Their father is still very vigilant. Today I saw him chase away another Australian Wood Duck which was just trying to feed beneath the bird feeders, and last week he was standing guard, wide awake, while the eight ducklings had a mid-day sleep in the shade of a tree. He stood with his back to the tree trunk, so nothing could sneak up on him from behind, standing bolt upright, constantly scanning the ground to make sure his charges were safe. It makes me wonder when he has time to sleep or eat.
The ducklings are still slightly smaller than an adult bird, and still have some of their juvenile feathers. See the captions beneath the photographs for more information.
