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.
An intriguing report was of an apparent hybrid at Offutt Base Lake, Sarpy Co 30 Mar 2018; its identification was uncertain, but it was likely a mix of Ring-necked Duck and Lesser Scaup, or, based on its contrasting black and white appearance, Tufted Duck and Lesser Scaup, although the bird did have a pale area on its bill suggestive of Ring-necked Duck.
