Alopochen aegyptiacus
Status: No accepted records.
Taxonomy: No subspecies are recognized (Gill et al 2022).
Comments: This species, actually a shelduck, has no history of vagrancy to the Western Hemisphere. It has been reported a few times in Nebraska with no discernible pattern of occurrence; all were presumably escaped or released birds. However we track these occurrences as indicators of incipient feral status.
The several Nebraska reports include 1 Jan 2006 with Canada Geese near Ponca SP, Dixon Co; 11 Mar 2006 Merrick Co, 29 Mar (year unknown) photographed at Elkhorn, Douglas Co; 27 Apr 2003 Dixon Co; 28 May 2016 Kirkpatrick Basin North WMA, York Co; 7 Jul 2023 Heartland of America Park, Douglas Co; 6 Aug 2016 photographed near Garrison, Butler Co; specimen, UNSM ZM16013, an immature male that hit a powerline Sep 1988 in Gage Co and had a clipped tail suggesting it was an escapee (Thomas Labedz, personal communication); 12 Sep 2021 (3) at Lakeland Estates, Washington Co; 6-11 Oct 2014 photographed at Branched Oak Lake, Lancaster Co (Michael Willison, personal communication); 11 Oct 1999 Calamus Reservoir, Garfield Co (Wayne Mollhoff, personal communication); and 13 Dec 2016 at Holmes Lake, Lincoln, Lancaster Co. Two apparently free-flying birds were with Canada Geese and Mallards at Henry Doorly Zoo, Douglas Co 28 Apr 2021 and three were there 28 Dec 2021.
Species maps in eBird (accessed Apr 2023) show established populations in northwestern Arkansas and large cities in Texas, Houston, San Antonio, Austin, and Dallas, as well as Dawson Co in northwestern Texas and Curry Co in eastern New Mexico. eBird reports in Oklahoma, Kansas, Missouri, South Dakota, and Iowa, as well as Nebraska, are not considered to represent established populations. As of Apr 2023, there are no eBird reports for Colorado. The closest established population to Nebraska is in northwestern Arkansas, where there has been an established and expanding population since the 1980s (Smith and James 2012). According to Chesbro (2015), “A final recommendation of this study proposes that northwestern Arkansas is a dispersal point for the Egyptian Goose for more suitable habitats in surrounding areas and should be eradicated from the area before the species follows other non-native species and becomes invasive.”
