Redhead x Lesser Scaup (hybrid)

Aythya americana x AYTHYA affinis

Status: Accidental in spring.

Taxonomy: Redhead is known to have hybridized with each of the other four North American Aythya in the wild, Canvasback, Lesser Scaup, Greater Scaup, and Ring-necked Duck (Woodin and Michot 2020).

Record: A drake was photographed in the Gavin’s Point Dam area, Cedar Co 1 and Mar 2021 by Caleb Strand (eBird. org).

Comments: There are 20-25 instances of this hybrid combination scattered across North America, mostly in the Great Lakes area, although this Nebraska record and a few for eastern Colorado are the only ones for the Great Plains (eBird.org, accessed 17 Mar 2024). This is a relatively rare hybrid, not easy to identify; good details and excellent photographs of a Chicago area hybrid are at 25 Jan 2014 – Wolf Lake/Powers State Recreation Area, Chicago.
