Today while looking through a large flock of 100 to 200 redpolls in Centre County PA, my eye was drawn to a redpoll that was larger and darker streaked than all the nearby redpolls. Dark redpolls from Iceland were almost indistinguishable from rostrata, but their average biometry was different from the pale birds breeding on the same island. Pale birds from Iceland are Species Detail - Greenland Redpoll (Carduelis flammea subsp. rostrata) - Species information displayed is based on the dataset "Birds of Ireland".

The pale phenotype from Iceland is the most distinct redpoll on that island, and might deserve a new name; the name islandica should be restricted to the dark, rostrata-like birds. The third type is the 'Greenland Redpoll' (C. rostrata), which is another winter visitor and is larger than the Common Redpoll and darker than the Lesser Redpoll. The final type is the Arctic Redpoll ( C. hornemanni ), which is a rare vagrant from Greenland and Lapland and is slightly larger than the 'Greenland Redpoll' and has a white rump and underparts.

All birds are large and dark with streaked rumps.
