ラブラドル半島
This bird may have reached America either from Asia or from Europe (Greenland/Iceland). It is the extant parental species of one of the "Spinus"/"Carduelis" three evolutive North American radiations of "atriceps", "pinus" and "dominicensis" finches. It has been recorded both in the Aleutian Islands and the east: the Labrador Peninsula and St. Lawrence River mouth (Canada). This raises the possibility that this bird entered (or may still try to enter) America through Greenland/Iceland from Western Europe.
