Comments: This is a common hybrid in North America, often referred to as “Brewer’s Duck”; eBird has numerous records in North America, but only eight for Nebraska. The range of variation in this hybrid is shown by Lehmhus in Bird Hybrids: Gadwall x Mallard). Leschack et al (2020) note that Gadwall hybridizes in the wild with Mallard, Northern Pintail, Northern Shoveler, and American Wigeon.
