Irruptions into the eastern U.S. are less common than in siskins and redpolls (about once every 10 years in some areas, Adkisson 1996) and involve far fewer individuals.   The list below includes all encounters of birds that moved over 100 km; it also includes all records of birds encountered a year or more after banding.
