Redhead
Aythya americana (Eyton, 1838)
AZ
1990
Family: Anseriformes > Anatidae
The Redhead is known to lay eggs in the nests of other birds, including at least 10 other duck species and even nests of the American Bittern and Northern (Hen) Harrier.
This duck breeds in the "Prairie Pothole" region of the western US and Canada, migrating to the southern US States in winter, so is only very rarely blown off-course sufficiently to reach our shores.
