Spatula clypeata x Mareca strepera
Status: Rare casual spring migrant central
Records: There are three records:
20 Mar 2015 Harlan Co Reservoir, Harlan Co (Skaggs, eBird.org)
9 May 2020 York Co (Willison, eBird.org)
9 May 2020 York Co (Peterson, eBird.org). Likely same bird as preceding; eBird locations are about three mi apart.
Comments: Thought to hybridize with Mallard, Northern Pintail, Northern Shoveler, and American Wigeon in the wild (Leschack et al 2020). According to “Bird Hybrids”, this is a “highly distinctive hybrid”, and surprisingly exhibits a pale cheek, although the latter, as well as the bronze-colored cap, is shared by other Gadwall hybrids (Bird Hybrids: Gadwall x Northern Shoveler).
Although there are about 15 records of this hybrid on the Great Plains and 40+ for North America (eBird.org, accessed Feb 2017), there are only two records for Nebraska.
