Crested Duck
Anas platyrhynchos domesticus

Field Notes
Description:
The domestic Crested Duck is a selected duck breed descended from the Mallard. It has its appearance because it is heterozygous for a genetic mutation causing a deformity of the skull. In particular, this mutation causes the duck to be born with a gap in its skull, which is filled with a growth of fatty tissue. It is from this growth that the pouf of feathers sprouts.
I suspect the brown duck to be the proud father of the indian runner females' progenia shown in the previous spotting :-)
Habitat:
Pairi Daiza, Belgium.
