Black bellied Whistling "Tree" Ducks or Dendrocygna autumnalis
Here's the duck hen on the afternoon of the 10th day of egg incubation.
She arrived at the box from her day off to replace the male duck at 8:37am.
The inside of the duck's beak or bill has lamellae that help sift food from silt.
Don't forget yawn after watching this video.
