Black Duck x Mallard Hybrid
Anas rubripes x Anas platyrhynchos
Pond in Chicago's Lincoln Park
Cook County, IL
13 January 2010
This apparent male, American
Black Duck x Mallard hybrid was with the large aggregation of waterfowl
wintering at Lincoln Park's North Pond. Note the wide green stripe
along the upper portion of the head. I was unable to get a peek at
the bird's speculum, so I don't know what it looks like.
Here the hybrid duck is
seen near a male Mallard.
Here the hybird is near
one of the three American Black Ducks that was on the pond that day.
