Ring-necked x Tufted Duck (hybrid)

[Ring-necked x Tufted Duck] (hybrid)

Aythya collaris x fuligula

Status: No accepted records.

Comments: A drake Aythya photographed in Cherry Co 10 Jul 2019 (Paul Timm, eBird.org) raised questions as to whether it was an unusual Ring-necked Duck or carried some Tufted Duck or other Aythya genes through backcrossing. Correspondence with hybrid waterfowl expert Jorn Lehmhus was inconclusive as to its identity, but Lehmhus suggested the possibility of an intergrade should not be dismissed. Unfortunately there was only one photograph taken.

Intriguingly, there is a record very close to Nebraska in Sedgwick Co, Colorado, also of a male (Mlodinow, Moore, eBird.org). The only other record in the central US, out of about 10 in all for North America, is for Minnesota 13 Dec 2018 (Svingen, eBird.org).
