Two Common Redpolls appeared at our feeder yesterday morning. Redpoll numbers fluctuate at about a two-year cycle. (It seems like it has been more than that since we have seen them here in numbers in central Minnesota.) Redpolls wander widely, A bird banded in Michigan was recovered in Siberia. One banded in Belgium was recovered two years later in China (All About Birds.) This source also cites a record of a seven-year, ten-month old Common Redpoll in Alaska.
