Aythya collaris x affinis
Status: Accidental in spring.
Record: The only record is of one photographed at Gavin’s Point Dam in Knox Co 1 Apr 2021 (Strand, eBird.org).
Comments: Ring-necked Duck hybridizes with several species of Aythya (Roy et al 2020). There are numerous records shown in eBird (eBird.org, accessed Jun 2021), but the Nebraska record is the first on the Great Plains north of Texas.
