The southeastward migration through central Canada and the United States seems to be leisurely and quite prolonged, mainly in September and early October, but often continuing into November. In Massachusetts, there are numerous late fall records and some winter records. Horace W. Wright (1917) has published an extensive paper on this subject and has collected the following Massachusetts records: "Mr. Brewster's eleven records lie within the period of autumn from September 23 to November 28. There are three for September, namely, the 23rd and the 30th twice; none for October; and eight for November, namely, 7th, 9th, 10th, 17th, 20th-21st, 23rd-24th, 25th, and 28th. On two occasions two birds were present, November 9 and 28. My own records run later. The earliest is November 5, and the latest is January 23. They are November 5, 18, 20, 22, 28, 29, January 10, 19, 23." As Mr. Wright's records cover a period of 8 years ending with January 1916, they indicate that the orange-crowned warbler is not such a rare straggler in Massachusetts as is generally supposed, and may be looked for almost any year in late fall, or even winter. Mr. Forbush (1929) says of its occurrence there: This warbler may be found almost anywhere in New England during the fall migration wherever there are trees and shrubbery. In my experience the bird has been either in the trees or in the tops of rather tall shrubs and never very high, but like other members of the genus, though it nests on the ground it is said to spend considerable time in the upper parts of trees. It seems fond of the edges of woodlands near water, but it also frequents open woods, orchards, fruit gardens and shade trees, where amid the foliage it is very seldom noticed by the ordinary observer. When approached it divides its attention between the observer and its insect prey, which it hunts assiduously in the manner of others of the genus. This warbler may be seen rarely in small companies, but more often singly or in company with a small group of warblers of other species.
