sharp and the two areas were about equal. I didn't get a good look at the other side of his head. I'd never seen this but perhaps it's more common than I am aware? It was certainly striking.
