This individual is much smaller than the feral Greylag Geese that it associates with. Its origin is unknown but in 2003 it was caught and ringed during a ringing programme targeting Greylag Geese at Lake Max-Eyth-See (Stuttgart-Hofen, Germany) and has been seen at several places in Stuttgart since.
Regarding its identity Joern refers to the mostly dark undertail-coverts which point to Emperor Goose as a likely parent. Despite the superficial resemblance to Hawaiian Goose the greyish chin patch approximates to Canada/Cackling Goose with the small size favouring Cackling.
