Anser albifrons x Branta canadensis
Status: Accidental in winter
Taxonomy: Canada Goose and Greater White-fronted Goose have both hybridized with numerous species in genera Anser and Branta (Mowbray et al 2020).
Record: There is a single record, one photographed at Carter Lake, Douglas Co 12 Jan 2014 (Manning, eBird.org). The observer noted: “It was overall similar in appearance to a Greater White-fronted but the head had the faint pattern of a Canada Goose. The Graylag X Canada hybrid I have seen usually are much bulkier and the bill is the normal Graylag shaped bill.”
Comments: There are numerous records in eBird (accessed Feb 2021) across North America, suggesting this hybrid is more common than the single Nebraska record implies. Identification points include large size, orange legs and a diffuse whitish facial patch. Hybrids between Greater White-fronted Goose and the larger forms of Canada Goose can be very hard to separate from Greylag Goose x Canada Goose hybrids, according to information and photographs at Bird Hybrids: Greater White-fronted Goose x Canada Goose.
