American Black Duck x Mallard Hybrid
Anas rubripes x Anas platyrhynchos

North 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.
