Anser fabalis middendorffii
Status: Rare casual winter visitor south and east.
Documentation: Photograph: 29 Dec -10 Jan 1984-85 DeSoto NWR, Washington Co (Rose 1985, Wright and Grenon 1985).
Taxonomy: The fabalis group of subspecies (fabalis, johanseni, and middendorffii), was formerly combined with the serrirostris group (serrirostris and rossicus) as Bean Goose (A. fabalis). The serrirostris group is known as Tundra Bean-Goose (A. serrirostris) and the fabalis group as Taiga Bean-Goose (A. fabalis) (Banks et al 2007) . More recent genetic information suggests the split may have been premature (Gill et al 2021).
Both Nebraska records are of A. f. middendorffii.
Winter: An individual was found by Alan Grenon and Rick Wright with Snow Geese at Desoto NWR, Washington Co 29 Dec-10 Jan 1984-85 (Wright and Grenon 1985). A photograph was published (cited above) and many observers saw the bird, for example Bill Huser, eBird Checklist – 5 Jan 1985 – DeSoto NWR (NE) – 1 species, which was assignable to the subspecies middendorffii.
Another observed by Stephen Dinsmore with Greater White-fronted Geese at Funk WPA, Phelps Co 4 Apr 1998 was also identified as middendorffii (Brogie 1999; eBird Checklist – 4 Apr 1998 – Funk WPA – 1 species).
Comments: The eastern Siberian subspecies middendorffii is rarely kept in captivity, which supports wild origin for a straggler to Nebraska (Bray et al 1986, Howell et al 2014).
