Lee and Karen Rentz of Shelton, Washington have posted a series of youtube videos, captured from a camera inside their wood duck nest box.
This video shows the whole brood of what looks like 18 wood ducks and one hooded merganser scramble for the hole in the nest box. I feel for the last one.
Earlier videos show hatching, the mother incubating the eggs while getting visits from another wood duck. It also catches a hooded merganser laying an egg in the box.
Here's another video of another wood duck brood leaving the nest, but this one is taken from outside, showing the ducklings make the leap from the box to join their mother. Watch it with sound. The thumps are great.
