Sunrise 6:21 am: First duckling spotted

There it was, spotted just after the Dawn Joggers and Cassie - soon joined by Judy - climbed the steps onto Lake Lagunita's levee. One newly born duckling - only the tiniest speck in the photo just to the rear of its two parents - out for a morning swim. All agreed the it was odd to see just one duckling. Clearly not all eggs survive nor do all ducklings make it to adulthood. But neither the DJs nor Judy recall ever seeing just one duckling per pair before. Had the March rains washing away the other eggs in the nest?
