Aythya americana x affinis
Status: Accidental in spring.
Record: One was at Gavin’s Point Dam in Cedar Co 21 Mar-1 Apr 2021 (Strand, eBird.org).
Comments: Redhead hybridizes with all four North American Aythya species in the wild (Woodin and Michot 2020). This is a relatively rare hybrid, not easy to identify; eBird (eBird.org) shows about 15 records across the US, the Nebraska record the only one on the Great Plains.
