First official record for Dakota County, per eBird and the MOU seasonal report database.
My observation notes from ebird list:
"GADW×MALL hybrid. Seen in direct comparison to Mallard and Gadwall. No curly retrices. Green crown, neck, and throat. Light brown auriculars with slight rusty color. Medium brown breast. Gray sides, white secondaries, gray-brown back all indicative of GADW. White underwings. Orangey bill with minimal black. See pics."
