Status: Accidental in spring.
Documentation: An adult was found dead by NGPC staff at Harvard WPA, Clay Co 17 Mar 1997 (Brogie 1998).
Taxonomy: No subspecies are recognized. The genus Chen was recently lumped with genus Anser based on genetic studies (Chesser et al 2017).
Record: A dead adult picked up during a cholera outbreak at Harvard WPA 17 Mar 1997 (Brogie 1998) showed no signs of captivity and was determined to be a wild bird by the NOURC (Brogie 1998). William Lemburg, of Cairo, Nebraska, a long-time waterfowl collector, has kept this species in captivity, but has “never lost one” (William Lemburg, pers. comm.).
Comments: This species occurs with regularity as a vagrant on the Pacific Coast, the southernmost record in Orange Co, California. About half the records have been inland but not far from the coast, such as in the Lower Klamath Basin, but there are only two inland records, one in Nevada, 11 Dec 1960 (Mlodinow and O’Brien 1996) and one in Ada Co, Idaho 10 Nov 2000. Emperor Geese which are found inland tend to occur with Cackling or Greater White-fronted Geese (Mlodinow and O’Brien 1996).
