Before 1995 nutcrackers were extremely rare in central and northern Norway. A great influx occured that autumn, and more than a thousand birds were recorded in the municipality of Trondheim alone. Apparently the species has settled in these areas as a breeding bird after this influx. The subspecies involved is the eastern macrorhynchos.
During autumn macrorhynchos prefer seeds of Pinus cembra (see lower picture), and collect these for food supply during winter. Note the broad white tailband, maybe the only field-feature distinguishing it from the caryocatactes subspecies (of course with some overlap).
Caryocatactes occur sparsely as a breeding bird in southeastern and southwestern parts of Norway. The pictures are from Gaulosen in Sør-Trøndelag county on the second of September 2002.
