Greenland White-fronted Geese Anser albifrons flavirostris have been recorded in Poland twice, during spring migration of 2012 and 2020 in the Biebrza Basin (NE Poland). During the first observation a single adult was recorded, while in 2020 two second-year individuals were found. These are the only records of this subspecies in Poland, which have been accepted by the Polish Avifaunistic Commission. The Greenland White-fronted Geese are rarely seen in Western and Northern Europe (except for their regular wintering range) and further east records are even scarcer. It is probable that individuals from the Greenland subspecies, which move beyond their regular range, rarely join flocks of the nominate form and migrate eastwards in spring, reaching Central and Eastern Europe. The field identification of the Greenland White-fronted Geese is summarized and discussed.
