We've had Wood Duck success (I think)! For the past several mornings, I've been seeing 5 Wood Ducks paddling around the pond - 2 pairs and one male. I'm pretty sure the missing female is actually in the nest box incubating her eggs. The incubation period for Wood Ducks is approximately 28 days, so by my estimation we should see little ducklings falling out of the box around April 26th.
