High above the ground among the wetlands and marshes, a miracle is about to happen. In the hollow of a tree, a gray and brown female wood duck sits on her clutch of eggs. In just a few days, they will peck through the shells and hatch out as down-covered ducklings.
Right now, though, they are peeping inside their shells - and she is peeping right back. It is this preparatory communication that familiarizes the ducklings with their mother's voice. This is vital if they are to survive, because the female wood duck will soon shift from nest-sitter to survival-skills teacher and swim coach.
Within 24 hours of hatching, the ducklings must get to the water if they are to survive. The mother duck, sitting in the hole of the tree, scans the ground below. She knows mink and raccoons are often waiting in the woods. Other predators include snakes, hawks and owls. When satisfied the way is clear, she flies to the ground and begins calling her young.
