In addition to the winter range above given, it also has been noted casually at this season in eastern Kansas and Nebraska, southeastern South Dakota (Yankton, January 2, 1929, and the winter of 1936-37); North Dakota (Grafton, specimen collected January 24, 1905); Minnesota (frequent in the southern part); Wisconsin (occasional north to Meriden and New London); southern Michigan (Grand Rapids, Lansing, and Detroit); southern Ontario (Coldstream, Toronto, and Kingston); southern Vermont (Bennington); and Massachusetts (Boston). _Migration._--The migrations of the red-headed woodpecker are imperfectly understood, and, as will be noted from the numerous casual winter records, individuals of this species sometimes winter north almost to the limits of the breeding range. This makes difficult the designation of early and late dates of migration. Nevertheless, the following dates may be considered representative of most seasons in that portion of the range where the species is normally migratory: _Spring migration._--Early dates of arrival are: New Jersey--Elizabeth, February 27; New Providence, March 13; Cape May, March 27.
