Barnacle Goose x White-fronted Goose
Barnacle Geese are common among feral geese flocks and hybrids involving
Barnacle Goose are frequently encountered.
White-fronted Goose is a much scarcer as a feral bird but some do occur, e.g. they were breeding at Cley (Norfolk, UK) for a number of years. A mixed pairing of Barnacle Goose x White-fronted Goose occurred at Raynham Lake (Norfolk, UK) a few years ago and were observed to be successful (per Andrew Bloomfield). A number of hybrid geese have been frequenting the area since then and at least two of these are presumed to be the offspring of this pairing.
