An examination of the banding files in the Biological Survey adds but little information to knowledge of the migrations of this bird. Although it has been banded in fair numbers (more than 1,700 previous to July 1, 1937) the farthest recovery record is only about 80 miles south of the point of banding. There are, however, several cases of return in subsequent seasons to the banding stations. _Casual records._--Records of this species outside its normal range are not numerous. A single specimen was taken in the Chiricahua Mountains, Ariz., in the spring of 1894; one was observed in Salt Lake City, Utah, in June 1874; and one was noted near Fortine, in northwestern Montana, on June 18, 1931. _Egg dates._--Alabama: 12 records, April 20 to July 15; 6 records, May 26 to June 17, indicating the height of the season.
